									3. Survey

I. Overview
                The SURVEY program displays provide you with information to
                monitor survey data collection and to assure full coverage of the
                survey area. Customize the real-time displays and set the
                navigation parameters to suit your normal needs and preferences
                then use the easy keyboard commands to manually guide your
                data collection.
                SURVEY is run simultaneously with HYSWEEP® SURVEY or
                SIDE SCAN SURVEY to provide navigational data while
                HYSWEEP® SURVEY or SIDE SCAN SURVEY collects the
                multibeam and side scan data.

II. Survey Preparation
                The typical ―order of events‖ to get ready to survey is as follows:
                 Create a New Project. You can either create a new project
                   from ―scratch‖ by using the FILE-NEW command or copy
                   an existing project using the FILE-COPY menu command.
                   When you create a new project, your new project will
                   ―inherit‖ the last settings for geodesy and hardware. When
                   you copy a project, it copies everything from the previous
                   project, with the exception of the data files.
                 Check your Geodesy. If you have not previously specified
                   your geodesy, enter the GEODETIC PARAMETERS
                   program and configure your geodesy, as specified in Chapter
                   II under "Geodesy". If you have previously configured your
                   geodesy and it hasn‘t changed, proceed to the next step.
                 Check your Hardware. If you have not previously
                   specified your survey hardware, enter the HARDWARE
                   program and configure your survey equipment, as specified
                   in this manual under "Hardware". If you have previously
                   configured your hardware and it hasn‘t changed, you can
                   either skip the HARDWARE program, or go into it to test
                   your configuration.
                 Create your Planned Lines. If you are working on a new
                   project, you will probably want to create a Planned Lines
                   File (*.LNW). (See the section of this manual on "Planned
                   Survey Lines".) If you have copied a previous project, you
                   already have your planned lines and can go straight to

                The following tasks should be considered before you begin to
                collect data:
                 Configure the size, position and features of the display
                 Set the Navigation Parameters
                 Input the Project Information
                 Configure your Boat Features
                 Load and configure any Target Files (optional)
                 Load and configure any Matrix Files (optional)
                 Preset your Tide Corrections information (optional)
                 Automate your Draft/Squat (optional)
                The details on all of these features are described in the following

III. Starting the Survey Program
                Choose from 3 methods to open SURVEY:
                 Click the SURVEY icon (the whale).
                 If you are running only a Single Beam survey, select
                   SURVEY-SURVEY from the menu.
                 If you are running a Single Beam and a Multibeam survey,
                   select BOTH SURVEY AND HYSWEEP® SURVEY.
                The SURVEY program of HYPACK® loads the information
                from the current ―Project‖. It gets its geodetic information and
                hardware information by reading the initialization files from the
                project. It will load the most recently used Planned Survey Line
                file (*.LNW) from the current project as well as any Background
                Files and Matrix Files that are currently ―Enabled‖.
                To load additional files for display purposes only, you can do
                so through the CHARTS-LOAD option. Just select the file type
                you want then select the file. Once displayed, you can toggle
                them on and off through the Map Menu.

                Note that this option enables you to load several file types that
                        are not background charts but, like background charts,
                        they are for display purposes only.

       Survey Program

                           Survey functions can be executed through the menus in the shell
                           and in the individual windows, the (optional) toolbar, or through
                           keyboard shortcuts.
       Survey's Toolbar

                           The toolbar is a row of icons that duplicate the function of
                           several of the menu selections. To determine each icon's
                           function, hold the cursor over the icon and a tooltip will appear.

IV. Navigation Parameters
                           The Navigation Parameters window can be used to set several
                           SURVEY specifications. You can access this window by
                           selecting OPTIONS-NAVIGATION PARAMETERS.
       Parameters Dialog

                           The Start Line Gate can be used to automatically go ―On Line‖
                           when the distance from the tracking point to the start line point is

2/08                                                                                   Survey • 3-3
               less than the absolute value of the entered distance. (See the
               section on Logging Data in Survey.)
               The XTE (Cross Track Error) Alarm Limit can be set to
               activate the alarm feature of the Left-Right Indicator if the
               tracking point is off-line farther than the entered distance. The
               XTE Alarm Limit can also be changed by clicking and dragging
               the tabs in the Left-Right Indicator.
               The Next Event item sets the number of the next event mark.
               The SURVEY program ―remembers‖ the last event number
               when it is shut down and, when restarted, will begin numbering
               event marks at the last number.
               The Event Interval represents either the Time (secs.) or
               Distance (survey units) between event marks, depending on
               which method you have selected under the Event Basis frame.
               The Event Increment is the amount the event number changes
               when a new event is generated. If you want your events to go 1,
               6, 11, 16, etc., set the Event Increment to ―5‖.
               The Next Line shows the number (name) of the next survey line.
               The Line Increment shows how many lines the SURVEY
               program will increment through the line queue when it finishes
               with the current line. For example, if you are currently
               surveying line #25 and the Line Increment is ―3‖, the next line
               will be Line #28. You may have negative Line Increments,
               which allows you to step ―backwards‖ through the line queue.
               The Log Backup Time is explained in the section on ―Logging
               Data-Closing Data Files based on Time‖ and the Matrix
               Backup Time is explained in the section of this chapter on
               Matrix Files.
               Seabed Sound Velocity will record the Sound Velocity
               corrections to the Raw datafiles. This is needed at this time for
               the benefit of the SeabedID driver. If you are using the seabed
               identification programs, select this option. If you are not using
               the seabed identification programs, you can use this to eliminate
               the need to apply the Sound Velocity Corrections later.
               Checking this option and later running the SOUND VELOCITY
               program will not double the corrections, it just overwrites them
               with the same values.
               Minimum Depth sounds an alarm when the depth reading is less
               than or equal to a user-defined level.
               Reset Events at Startup begins counting events at 1 each time
               you launch the SURVEY program.
               Time Events on Even Intervals is used with the option to set
               event marks based on time. If you prefer your event times to be
               nice even numbers, checking this option will cause SURVEY to
               mark the first event after the start line event on an even minute

3-4 • Survey                                                                       2/08
                (no seconds), then according to the time interval set in the Event
                Increment field after that.
                Connect Events with Segments does just that, it draws straight
                lines between event marks as they are created.
                Event Basis determines when events will be created. You can
                create them manually (Ctrl+N) or automatically based on time
                (secs.) or distance (survey units).
                The Automatic Leg Switching is used by SURVEY to
                determine how to step through multiple segment planned lines.
                The available choices are:
                 While Logging: Using this method, the current segment is
                    fixed until the program goes ―On Line‖. It then
                    automatically switches to the closest segment, based on the
                    off-line distance of each segment.
                 Always: This method constantly updates to the most
                    appropriate segment, whether the program is ―On Line‖ or
                    ―Off Line‖.
                 Never: This will not change the current segment. You may
                    manually change segments using the Ctrl-F (Forward
                    Segment) or Ctrl-B (Backward Segment) key commands.
                Line Direction Mode tells SURVEY the pattern the survey
                vessel will normally follow when a new planned line is selected.
                 Closest looks for the end of the line closest to the vessel and
                    assumes you want to run the line starting from that end.
                 Line Origin starts the line at the first set of coordinates for
                    the line in the Planned Line File. This is useful for surveyors
                    who want to run all of their lines in the same direction.
                 Line Terminus starts the line at the last set of coordinates
                    for the line in the Planned Line File. This is useful for
                    surveyors who want to run all of their lines in the same
                 Alternate Direction starts the next line in the opposite
                    direction from the direction of current one based on the
                    coordinates entered in the Planned Line File. (Alternates
                    Origin-to-Terminus, then Terminus to Origin.)

V. Project Information
                Select OPTIONS–PROJECT INFORMATION and the
                following dialog appears.
                The Project Header data which is written to the header of the
                data files is defined in the Project Information dialog. The
                header data is optional, (for display purposes only) but a year
                from now you may be thankful that somebody took the time to
                fill out the available fields.

 VI. Raw Survey Files
         A. Survey File Naming Convention
                              Every time the SURVEY status switches to ―ON-LINE‖, a new
                              data file is created with a unique name.
                              You can choose your file naming format from the following
                              choices by selecting OPTION-PROJECT INFORMATION.
Naming Format             Description                             Example
Standard HYPACK®          (See details below.)
  Named Lines             LineName.RAW                            34P00.RAW

                          + time(HHMM)
Julian Day as Extension   HYPACK® name with Day Number            014A1325.091
                          as the extension
Other Extension           You define the extension in the         014A1325.NEW
                          adjoining box.
                              Standard HYPACK® Details:
                               If your lines have names, your data file will be the name of
                                 the planned line, plus the extension. For example, if you are
                                 surveying a line named ―34+00‖, the resulting data file will
                                 be named ―34P00.RAW‖. If you survey the same line again,
                                 it creates a data file named ―34P00A.RAW‖. If you survey
                                 the same line once again, it creates a data file named
                                 ―34P00B.RAW‖, etc.

3-6 • Survey                                                                                     2/08
                          Line names of three or less numeric characters are an
                          exception; they will be named as if the lines do not have
                         If your lines do not have names, your data file will be
                          named using a combination of the start line time from the
                          computer clock and the number associated with the line. For
                          example, if you begin line #14 at 13:25, the survey
                          information will be stored in a data file named
                          ―014_1325.RAW‖. If you start the same line again during
                          the same minute, a data file named ―014A1325.RAW‖ will
                          be created.
                      It is impossible to duplicate or overwrite existing files in the
                      SURVEY program.

