         Why a New Viewer?
• To display DEP’s most up-to-date spatial
  data
• To replace ECO, which will be
  discontinued on March 12, 2010
• To display data that may not be
  included in the new SIMS viewer

Components of the Viewer




                           6
     Three Major Differences Between
           ECO and Envirodata
• No Map Redraw Button
      The map redraws EVERY TIME you turn a
      layer on or off.
 • Grayed Out Layers
       The layers are grayed out and cannot be
       turned on until you zoom in to the proper
       scale.
  • No Environmental Conditions Report
        in Envirodata. If you need this type of
        report, use the SIMS Viewer.               7
 No Map Redraw Button

To minimize redrawing
time, turn the category
off before turning new
layers on or off.

This will stop the redraw
until you check the
category name back on.

                            8
 Grayed Out Layers
Layers are grayed out
until the proper
display scale is
reached.

The check mark will
disappear at that
point and allow you to
turn the layer on.

                         9
 No Environmental Conditions Report
There is no
Environmental
Conditions
Report in
Envirodata as
there was in
ECO.

                Navigation Tools


Zoom In, Zoom Out, and Pan

   Use the mouse button to “click,
   drag and release” to zoom to a
   specific area.
              Or
   Just click on the map after
   activating the zoom tools.
            Or
   Use the on-screen pan and
   zoom tools
                                     11
                 Navigation Tools


Full Extent, Back Extent, Forward Extent

These tools are self explanatory and require only a click
directly on the tool to cause a change in your map view.
Be aware that the extent buttons do not show previous
layers that were turned on, merely your current layers in
the old extent.


                Full
                Extent
                Example
                                                            12
               Window Magnifier Tool


Magnifier Window

Allows you to
magnify a chosen
area without
changing your
map scale.

Magnify your area
from 2 times to 10
times larger.

                       Identify Tool


The Identify Tool will give you information about the features
that are visible on your map.
                                            • First, click the
                                              point on the map
                                              that you would like
                                              to identify.

                                           • Click the arrow
                                             beside the first
                                             layer name to see
                                             a complete list of
                                             layers that were
                                             identified.      14
Identify Tool


          • To view the identify
            results for that layer,
            click on the layer name.
          • You now have the
            option of adding this
            information to the
            Results area on the
            Console where you
            may print the results
            with your map, or right
            click in the Results area
            and choose Print to
            print only the results. 15
                     Measure Tool


The measure tool allows you to measure distances and
areas and to find the coordinates of a specific point.

 To measure a distance, click on the line icon.
 To measure an area, click on the polygon icon.
 To find the coordinates of a point, click on the point
 icon.

       view is located.

       Click to turn it on and Click
       again to turn it off.

                     Find Address
This tool allows you to navigate to a specific address or a
street. Click on the tool. Then type in a street address or
just the street name, followed by the type of roadway, i.e.
“Rd.”, “Ave.”, “Blvd”, etc.

                                        In this dialog box,
                                        although it offers
                                        “Intersection” as an
                                        option, this is not
                                        available. Also,
                                        beside the word

                      Find Address
Typing in “79 Elm St.” and “Hartford” displays a list of
address beginning with number 79.

                               To zoom to the list of
                               addresses, right click on one

                               To show only a selection of
                               these addresses on the map,
                               uncheck the appropriate
                               boxes.



                                                               19
                     Find Address
After zooming to the cluster of addresses in the list, each
represented by a red push pin, you can hover over a pin
and it will display the address.




                                                              20
                      Find Town
This tool finds and zooms or pans to a specific town. You
must choose a town from the list provided. You cannot find
village names, borough names, etc. For example,
Kensington would not be a choice, but Berlin would be a
choice.




                                                         21
                       Find Town
After clicking on “Find”, the

your map view and the town
result will be placed in the
“Results” section of the
Console.




      Right click on the town name
      and choose zoom to or pan
      to. This will place the entire
      town in your map view.
                                       22
                    Find Town
Now, when you hover over your town, it turns red and is
labeled with the town name.




                                                          23
                    Find Town
At any time, you can remove your town from the Results
section by right clicking on the result and choosing
“Remove”.




                                                         24
                      Printing Your Map
  Select Print. The following dialog box appears.

Your choices are:

• Title your map

• Choose a size for your map

• Choose to print Identify
  results with your map

  Identify results with no map




                                                    25
                      About the Layers
Drawing Order

The layers draw from the bottom up. Make sure that you do
not have one polygon layer drawn on top of another. Only
the top layer will be displayed.

Example: Although
both the orthos and
the topos are
turned on, only the
orthos will be
visible since they
are on top of the
topos.

                                                        26
                   About the Layers
Categories

The layers are organized into
categories so that related data are
logically placed together.

In addition, for some categories, the
layers are mutually exclusive. That
is, only one layer within a category
should be turned on at once.

These categories include:
Administrative Boundary Index,
Watershed, Geology and Soils, and
Imagery and Topos.
                                        27
                  About the Layers
Overlapping Features

For some categories,
there