       B.Data Directories for Raw Survey Files
                      When you create a new Project, HYPACK® creates a sub-
                      directory under the \HYPACK\Project directory with the name
                      of your project. It then creates a directory named ―Raw‖ under
                      the directory. For example, if your new Project was named
                      ―Richmond 1998‖, your raw data files from the SURVEY
                      program would be stored in the ―\HYPACK\Projects\Richmond
                      1998\Raw‖ directory.
                      The SURVEY program stores your survey data, by default, in
                      HYPACK®‘s ―Raw‖ format in the \RAW directory under the
                      current project.
                      To specify another directory path, select FILE-PROJECT
                      DIRECTORIES from the HYPACK® menu and set a path for
                      each file type in the Project Directories dialog.

       C.Catalog Files for Raw Survey Files
                      The SURVEY program also saves a list of the data file names in
                      a ―Catalog‖ file (*.LOG). The Catalog file is handy when
                      processing or performing batch operations on the raw data files.
                      Instead of having to enter the name of 50 different data files, you
                      only need to enter the name of the Catalog (*.LOG) file.
                      Catalog files are named using the extension ―.LOG‖ and the date
                      of survey. They are written to the same directory where your
                      Raw data files are stored.
                      For example, if you are surveying on December 27th, a Catalog
                      file named ―RAW_1227.LOG‖ will be created. If you shut
                      down the SURVEY program and re-start it during the same day,
                      it will re-open any existing Catalog file and append the names of
                      new Raw data files to it.

VII. Windows in Survey
                          The following display windows are available in the SURVEY
        Area Map:         This is a plan view of your survey area. It displays any planned lines
                          background files, matrix files along with the position of the survey
                          vessel and its track line.
        Left-Right        Shows the position of the boat relative to the current planned line
        Indicator:        segment.
        Data Display:     Shows textual information regarding the survey.
        Profile           Displays the cross section profile and off-line information for the
                          entire planned line.
        Device Windows:   Each device (GPS, Echosounder, etc.) has an independent window
                          that displays information relative to that device.
        Alarms:           Alarms are displayed along the bottom of the SURVEY screen.
                          These are used to denote error conditions to the operator.
        Helm Area Map:    A second area map intended for use on helmsman monitors.
        Helm Left-Right   A second left-right indicator intended for use on the helmsman
        Indicator:        monitor.
                          These windows will initially appear in a cascade. You may
                          reposition and size them by selecting WINDOW-TILE or
                          clicking and dragging the title bar and window edges. Once you
                          have sized and placed the windows on the screen, the SURVEY
                          program will remember and restore them to the same status and
                          location each time you start the SURVEY program.

         A. Area Map in Survey
                          The Area Map window contains a plan view of your survey area
                          that includes all files active in HYPACK® when you start
                          SURVEY, and any additional files loaded through SURVEY's
                           Background Files that have been entered into the Project in
                               the HYPACK® main program will be loaded. They will be
                               displayed with the ―Chart–― prefix.
                           Planned Lines
                           Target Files
                           Projection Grid and Lat-Long Grid: These items ―Auto-
                               Scale‖, based on the scale of the Area Map.
                           Active Matrix files
                           Corrected or Raw Soundings and/or Events at each event

3-8 • Survey                                                                                2/08
                             directory. Each day, separate Sounding and Event files are
                             created. The SURVEY program automatically re-loads each
                             file to provide you with a history of the day‘s survey.
                         Sounding colors are determined by the project‘s color settings.
                         The position of the survey boat is updated on the Area Map at an
                         interval defined by the Update Frequency in the HARDWARE
A sample Area Map

                         Most project file types can also be loaded to your display
                         through the Chart Menu as background files only. Once
                         displayed, you can toggle them on and off through the Map
                         When you exit the SURVEY program, it records the status of the
                         items in the Area Map and restores the same configuration when
                         you re-start the program.

              1) Area Map Tracking and Orientation Options
                          Tracking and Orientation options can be used to
                          automatically re-adjust the screen when the boat leaves the
                          display area and to rotate your map to your preferred
                          orientation. These options are set independently for the Map
                          and Helm Map displays. A handy feature for the helmsman
                          who may want a closer view and different orientation than
                          anyone else on the vessel.
                          Select MAP-TRACKING/ORIENTATION from the menu and
                          the Orientation and Tracking dialog will appear.

                         Vessel Tracking:
                          In Center returns the boat to the center of the screen as it
                            nears the edge.
                          Look Ahead moves the boat further back from the center to
                            maximize the amount of space displayed ahead of the vessel.

2/08                                                                              Survey • 3-9
                                 Vessel and Target keeps the boat and the current active
                                  target in view. The map automatically zooms to fit as you
                                 No Tracking allows you to move the screen anywhere you
                                  want without having it zoom back to keep the boat in view.
                                  (Strike the Home key to center the vessel on your screen.)
                              If you set your preferred method of tracking, you can quickly
                              toggle between this setting and ―No Tracking‖ by selecting
                              MAP-TOGGLE TRACKING or by a simple click of the ‗T‘ key.
                              Map Orientation:
                               Vessel Up aligns the Area Map with the current vessel
                                heading. Define a threshold (in degrees) to determine how
                                much the vessel heading must change to cause the map
                                orientation to adjust. This prevents constant (annoying)
                                updates of the map orientation with only small changes in
                                vessel heading.
                               Line Up draws the screen so the current line segment is
                                directly ―up‖ the screen. If you are in the ―Line Up‖
                                orientation, the boat should be progressing up the screen. If
                                your boat is going ―down‖ the screen, you need to ―whip‖
                                the line ends (change the start-line and end-line points) by
                                using the Ctrl-W key command or the LINE–SWAP menu
                               User-Defined Rotation draws the Area Map according to
                                the specified degrees. Zero degrees will orient the map with
                                North up.

                2) Area Map Display Controls
                              The Area Map automatically loads and displays all Background
                              Files, along with the current Planned Line File and any
                              ―enabled‖ Matrix File in the project.
  Print Menu            Print-Save Bitmap saves a bitmap record of the current Area Map
                        window to the project directory.
                        Print-Print Map sends a copy of the Area Map to the default
                        Windows® printer.
  Zoom Menu             Zoom -Zoom Window enables you to click and drag a window inside
                        the Area Map. The SURVEY program will adjust the size of your
                        window to keep the scale as orthometric as possible.
                        Zoom In and Zoom Out can also be accessed by placing the focus on
                        the Area Map (click on it) and then hitting the ―+‖ or ―-― keys
                        Zoom Contents will zoom the screen to include all of the items that
                        are currently enabled in the SURVEY program. These items are
                        displayed in the bottom portion of the Map menu (shown above).
                        Items that are ―Enabled‖ are displayed with a leading check mark.

                 Note: The Zoom functions are more easily available using the icons on the

                         Range options allow you to quickly scale the map display. Just
                         select a range in SURVEY‘s toolbar, SURVEY will
                         automatically scale the selected Map window so the length of
                         shortest side displays the selected real-world distance. Each
                         subsequent window resize will adjust the scale accordingly, but
                         any zoom action will cause the range to revert back to "none".
                         The default range values are 500, 1000, 2000, 3000, 4000,
                         however, you can modify them by entering a new list in the
                         System tab in HYPACK® HARDWARE.
                         Move options (or the arrow keys) can be used to pan the screen.
                         Rotate options turn the area map display.
                         Grid Properties set how the projection and lat/long grids are
                         presented on the screen. You can choose automatic or fixed
                         spacing and the style of the labels. Labeling is available on all
                         four sides of the map.

       B.Left-Right Indicator in Survey
                         The Left-Right Indicator window only appears when you have
                         planned lines loaded into the SURVEY program. It shows the
                         position of the survey boat relative to the planned survey line.

                 2) Font of the Left-Right Indicator
                             The Font displayed in the moving bar can be changed to meet the
                             needs of different operators. These settings override the current
                             scheme until you exit SURVEY.
                             1. Place the focus on the left-right indicator by clicking on it
                                 to display the ―Left/Right Indicator‖ in the menu bar.
                             2. Select LEFT/RIGHT INDICATOR-FONT. The

                                The tab indexes are shown in the figure above, located between
                                the 20 and 200 offset. When the boat travels outside this range,
                                the graphical indicator will turn either red (planned line is to
                                starboard) or green (planned line is to port). This has no effect
                                on the data logging and is only a visual alarm to the helm to steer
                                toward the survey line. When this setting is changed, all other
                                displays of Cross Track Error update accordingly.

         C.Data Display Window in Survey
                                The Data Display window is used to display textual information
                                about the survey. These settings override the current scheme
                                until you exit SURVEY.

                                When you first start the SURVEY program, the display will not
                                contain any items. You choose the data to be displayed, and the
                                order and the font used to display each item.
                                Once the Data Display has been configured, the SURVEY
                                program will restore the items and font in the same way, when
                                the program is re-started.
                                You can access the Data Display menu by placing the focus on

                                is a tree view list of ―Available‖ items. On the right is a list
                                of the current ―Displayed‖ items. You can move an item
                                from one list to another either by double clicking on the item
                                or by clicking on it then clicking [Add=>] or [<=Remove].
                             Items will appear in the Data Display in the order they have been
                             added to the Display list. To re-configure the entire order, just
                             click and drag the items up or down the Display list.
                             Each vessel (SURVEY supports multiple vessels) will have a list
                             of items, which will be preceded by the vessel name in your Data
                             Display window. For example, if you have a main ship and a
                             towfish named ―ROV‖, you will find items named ―ROV–East‖,
                             ―ROV–North‖, etc.

                             Note: If you are surveying with only a multibeam system, the

Selecting the font for the
Data Display

                             Items in the Data Display can be enhanced (written in a bolder
                             font) to make them stand out among the other items. In the Data
                             Display Window figure above, the Depth has been enhanced.
                             To “Enhance” an item:
                             1. Select DISPLAY–CONFIGURATION.
                             2. Click on the item in the ―Display‖ list you want to enhance
                                and then click the ―Enhanced‖ box.

                             Note: The ―Enhance‖ feature will work best, if you are using a
                                    standard font. If you have selected a ―Bold‖ type font, it
                                    will be less effective.

                 3) Colors in the Data Display Window
                             Items that are generic to the entire survey (e.g. Time, Tide,
                             Line Number, File Name and Status) default to Black. You can
                             change the color through the Font dialog.
                             Items that are specific to one vessel will be drawn in the color
                             corresponding to the vessel's Symbol Color. Access the Symbol
                             Color of a vessel, right-click on the vessel in the Area Map.

         D.Profile Window in Survey
                             The Profile window only appears if you have planned survey
                             lines loaded in the SURVEY program.
                             The upper portion of the Profile Window shows a cross
                             section view of the entire planned survey line. This will
                             automatically display if the planned line file contains channel
                             template information. Otherwise, you will need to load that
                             information separately as described in the following section.
                             The bottom portion of the Profile Window shows the track
                             line of the vessel super-imposed against the planned line. This
                             enables you to determine whether the vessel stayed within a
                             user-specified off-line distance.

                           The Profile Window remains on the screen until the next survey
                           line is begun (status changes to on-line). Then, the Profile

                            An Advanced Channel file (*.CHN) from ADVANCED
                               CHANNEL DESIGN.
                            A combination of a 2-dimensional center line created in
                               the LINE EDITOR and a template (*.TPL) created in

                               line representing the center line of the channel. It can be a
                               multi-segmented line. Create the Template file referencing
                               the distances to the center line; negative values are left of the
                               center line and positive values are right. Negative depths
                               will be recognized as points above chart datum. The
                               program will automatically enter the correct depths and
                               widths according to the template information. The resulting
                               channel will also be displayed in the Map Window.
                           To load these features:
                           1. Select CHART-CHANNEL and the Channel/Center Line

                2) Channel Profile Settings in Survey
                            To configure the Profile Window, select VesselName
                            PROFILE–SETUP. The Profile Setup Window will appear.
                            The Depth options and Parallel Profile options affect the depth
                            portion of the window, while the Cross Track portion affects the
                            track line portion of the window. The Perpendicular Profile and
                            Dredge Setting options will be disabled as they are only
                            available in DREDGEPACK®.
The Profile Setup

                            The Minimum Depth and Maximum Depth are used to set the
                            depth values at the top and bottom of the depth portion of the
                            Profile Window.
                            The Mark1 and Mark2 Depths can be used to place two
                            reference depths on the Profile Window depth display. If these
                            values are ―0.0‖, no line will be drawn.
                            The Left/Right Limit is used to specify the range in the track
                            line portion of the Profile Window.
                            The Number of Channels in One Trace is used to combine
                            traces from multiple transducer systems. For example, if you
                            had a 32-transducer system and enter ―4‖ for this item, it would
                            average every four sets of transducers to a single trace and draw
                            eight traces (32/4) to the display.

2/08                                                                                 Survey • 3-17
                         The Trace Offset is used to separate the cross section profiles
                         for multiple transducer systems. For example, if you specify
                         ―5‖, it will offset each trace by 5‘ or 5m on the graph. This does
                         not influence recorded values. It is only for display purposes.
                         Parallel to Line is the only view available in SURVEY.
                         The Cross Track options display the track line portion of the
                         profile window and specify the range left and right of the survey
                         line that it shows.
                         Click [Colors] to set colors for each trace, the channel and the
                         Mark1 and Mark2 lines. Just select a trace then slide the color
                         slide to create the color that you want. Do this for each item
                         then click [OK].
Setting Profile Colors

                         You can adjust the horizontal and vertical scales of the graph
                         through the following keyboard shortcuts:
                          Contract horizontal scale:         Ctrl+C
                          Expand horizontal scale:           Ctrl+V
                          Decrease Vertical scale:           Alt+C
                          Increase vertical scale:           Alt+V

         E. Device Windows in Survey
                         Each device you have selected in the HARDWARE program
                         will generate it‘s own window. The device driver, not the
                         SURVEY program, controls the content of each window. This
                         means that the information for different devices will vary.
                         For example, some GPS systems will have only the Latitude and
                         Longitude displayed, while other GPS devices will have number
                         of satellites, HDOP graphs, error ellipses and other information.

         F. Alarms in Survey
                         Alarm windows are located along the bottom of the SURVEY
                         screen. When the criteria are met, the alarm window turns red
                         and the Windows Exclamation alarm sounds. You can turn off
                         the audio alarm by pressing the Escape key. This will also

                                     change the alarm boxes to yellow until the reason for the alarm
                                     has been corrected.

              G.     Helmsman Display in Survey
                                     HYPACK® has secondary Area Map, Data Display and Left-
                                     Right Indicator windows. These windows are intended to be
                                     used as a helmsman display in systems where a ―Virtual‖ screen
                                     that spans two or more monitors is in use.
                                     The Helmsman Windows are preceded with the ―Helm‖
                                     identifier. You can independently set the features for each
                                     window. For example, the items and fonts in the ―Helm Data
                                     Display‖ can differ from the items in the ―Data Display‖. The
                                     scale of the ―Helm LR Ind‖ can differ from the scale of the ―LR
                                     Ind‖. If you are not using these windows, they can be
                                     ―Minimized‖ by clicking on the minus box located in the upper
                                     right-hand corner of the window.

                                     Note: To use the dual monitor mode, you need special video
                                            cards that are supported by your operating system.
                                            HYPACK® does not create the Virtual monitor. It only
                                            allows you to drag windows to a separate, active virtual

     The Trace file is named RAW date.txt (for example RAW0927.txt) and saved in your project directory. It
   contains basic information about which files you are using as you survey, as well as data about events,
   targets, logging, etc. You can read it with any text editor.

         H.Broadcasting Survey Windows over the Network to the
              Survey Viewer
                       The SURVEY program broadcasts its windows over the local
                       network to be received by any computer using the SURVEY
                       VIEWER program. You can send and receive broadcasts on the
                       same computer in order to create a helmsman display on one
                       monitor and the survey window on another, or monitor a survey
                       or dredge offsite via a wireless network.

                       Note: SURVEY windows can only be configured through
                              SURVEY. SURVEY VIEWER only views the windows
                              as they appear in SURVEY.

                       SURVEY VIEWER is the program that will receive the
                       window broadcast over a network and must reside on the
                       receiving computer. It is a free-standing executable that requires
                       no license or hardlock. The SURVEY VIEWER program and its
                       supporting files are found in the \hypack\survey viewer folder.
                       Copy these files to a single file, in any location, on the receiving
                       1. Launch the SURVEY VIEWER by selecting

VIII.Boat Features in Survey
                        You can configure the display options and draft correction for
                        each vessel through a Vessel Setup dialog. In addition, the Map
                        and Helm Map windows can display the same vessels identically
                        or differently, each according to its own vessel setup.

Vessel Setup Dialog

                        The Vessels menu lists each vessel included in your hardware
                        1. Select the vessel whose features you want to modify from
                            the Vessels menu and the Vessel Setup dialog for that vessel
                            will appear for you to customize your vessel display. (The
                            options are described in the following sections.)
                        2. Set whether your settings should affect the Map or Helm
                            Map display by checking the corresponding checkbox.
                        3. Choose your vessel settings and click [Apply]. The Apply
                            button is useful for a couple of reasons. It allows you to:
                                 Preview your display before exiting the dialog. If
                                    it doesn't suit you, make some adjustments and
                                    check again before exiting the dialog.
                                 Define settings for multiple windows. Just apply
                                    your settings for one window, then change your map
                                    designation and repeat the process for the other map
                        4. When you are satisfied, click [OK].
                        The configuration for each vessel is saved when you exit the
                        SURVEY program and are restored when you re-start the

         A. Boat Track Parameters
                        The track parameters enable you to control the track line display.
                        Show the track line by checking Visible Track.
                        Track Length defines the number of updates included in the
                        display. (More updates results in a longer displayed track line.)

3-22 • Survey                                                                                2/08
                        Damping is the number of previous position updates used to
                        calculate the ship speed and course made good. The Speed and
                        Course Made Good (CMG) are normally taken from external
                        devices (e.g. your GPS). If there is no external Speed of CMG
                        device, the SURVEY program will calculate these.
                        Click [Color] to select the color of the track line from a color
                        Vector draws a line that projects the future path of the vessel
                        from the tracking point using the current heading and speed.
                        The length of the vector line is determined by the number of
                        seconds entered in this field. For example, an entry of zero
                        draws no vector. An entry of 20 will draw a vector from the
                        tracking point to the position at which the tracking point will be
                        in 20 seconds if the vessel continues at the same heading and
                        Range Radius displays a circle around the vessel, centered on
                        the tracking point at a user-defined distance measured in survey

       B.Boat Shapes and Symbols
                        You can assign a custom Boat Shape, created in the BOAT
                        SHAPE EDITOR (*.SHP), or a top-view drawing in DXF format
                        to a vessel by clicking [Select Shape]. It will bring up a listing
                        of the available shapes, defaulting to the \HYPACK directory.
                        (See the Boat Shape Editor for details on creating a boat shape.)
                        The DXF must meet the following structure requirements:
                         DXF Version 12
                         HYPACK® boat origin should be at (0,0) point.
                         All drawing objects must be polylines.
       DXF Boat Shape

2/08                                                                               Survey • 3-23
                        Once a shape has been assigned to a vessel, you can toggle
                        between the shape and symbol using the Display Shape option.
                        If a boat does not have a shape associated with it, it will be
                        drawn with either a circle, box or fish symbol. You can select
                        the one you want from the Symbol area of the Vessel Setup
                        The symbol color is displayed below the symbol selections.
                        You can change this by clicking in the color square and selecting
                        a new one from the selection dialog that appears. This also
                        determines the outline color of any boat shape that may be
                        assigned to this vessel, as well as the color used to display text
                        information about the boat in the Data Display.

                        Note: If you have multiple vessels, you can keep track of
                               different ones by assigning different symbol colors for
                               each vessel.

                        The Fill Color is the color used to fill a boat shape. You can
                        assign the fill color by clicking in the color square and selecting
                        a new color from the color selection dialog that appears. Note
                        the fill color is independent of the symbol color. A white fill
                        results in a transparent shape allowing you to view items (such
                        as chart information, soundings, planned lines, etc.) that may
                        otherwise be obscured from view.

         C.Labeling your Vessels in Survey
                        The Label Vessel option is used to place a short label on the
                        vessel. This feature is useful when tracking multiple vessels.
Labeling the boat

                        Note: Vessel names (determined in the hardware setup) should
                               be kept short, as the SURVEY program needs to capture
                               the entire area surrounding the boat and label. If boats
                               and labels overlap, the display can get confused as it
                               captures pieces of other labels. This can be re-set by
                               zooming the screen in/out one time.

         D.Specifying the Main Vessel in Survey
                        For applications with multiple vessels or a vessel and tow-fish,
                        one vessel should be set as the ―Main Vessel‖. The main vessel

3-24 • Survey                                                                                 2/08
                       is used for displaying Cross Track Error and Distance To Go
                       information. It is also used for the automatic Start Line and End
                       Line decisions.
                       To set your selected vessel as the Main Vessel, check that box in
                       the Vessel Setup dialog. Checking this box will automatically
                       clear this option for any other vessel.
                       If you are tracking an ROV or using a towfish, it is desirable to
                       make the ROV or towfish the main vessel.

       E. Position Filters in Survey
                       GPS devices can occasionally generate an inaccurate reading.
                       Position spikes such as this may cause a problem for users who
                       are using automated features such as switching planned line
                       segments, cross-track error, and Start and End Line Gates to
                       control data logging in Survey.. The position filters provide
                       criteria for SURVEY to recognize a bad position and ignore it
                       for these purposes.
                       The Dead Reckoning option tells SURVEY to calculate a
                       position based on current heading, speed and elapsed time since
                       the last position, and use it in place of a rejected position.
                       Gate Distance is the maximum distance allowed between two
                       consecutive positions when the vessel is stationary. Each time
                       SURVEY receives a position, it calculates the distance it should
                       be from the last recorded position based on the vessel speed and
                       elapsed time since the last position. It compares that calculated
                       distance against the actual distance. If the actual distance
                       exceeds the calculated distance by more than the gate distance,
                       SURVEY records the position to the data file, but ignores it for
                       the purpose of SURVEY‘s automated features.
                         Use a value slightly larger than your expected GPS error.

                       Maximum Consecutive Positions Rejected limits the number
                       of points that can be rejected without accepting one. If
                       SURVEY has rejected this number of consecutive position
                       readings, it will accept the next position regardless of where it is.
                         Calculate the number of positions you would normally log over
                         the distance where you lose signal and use a value slightly

       F. Displaying Boat Profile Windows
                       You can toggle the Profile Window display for a particular
                       vessel with the Display Profile option. It is useful to disable the
                       display if the vessel does not have any depth sensor.

2/08                                                                               Survey • 3-25
         G.     Anchors in Survey
                                Up to nine anchors can be attached to your boat shape using the
                                Boat Shape Editor routine. The ―Boat Points‖ are entered by
                                typing the X-Y distances (in the same units as your survey
                                projection) from the boat origin to various points along the
                                perimeter of the vessel.
                                In the lower left area of the Boat Shape Editor, you can attach
                                anchors to the shape. These anchors will be referred to as
                                ―Anchor 1, Anchor 2, …., etc.‖ in the order they have been

                1) Dropping an Anchor in Survey
                                Once you have loaded your boat shape file with anchors
                                attached, you can drop anchors at any time.
                                This can be done through:
                                 The Keyboard Shortcut: Focus on the Map window, hold
                                   Alt and a number key that corresponds to the anchor number.
                                   (For example Alt+1 drops Anchor 1.) You can raise the
                                   anchors in the same manner.
                                 The Vessel Setup Dialog.
                                   a. Open the Vessel Setup Dialog by selecting VESSELS
                                       and the vessel name. The setup dialog for vessels
                                       configured with anchors includes a set of anchor

                                    b. Select the anchor number you want to drop then
                                        click [Drop]. The anchor will be dropped at the current
                                        anchor position and displayed on the screen.
                                   Check Drop at Target to drop the anchor at a selected target
                                    location rather than at the current anchor location.

                2) Raising an Anchor in Survey
                                You can raise an anchor through:
                                 The Keyboard Shortcut: Focus on the Map window, and
                                   press Alt + number key that corresponds to the anchor
                                   number. (Ex. To raise anchor #3, use Alt+3.)
                                 The Vessel Setup Dialog.
                                   a. Open the Vessel Setup Dialog by selecting VESSELS
                                       and the vessel name.

                                    b. Select the anchor number you want to raise then
                                       click [Raise]. The anchor will be dropped and displayed
                                       on the screen.

                3) Displaying the Distance to an Anchor in Survey
                                You may display the horizontal distance from an anchor to its
                                attachment point on the vessel by right clicking on an anchor. In
                                the popup display, "L=" will display the horizontal distance in
                                the current survey projection units. Right click on the L=
                                equation to label the anchor with a distance label that is updated
                                in real time.

IX. Chart (Background) Files
                                The SURVEY program automatically loads any background file
                                which is active in the HYPACK® main program. Supported
                                chart types are included in the Introduction chapter under
                                ―HYPACK® Project Files‖.

                       1. Select CHART–LOAD. A file selection window will
                       2. Select the desired file type and the name of the data file
                          you wish to add to the SURVEY Area Map.
                       Chart Geodesy:
                       For Chart data to be correctly drawn, the geodetic parameters of
                       HYPACK® must match the geodetic parameters of the
                       background file (BSB, DIG, DGN, DGW, DXF, TIF, ARCS).
                       For data stored in WGS-84 (C-Map, S57, VPF, ARCS), the
                       SURVEY program will transform the data files to the local
                       datum, using the datum transformation parameters in the
                       GEODETIC PARAMETERS program before converting them to
                       your projection. This allows you to use these file formats on any
                       Draw Order:
                       Charts inside the SURVEY program will draw in the order they
                       have been loaded. If you have a Chart which has a solid
                       background (e.g. BSB, S57, TIF, VPF), these will obliterate
                       other types of background charts.
                       It is sometimes necessary to draw DGN or DXF files on top of
                       BSB, S57, TIF or VPF files. The SURVEY program can
                       perform this task. The secret is to specify the files in the correct
                       order. Specify the ―solid‖ background files first and then the
                       DXF and DGN files.

                       Note: Vector Product Format charts may also be loaded from
                              SURVEY through the Chart menu. The process is the
                              same as loading them to HYPACK®.

                              [Remove]. The screen will now redraw without the file you
                              have ―unloaded".

X. Targets in Survey
                           A Target represents a location and a name. In HYPACK®,
                           targets can be used to mark navigation aids (buoys, beacons,
                           etc.), or locations where you take water quality or bottom
                           samples, or the ―Waters Edge‖ location when surveying on
                           When you mark a target, the SURVEY program will draw it to
                           the area map and store it to the Target file enabled in the project.
                           If no Target file is enabled, SURVEY automatically creates a
                           Target File named with the format mmddyyyy.TGT (where
                           ―mm‖ is the month, ―dd‖ is the day and "yyyy" is the year) and
                           stores it in the current Project directory. For example, if a Target
                           is marked on October 25th, 2000, it is stored to a target file
                           named 10252000.TGT.

                           Note: If you are surveying past midnight, the same Target File
                                  will remain open and active until you change it or exit
                                  and re-enter SURVEY.

                           To specify that the Target File be saved to a directory other than
                           the project directory, select OPTIONS-PROJECT
                           INFORMATION, check "Override Target Path" and specify the
                           alternate directory.

         A. Marking Targets in Survey
                             Targets can be marked in the SURVEY program by:
                              Selecting TARGET–QUICK MARK (or F5 key), a target
                                is marked at the current tracking point position.
                              Double clicking anywhere on the Area Map window, a
                                target is set at that position.
                              Selecting TARGET-SELECT and clicking [New] in the
                                dialog. The Target Properties dialog will appear for you to
                                enter the necessary data.
                             The name of a Target defaults to the computer clock time a
                             Target was marked.
                             Each time a target is created in SURVEY, it is saved to the
                             current Target file.

         B.Selecting Targets in Survey
                             The Area Map can display several Targets simultaneously. It
                             can also calculate the distance and bearing to a specific Target.
                             To select a Target, right-click on the desired Target and click on
                             Select. The ―Selected‖ Target is drawn with a triangle at its
                             center while other Targets are drawn with a ―plus‖ sign at their

Selection Menu.

         C.Erasing and Restoring Targets in Survey
                             You can display only selected targets from a loaded Target file
                             by "erasing" (and restoring) selected targets from the display.
                             To remove a target from the Area Map without deleting them
                             from the Target file by:
                              Right clicking on it and then clicking the "Erase" menu
                              Selecting the Target and then TARGETS-ERASE
                              Select TARGETS-ERASE ALL to erase all of the Targets
                                 from the screen.
                             The Target is still stored in the Target (*.TGT) file and can be
                             restored to the screen.
                             To restore an erased target:

                        1. Select TARGET–SELECT from the main SURVEY menu.
                           The Target Properties dialog will appear.
                        2. Click on the Target you want to affect and click [Select].
                           Survey will display all Targets that are marked with a "+" to
                           the left of the Target name.

        D.Target Properties in Survey
                        You can access the Target Properties dialog by:
                         Right-clicking on a Target and selecting the ―Properties‖

                         Selecting a Target and hitting F6.
                        You may edit the Target Properties just by typing in the new
The Target Properties

                        The Name of a Target defaults to the computer clock time a
                        Target was marked.
                        The Boat Position and Target Position can be displayed in
                        either X-Y or Lat-Long. This is changed with the OPTIONS–
                        TARGET PARAMETERS menu.
                        The Boat Position is the location of the tracking point when the
                        Target is marked using the Quickmark function. If the Target
                        was created in the Target Editor it will be the same as the Target
                        Distance and Bearing settings enable you to offset a Target
                        from the marked location. It will be displayed in the new
                        position with a line connecting it to the original position to show
                        the offset.
                        The Target Position is the actual location of the Target,
                        offsetting it by the Distance and Bearing entered from the
                        tracking point.

                              Time, Date, Event, and QUA data are saved for each Target as
                              it is created.
                              In this figure, Buoy 23 Red is the current selected target, noted
                              by the triangle in the center. Buoy 20 Green has been offset 100‘
                              at a bearing of 045 degrees. A vector is drawn from theboat
                              origin to the Target Position and the Target Circles are centered
                              about the Target Position.

                       Number of Circles draws concentric circles around the Target.
                       The Radius Increment defines the distance between the target
                       location and the first circle and the distance between each circle.
                       Making Targets does not produce Events prevents events at
                       target locations. Clear this option to produce events when
                       targets are created.

                       circle target is created. Too many target labels may clutter your
                       Alarm adds a text box display for each target with the Target
                       Name and the Distance and Bearing from the vessel‘s tracking
                       point. (Example) The text box changes color, according to the
                       alarm distances set in the Target tab of the HYPACK® Control
                       Panel. The default colors are green (low), yellow (medium
                       caution) and red (danger), but you can set your own colors using
                       the SCHEME BUILDER program.

                       Note: This Alarm setting overrides the setting in the Control
                              Panel, Targets tab.

                       If alarm flags overlap or if they are obstructing your view of
                       other critical features in your area map, you can modify the
                       positioning of the flag through the Target Properties. (Right
                       click the target whose alarm flag you want to modify, select
                       Properties and change the Orientation setting.)
                       Target file backup time saves the data to your target file and
                       evenly spaced time intervals. This protects your target data from
                       loss in the event of unexpected power interruptions. If no time
                       is entered, the file will automatically save when you exit

        F. Loading a Manually Prepared Target File in Survey
                       You can prepare a Target File in advance by using the TARGET
                       EDITOR. Once a file has been created, you can load it into the

Water's Edge Target

                         The Water's Edge option creates a special kind of target used to
                         mark the river bank when running lines perpendicular across the

                         Note: It is not accurate for use in volumes calculations. A

                         a. When you are On-Line and approaching the far bank,
                             proceed as close to the bank as possible and press the
                             F7 key (or use the menu).
                         b. Enter the Distance from the tracking point position
                             to the riverbank. The program calculates the X-Y of
                             the river bank and saves this as the last record in your
                             data file with a depth of ―0.0‖. It then closes the data file
                             and selects the next data file in the queue.

       H.Connecting Targets with Survey Lines
                      You can create a single-segmented survey line wherever you
                      need one--right in SURVEY.
                      1. Create two targets, one at each end of the line you need.
                      2. Select the Target to which you want to draw the line.
                      3. Right click on the Target that you want to draw the line
                         from and select "Line to Current". A survey line will be
                         drawn between the indicated Targets and added to the
                         currently selected Planned Line File.

       I. Connecting Targets to the Boat Position in Survey
                      If you have a planned line file enabled, you can create a survey
                      line from your tracking point position to a Target. Just right
                      click on the Target and select Line to Vessel. A survey line will
                      be drawn between the indicated Target and your vessel, and
                      added to the currently selected Planned Line File.

                      Note: This option is disabled if there is no Planned Line File

XI. Matrix Files in Survey
                      A matrix file (*.MTX) is a rectangular, gridded area which is
                      composed of thousands (or millions) of individual cells. The
                      SURVEY or DREDGEPACK® program can ―fill‖ the matrix
                      with depth information from your echosounder or cutter head.
                      Matrix files can be used to provide coverage diagrams for single
                      beam, multiple transducer and multibeam systems..

                         After the survey, they can be plotted from HYPLOT, used to
                         create a TIN model or converted to ASCII XYZ data.

         A. Loading and Unloading Matrix Files in Survey
                         If Matrix Files (*.MTX) have been specified in the HYPACK®
                         project screen, they will be automatically loaded into the
                         SURVEY program. You can also ―Load‖ and ―Unload‖ Matrix
                         Files in real time.
                         To load a Matrix File, select MATRIX-LOAD and select the
                         Matrix File from the project selection dialog.
                         If you have loaded a "filled" matrix and wish to remove the
                         sounding data, select MATRIX-CLEAR CURRENT DATA.
                         You will be given the option to save the sounding data to XYZ
                         format and the soundings will be erased from the Area Map.

                         Note: If you clear the data, you can not later use the MATRIX-
                                 SHOW ORIGINAL DATA option to compare previous
                                 data from the survey area with current ones.

                         To unload a Matrix File, select MATRIX-UNLOAD.

         B.Multiple Matrix Files in Survey
                         In certain projects, it may be advantageous to have a series of
                         smaller matrix files, rather than one huge matrix file. It is more
                         efficient for the program to concentrate on one, small matrix file
                         at a time and automatically ―swap‖ between them (depending on
                         the position of the vessel) than to have to manage and re-draw
                         one that is hundreds of megabytes in size.
                         The Preparation section of the HYPACK® manual deals with
                         creating multiple matrices.
                         The SURVEY program will load multiple matrix files. It will
                         display and update any matrix while the survey vessel falls
                         within its boundary. As it moves through the project, the

3-36 • Survey                                                                                 2/08
                           program will continue to load and un-load the individual matrix
                           files, depending on its location.
                           Note that only one matrix can display data at a time while you
                           are logging data. In the case where matrices overlap, the matrix
                           whose center is closest to the boat position will be viewable. All
                           matrices may be displayed simultaneously (complete with
                           sounding data) only when you are off line by selecting
                           MATRIX-DISPLAY ALL MATRICES.

        C.Saving Soundings to a Matrix in Survey
               1) Painting your Matrix in Survey
                           You can compare survey data of the same area from an earlier
                           survey by loading a matrix containing the earlier sounding data.
                           As you survey, the new sounding data will overwrite what was
                           previously entered.
                           Alternatively, you can erase the sounding data from the loaded
                           matrix file, then save your new soundings to the empty Matrix.
                           Select MATRIX-CLEAR CURRENT DATA. You can choose to
                           save the data to a backup matrix file in the project's backup
                           directory or just discard it..

               2) Determining the Soundings that Fill the Matrix in Survey
                           When a Matrix is loaded in SURVEY, the soundings you record
                           will be saved to the matrix according to the criteria set in the
                           Matrix Options. (Dual Frequency systems will save the Depth1
                           value—typically the high frequency sounding.) Select
                           MATRIX-OPTIONS and the Matrix Options dialog will appear.
Matrix Options Dialog

                           Record Depth determines the depth reading to be stored to each
                           Matrix Cell. Note how each is affected by Depth or Elevation
                           Mode which you have set from the Matrix menu.
                           Minimum will record the smallest depth value received in that
                            In Depth Mode, the smallest value is at the shoalest point.

2/08                                                                                Survey • 3-37
                   In Elevation Mode, the smallest value is at the deepest
                Maximum will record the largest depth value received in that
                 In Depth Mode, the largest depth is deepest, while the
                     smallest depth is shoalest.
                 In Elevation Mode, the largest depth is shoalest, while the
                     smallest depth is deepest.
                Last will record the last sounding received.
                Use Depth Filter may be used to omit soundings outside of the
                user-defined range (Min Depth to Max Depth) from being saved
                to the Matrix.
                Transparency Level allows a user-defined transparency of the
                matrix in order to see displays, such as charts, that are drawn
                beneath it. The following figures show the matrix at varying
                levels of transparency.

                    sounding value and the strike depth only where the
                    soundings are greater than the user-defined strike depth. If
                    the sounding is deeper than the strike depth, no value is
                    saved at that cell. This is useful to see how much must be
                    dredged to level the area to the strike depth.
                 Unselected, this option saves all depths.

           Beware!       This function is influenced by the Elevation Mode setting. If you are in
                         Elevation Mode, this will record depths deeper than the strike mode.
                         Probably not a very useful set of data!
                          You may also choose a Matrix Update Basis. You can choose
                          to update your Matrix as follows:
                           Always updates your Matrix continuously.
                           While Logging updates your Matrix only when you are
                              logging Raw data. Your Matrix and Survey files will

                              sounding data.
                          The Matrix is updated, by default, with corrected depth
                          information. Use Uncorrected Depths should be checked if
                          your echosounder outputs corrected depths.

              3) Editing Matrix Depths with a Border File
                          The Matrix menu has a group of selections that, together, enable
                          you to use a Border File to modify the soundings in your matrix
                          inside or outside its boundaries.

       D.Matrix Color Settings in Survey
                        The Matrix File Legend will appear along the left-hand side of the Area
                        Map when a Matrix file has been loaded. This displays the current color
                        zones used in displaying the matrix depths.
                        The Matrix File colors default to the colors set in HYPACK® Sounding
                        You can modify the colors through the Color Settings dialog by right
                        clicking on the legend and selecting Settings. The Standard Color
                        Settings dialog will appear for you to make any changes. See "Sounding

                                       and the Navigation Parameters dialog will appear.
                                    b. Enter a number, in minutes, in MTX Backup Time.
                                       This is the frequency that the program automatically
                                       saves the MTX file. If the value is 0, the program will
                                       not automatically save.
                                This provides you with a near-current copy of the MTX file that

                                Since the tide correction is normally added to the measured
                                depth, it will normally be a negative value in HYPACK® (unless
                                the tide drops below the chart datum).
                                For example, if the water level is 1.3m above the chart datum,
                                the tide correction in HYPACK® would be ―-1.3‖.
                                There are several methods to assign tide corrections to your
                                sounding data.
                                 Use a telemetry tide system.

                             Manually enter tide corrections in the SURVEY program.
                             Read predicted tides into the SURVEY program using the
                             Use an RTK Water Level driver (GPS.dll or Kinematic.dll)
                             Enter the tide correction values in post processing.
                          The Data Display window can be configured to show any or all
                          of the following:
                           Current tide correction
                           Measured depth from the echosounder
                           ―Corrected‖ depth
                          Since the Tide Correction is applied to all vessels, it is displayed
                          in Black in the Data Display window.

        A. Telemetry Tide Gauges in Survey
                          The SURVEY program treats telemetry tide gauges like another
                          piece of survey equipment. Every time it receives an update
                          from the telemetry tide gauge, it sets the Tide Correction to the
                          appropriate value. HYPACK® currently works with telemetry
                          gauges from Hazen, Vyner, and Valeport.

        B.Manual Entry of Tide Corrections in Survey
                          You can set the initial value of the tide correction by clicking the
                          TIDE–SET menu item. This value will be assigned to all
                          soundings logged until you set a new value. Update this value
                          often, especially if the tide level is changing quickly.
Setting the Tide Value

                          The Tide Increase (Alt-Y) and Tide Decrease (Alt-Z) can be
                          used to increase or decrease the current tide value by the current
                          increment. The increment is set from the OPTIONS–
                          CORRECTIONS INCREMENT menu item.
Setting the Corrections

                          Note: If you use the same time and tide correction information to
                                  create a tide correction file, then use it to apply your
                                  corrections during post-processing, your results will be
                                  more realistic. The editor will interpolate the tide

2/08                                                                                 Survey • 3-43
                                correction values over time, thus avoiding the sudden
                                changes in tide correction values.

                        The tide correction value at the time each raw file is opened will
                        be recorded in the header of the file. Each time you modify the
                        correction value, it will be recorded as a TID record and used to
                        correct soundings taken after that time.

         C.Predicted Tide Corrections in Survey
                        You may assign predicted tide values to survey data.
                         Create a predicted tide file for your area using either the
                           MANUAL TIDE program‘s High/Low Water routine or the
                           HARMONIC PREDICTION program.
                         Create a device using the TIDEFILE.DLL device driver
                           when you configure your hardware. Under ―Setup‖, select
                           the name of your predicted tide file (*.TID).
                        The SURVEY program will then assign a tide correction to each
                        sounding, based on the values in the prediction file. These
                        values can be overwritten with actual tides when processing the
                        data in the Single Beam Processing or Multibeam Processing

         D.RTK GPS Tide Corrections in Survey
                        HYPACK® can determine water level corrections (tide
                        corrections) based on the height of your GPS antenna above the
                        reference ellipsoid and the separation between the reference
                        ellipsoid and the chart datum. Details of this are contained in the
                        Utilities section of this manual.

XIII.Draft/Squat Corrections
                        When you are manually setting Draft and Squat corrections, the
                        Draft option in the Vessel Setup dialog can be used to adjust the
                        correction currently logged in the data file. This value is logged
                        in the header of every data file and every time it is changed.

                        Note: If you are using RTK tides with HYPACK you do not
                                need to enter any draft corrections.
                        The GPS.dll (formerly known as the Kinematic.dll) subtracts the
                              dynamic draft correction to compute the "true" tide
                              correction. Without a draft correction, the driver will
                              still calculate a correct chart sounding, but the RTK Tide
                              value will be different from the conventional tide value.

        A. Manual Draft/Squat Corrections
                          Define Draft/Squat corrections for each vessel in the Vessel
                          Setup dialog under "Draft".
                          Draft/Squat corrections are logged in the header of every data
                          file and every time it is changed. This value is also displayed for
                          each vessel in the Data Display using the Symbol Color
                          associated with each vessel.
                          Increase or decrease the correction value by a user-defined
                          amount using Alt+W and Alt+X respectively.

Setting the Corrections

        B.Automatic Draft/Squat Corrections
                          Automatically apply draft/squat corrections by installing the
                          Draft Table Driver in HARDWARE. The Draft Table is a
                          listing of draft correction values with their corresponding
                          vessel speeds. This option enables SURVEY to automatically
                          apply draft/squat corrections based on the speed of the vessel.
                          1.   In HARDWARE, select DEVICES-ADD DEVICE and select
                               the HYPACK Draft Table driver (DraftTable.dll).
                          2.   Check "Draft" in the Device Setup dialog.
                          3.   Click [Setup] and fill in the Draft Table, setting draft
                               correction values (in survey units) with their corresponding
                               vessel speeds (in knots).
                          4.   Close the table to return to the device setup dialog and click
                               [OK] to return to HARDWARE.

                          Note: If you are using RTK tides with HYPACK®, you do not
                                  need to enter any draft corrections.

                                   The Kinematic.dll subtracts the dynamic draft correction
                                   to compute the "true" tide correction. Without a draft
                                   correction, the driver will still calculate a correct chart
                                   sounding, but the RTK Tide value will be different from
                                   the conventional tide value.

XIV.            Shared Memory Programs
                             The Shared Memory programs enable you to display and export
                             information from the SURVEY program. These programs were
                             developed to enable you to write powerful interface drivers for
                             application programs without having to interfere with the
                             SURVEY program. These programs can be launched from the
                             OPTIONS–SHARED MEMORY menu item of SURVEY. The
                             ADCP LOGGER and 3D TERRAIN VIEWER (3DTV) are
                             described in the Utilities chapter.

                      The Shared Memory Output program is used by those who need
                      to save specific data from the HYPACK® SURVEY program out
                      the serial or parallel ports or to a file. You can select which
                      items to export from a set-up window and format the chosen
                      items according to your needs. If this program is open when you
                      close SURVEY, it will resume using the same settings the next
                      time you launch SURVEY.

                      Note: If you want to output multiple sets of data, you can launch
                              more than one incident of this module with different
                              connection settings for each.

                      1. Start the program by selecting OPTIONS-SHARED
                         MEMORY-OUTPUT. The Shared Memory Output

                           1. Select each item you wish in your export string by
                               checking its box. You can also enter up to five custom
                               strings which may then be selected when configuring your
                               Shared Memory Output.
                           2. Arrange the items in the order that they should appear in
                               the exported data string. You can reposition an item
                               relative to another by:
                                     selecting the item and using the up or down arrows
                                     selecting an item and dragging it in the list.

                2) Setting your Memory Output Options
                           The whole idea of Shared Memory Output is that you can create
                           a custom output string. There are several output options to
                            The exported data string format according to the needs of
                               the receiving computer.
                                    Lat./Lon. Options enable you to choose the format
                                       of the position information regarding degree signs

                           and the use of N/S and E/W. At this time the only
                           configuration is dd mm.mmm.
                        Invert depth option: If you are exporting depths
                           and you want to invert them, check the box.
                        Speed units: Choose knots, meters/second, or
                        Select the delimiter. Items in your output string can
                           be separated by commas or spaces.
                        Indicate what message should appear at the end
                           of the string. You have a choice of Carriage
                           Return, Line Feed or both. If none of these suits
                           your need, create one that does under Other.
                        If your device expects a checksum, check the box.
                        Enter the characters expected by your receiving
                           device for the start and end of the message. The
                           End of Message string from the second column will
                           appear immediately before the End of Message
                           selection in the first column.
                   The Send Frequency: You can send your string:
                        At each reading of any kind.
                        At each new position reading by checking the
                           Export New Position Only box.
                        Only on events by checking the On Event Only

                Note: Selecting both check boxes will result in no output.

                   Timer options offer you the choice of using the:
                         Windows® timer , which is easily interrupted by
                             certain interactions with the Windows® interface and
                             is, therefore likely to be less accurate.
                         Internal timer is probably more accurate.
                   Initialization String options enable you to configure and
                    send an initialization string if you are outputting data to a
                    recording device that first needs to be prepared in this
                    a. Enter the initialization string required by your device.
                    b. Send the string to your device. Check the Send String
                        At Startup box. This will automatically send the
                        initialization string when you start the Shared Memory

                                    will output to a text file with the *.OUT extension. The
                                    default filename will create a new, write-only file each
                                    day and the name will default to ―SMOutputDate.out‖
                                    (ex. SMOutput08042006.out). You may choose to name
                                    your own file. In this case, the program will continue to
                                    append data to that file until you change this setting.
                                 b. Provide the output information pertinent to the
                                 c. Specify the Update Frequency (msec).
                                 d. Click [OK] to return to the Shared Memory Output

               3) Broadcasting Survey Data over the Network
                             If you save your Shared Memory Output settings to an .ini file
                             and export your Shared Memory Output to the network, any
                             network computer, including your own, can use the Shared
                             Memory Input device driver (SMInput.dll) to read the data

2/08                                                                                   Survey • 3-51
                           This requires that both computers have licensed versions of
                           HYPACK® that can run SURVEY and the hardlock that goes
                           with it.
                           In this way you can run another incident of SURVEY, but read
                           the data from Shared Memory instead of the devices themselves.

         C.Echosounder Display
                           The Echosounder Display enables you to configure and view a
                           graph of the depth soundings in real time during SURVEY.

                1) Running Echosounder Display
                           1. Start the program by selecting OPTIONS-SHARED
                              MEMORY-ECHOSOUNDER DISPLAY. The
                              Echosounder Display window will appear. The left side of
                              the screen graphs your soundings in real time.

                           2. Set your display options.
                           3. Click [Exit] to close the Echosounder Display.
                           To print a screen capture, select FILE-PRINT. This accesses
                           the standard Windows® print window.

                2) Echosounder Display Options
                           To configure your chart select FILE-SETTINGS. A tabbed
                           dialog will appear.

       Chart Display Options

                               Automatic Scaling automatically adjusts the scale of the graph
                               to fit the depth readings.
                               Manual Scaling allows you to choose the minimum and
                               maximum depths of the graph.
                               Gradation adjusts the distance between the graph lines.
                               Trace Width adjusts the width of the sounding lines.
                               Chart Speed determines the rate the chart scrolls.
                               To modify colors and fonts in the display, select FILE-
                               SETTINGS and select the Colors Tab. Click on the button
                               corresponding to the feature color you want to change. The
                               Windows® colors dialog will appear for you to make your
                               If you have multiple vessels, you can select the which vessel's
                               data is displayed by selecting it in the FILE-SETTINGS-Options
                               Tab. With this feature, you can display data from multiple
                               vessels by launching an Echosounder Display for each vessel to
                               be viewed and choosing a different vessel for each display.

       D.NMEA Output
                               NMEA Output enables you to export user-defined NMEA strings
                               from the SURVEY program. It can be used together with the
                               NetNMEA.dll to broadcast the output strings over the network.
                               If you want to output multiple sets of data, you can launch more
                               than one incident of this module with different connection
                               settings for each. If this program is open when you close
                               SURVEY, it will resume using the same settings the next time
                               you launch SURVEY.
                               1. Select OPTIONS-SHARED MEMORY-NMEA

2/08                                                                                     Survey • 3-53

                       2. Select which NMEA strings to export. Checking the
                          WGS84 option tells it to output WGS84 rather than local
                       3. Define the Update Rate (the frequency to send messages).
                       4. Define the Prefix. This is typically GP, but can be
                       5. Set the connection information by clicking [Connect] and
                          filling in the dialog (as in HARDWARE).
                       6. If you plan on using multiple instances of NMEA OUTPUT,
                          save each series of settings to a named file. In this way
                          you can remember the settings for each instance by a name.
                          Click [Settings] and provide a name. The settings will be
                          saved. They can be recalled by clicking [Load Settings] and
                          selecting the name from the drop down menu.
                       7. Click [Start]. You can preview the output in the bottom of
                          the screen or click on [Hide Screen] to remove this display.

                       Note: The [Start] key changes to [Pause] when the program is
                              exporting data. You can toggle the export of data on and
                              off with this button.

         E. Odometer
                       The Odometer program enables you to monitor the distance
                       traveled. This is only for on-screen viewing; there is no data
                       output. The program allows you to view up to 3 different

                          2. Select the distance units.
                          3. Specify distance to measure, all travel or only the distance
                             traveled while surveying.
                          4. Check the Active check box and view the distances in the
                             windows on the left. Toggle this measurement on and off
                             manually by checking and clearing the box.

       F. Graphical Motion Reference Unit
                          The Graphical MRU program shows Heading, Pitch and Roll in

XV. Logging Data in Survey
         A. Navigating Planned Lines in Survey
                            Since you took the effort to create Planned Lines to guide your
                            survey vessel, it might be a good idea to learn how to follow the
                            lines you've created and collect survey data. The following
                            sections describe how to manually or automatically choose the
                            line you want to survey and how to determine when data will be
                            logged to your hard drive.

                1) Selecting Survey Lines in Survey
                            The active planned line in your project will be loaded to the
                            SURVEY program. You can load a different Line File by
                            selecting LINE-SELECT and choosing the new Line File from
                            the file selection dialog. SURVEY will unload any active Line
                            File and load the selected file. Only one Planned Line File may
                            be enabled at a time. (You can unload any active Line File and
                            work with no lines loaded by selecting LINE-UNLOAD.)
                            When you first enter the SURVEY program, it will select the
                            first line in the queue as the current active line. When you exit
                            the SURVEY program, it writes the current active line to a
                            default file. When you re-start the SURVEY program, it reads
                            this default file and re-establishes the last active line as the
                            current active line.
                            You can select the line you wish to survey using one of the
                            following methods.

                               Right click on a line handle and then click the “Select”
                                item. The ―handles‖ are located at each line origin (the first
                                point entered when creating the line) and are drawn as little
                                boxes at the origin of a planned line.
Selecting a line using

                               Use the LINE–INCREMENT LINE menu item or Ctrl-I
                                to move ahead by the number of lines defined under Line
                                Increment in the Navigation Parameters.
                               Use the LINE–DECREMENT LINE menu item or Ctrl-D
                                to move back by the number of lines defined under Line
                                Increment in the Navigation Parameters.
                               Enter the desired line number under Next Line in the
                                Navigation Parameters. You may enter either the number
                                or name (―34+00‖) associated with a line.

                 2) Changing Survey Direction in Survey
                            When you select a new planned line or when the SURVEY
                            program selects a new planned line, it sets the ―Start Line‖ end
                            according to the Line Direction Mode in Navigation Parameters,
                            and assumes you will be running the line from that end to the far
                            end. It draws a red circle about the ―Start Line‖ end (when off-
                            line) to show you which end it has selected as the ―Start Line‖
                            end. It also superimposes a series of arrows along the line to
                            indicate the expected direction of travel.

2/08                                                                                  Survey • 3-57
                               Line Direction Mode tells SURVEY the pattern the survey
                                vessel will normally follow when a new planned line is
                                     Closest looks for the end of the line closest to the
                                        vessel and assumes you want to run the line starting
                                        from that end.
                                     Line Origin starts the line at the first set of
                                        coordinates for the line in the Planned Line File.
                                        This is useful for surveyors who want to run all of
                                        their lines in the same direction.
                                     Line Terminus starts the line at the last set of
                                        coordinates for the line in the Planned Line File.
                                        This is useful for surveyors who want to run all of
                                        their lines in the same direction.
                                     Alternate Direction starts the next line in the
                                        opposite direction from the direction of current one
                                        based on the coordinates entered in the Planned Line
                                        File. (Alternates Origin-to-Terminus, then Terminus
                                        to Origin.)
                            To change the selection of the “Start Line” end, ―Swap‖ the
                            line ends. You can do this by:
                             Selecting LINE-SWAP.
                             Right clicking on the line handle and clicking “Swap”.
                             Selecting the line and pressing Ctrl + W.

                3) Starting Line in Survey
                            When you ―Start Line‖, the SURVEY program opens up a data
                            file and begins to record data. You can start line:
                             Manually by selecting Logging–Start Logging (Ctrl+S)
                             Automatically using the automatic Start Line Gate feature.
                            When you ―Start Line‖, the Status in the Data Display window
                            will change to Logging. This is your indication that you have
                            started line and the SURVEY program is logging data.

                            The automated Start Line Gate feature enables you to go ―On
                            Line‖ automatically if the tracking point gets within the specified
                            distance of the start line point.
                            The Start Line Gate is specified in the Navigation Parameters
                            window. Select OPTIONS–NAVIGATION PARAMETERS.

Navigation Parameters

                            If the Start Line Gate is set to “0.0”, the feature is disabled and
                            the SURVEY program will only ―Start Line‖ and ―End Line‖ if
                            you manually intervene.
                            If the Start Line Gate is set to a value other than zero, the
                            program will start line automatically when the distance from the
                            tracking point to the starting point of the planned line is less than
                            the absolute value of the Start Line Gate.
                            If a negative value is specified for the Start Line Gate, the
                            SURVEY program will only go ―On Line‖ when the tracking
                            point breaks the perpendicular projection of the start line point
                            and the distance from the tracking point to the starting point of
                            the planned line is less than the absolute value of the Start Line

                 5) Ending Line in Survey
                            Once a planned line has been started, it can be ended:
                             Manually by selecting the Logging–End Logging (or
                             Automatically if you are using the Start Line Gate. The line
                               will be ended automatically when the tracking point breaks
                               the a line projected perpendicular from the end segment
                               point of the planned line.
                            When the SURVEY program executes an ―End Line‖, it closes
                            and saves the data file and then selects the next line in the line
                            queue. It determines the Start Line point based on the Line
                            Mode. A small red circle is drawn about the start line point and
                            arrows indicate the direction of travel.

2/08                                                                                    Survey • 3-59
                6) Adding New Lines in Survey
                           Surveyors can create a new planned line in SURVEY by
                           specifying a parallel offset from an existing planned line.
                           Select LINE-ADD and the Add New Line dialog will appear.
                           This example, tells SURVEY to create a new line named ―33‖.
                           This line will be created 15‘ (or meters, according to the current
                           grid units) from line number ―1‖. Positive offset values create
                           lines to the right of the ―Base Line‖ when you stand at point 1 of
                           the base line and look at point 2. The new line created is saved
                           to the LNW file and becomes a permanent line in the planned
                           line file.
Add New Line Window

                7) Closing Data Files based on Time in Survey
                           For surveys of long survey lines, you can instruct the SURVEY
                           program to automatically close the current data file and open a
                           new data file without changing the current line.
                           Select OPTIONS–NAVIGATION PARAMETERS and enter a
                           non-zero value in the ―Log Backup Time‖. The value entered
                           represents the number of minutes elapsed before closing the
                           current data file and opening a new file. New files that are
                           opened using this feature are named using the conventional
                           naming scheme for data files which eliminates duplicate file
                           For example, say your planned line would take four hours to
                           survey and you have entered ―15‖ as the Log Backup Time.
                           Every 15 minutes, SURVEY would close the current Raw data
                           file and open a new data file. This would result in 16 data files
                           for the planned line.

                8) Selecting Segments on Multiple Segment Lines in Survey
                           This is used by SURVEY to determine how to step through
                           multiple segment planned lines.
                           Select OPTIONS–NAVIGATION PARAMETERS. The
                           available choices are:
                            While Logging: Using this method, the current segment is
                               fixed until the program goes ―On Line‖. It then

3-60 • Survey                                                                                   2/08
                           automatically switches to the closest segment, based on the
                           off-line distance of each segment.
                          Always: This method constantly updates to the most
                           appropriate segment, whether the program is ―On Line‖ or
                           ―Off Line‖.
                          Never: This will not change the current segment. You may
                           manually change segments using the Ctrl-F (Forward
                           Segment) or Ctrl-B (Backward Segment) key commands.

       B.Logging Events in Survey
                       Event marks are also called ―Fix Marks‖. They are used to mark
                       recorders to allow you to correlate digital (HYPACK®) and
                       analog records. Include the beep.dll in your hardware setup to
                       sound a user-defined tone each time an event mark is created.
                       The Next Event item in the Navigation Parameters sets the
                       number of the next event mark. The SURVEY program
                       ―remembers‖ the last event number when it is shut down and,
                       when restarted, will begin numbering event marks at the last

            1) Automatic Logging of Events in Survey
                       Event Marks are always generated when you pass a waypoint
                       (switch legs) in your survey line.
                       Event Marks can also be automatically generated based on time
                       or distance along line. Select OPTIONS–NAVIGATION
                       PARAMETER and choose the Event Basis.
                        If you select "Time", the Event Increment is expressed in
                        If you select "Distance", it is the distance in survey grid
                           units (feet or meters) between events.

                       Note: HYPACK® does not predict when your survey vessel
                              passes over precise fix locations. It simply generates a
                              fix mark at the first position update which is equal to or
                              farther down-line from the pre-defined event location

            2) Suspend/Resume Logging in Survey
                       To suspend logging at any time while ―On-Line‖, select
                       LOGGING-SUSPEND LOGGING. The Status in the Data
                       Display window will display the word ―Suspended‖. A target
                       with the name ―Paused‖ will be placed on the screen at the
                       tracking point position. You will still receive screen updates and
                       position information, but the program will not write information
                       to disk. This is useful if the survey boat needs to pause for
                       To resume logging, select LOGGING-RESUME LOGGING.

2/08                                                                            Survey • 3-61
                3) Manual Logging of Events in Survey
                           You can generate a manual event mark at any time by pressing
                           the Ctrl-N key command or by clicking the LOGGING–
                           MANUAL EVENT menu item.

         C.Logging Seabed Identification Data in Survey
                           The SeabedID device driver should be used for all bottom
                           classification surveys. It requires that:
                            Your echosounder outputs the E1 and E2 soundings
                               necessary to distinguish between varying bottom types.
                            You have a Seabed Square for the bottom types in your
                               survey area. This is a user-defined table of E1-E2 ranges
                               with their corresponding bottom types and ID numbers. It is
                               created in the SEABED STATISTICS utility program. (See
                               Seabed Statistics in the Utilities chapter of this manual.)
                            You have saved your seabed colors represented in your
                               Seabed Square as your project colors. When you create
                               your Seabed Square in SEABED STATISTICS, the program
                               will ask if you would like to create a corresponding
                               HYPACK Color File (*.HCF) and make it the current
                               project color file. Click ―Yes‖.
                           During SURVEY, the SeabedID device driver refers to the
                           Seabed Square to assign a Seabed ID number for each sounding
                           record. It saves the E1-E2 pairs with their assigned numbers to
                           ROX strings in the Raw data files.
                           The SeabedID driver has two device windows for each data
                           channel. One shows your Seabed Square with a dynamic display
                           of the most recent 500 soundings overlaid where they fell within
                           the square. The other graphs depths over time.

                       Since the ID numbers are assigned in real-time, In addition to the
                       device windows, SURVEY can paint the matrix using seabed
                       classification colors. This requires certain settings working
                       1. Create the Seabed Square for your survey area.
                       2. In the SeabedID driver setup:
                                 Select the ‗Use for Matrix Update‘ option
                                 Designate your Seabed Square.
                       3. In SURVEY’s Matrix menu, select the Seabed ID option.
                       This matrix will also display in HYPACK® using seabed colors.
                       Just right click on the matrix folder in the Project Files list and
                       select either ‗Survey Depth‘ or ‗Seabed ID‘.

XVI.          Plotting in Survey
                       You can to plot track lines, or soundings, or both to an HP/GL–
                       language plotter while on-line.
                       1. In the HARDWARE program, select the HPGL.DLL
                           device driver. This is the driver than generates code to the
                           plotter. In the Connect dialog, specify how the plotter is
                           connected (COM port or LPT port).
                       2. Make a plotting sheet before you begin the SURVEY
                           program. See the details regarding plotting sheets (*.PLT
                           files) in the Preparation chapter of this manual.
                       3. Begin the SURVEY program, a configuration dialog will

                        9. When your plotter is ready, click [Start]. The driver will
                           begin to send plotter code to your plotter, based on your
                           settings. At any time, you may stop the plot by clicking
                           [STOP] button.
                        If you wish to plot on a new piece of paper, click [Stop].
                        Insert your paper in the plotter. Go through the Plot Border, Plot
                        Lines and Label Lines options. Then click [Start] and you are
                        back plotting on the new sheet.

XVII.          Printing Survey Data
                        You can print survey data while online to any printer. The
                        location of the printer is specified under the Device menu of the
                        HARDWARE program. The message to be printed is defined in
                        the SURVEY program.
                        1. Select LOGGING–PRINT–CONFIGURE. The Printer
                            Configuration window, shown in the following figure, will

                        2. Move items you want to have printed from the Available
                           list to the Printed list in the order you want them printed.
                           You can move an item by clicking on an item in the
                           Available list and then clicking [Add->] or by double
                           clicking on the item in the Available list.
                        3. Enter the number of characters you want to reserve for
                           each item in the Printed list. Click on the item, then enter
                           a value in the Width box. Click [Apply Width]. You can
                           see the actual message constructed beneath the list windows.

                        Note: Take care that your printer message does not exceed 80

                        Print Basis: You can elect to have your message printed based
                        on distance, time or events. In most operations, you should
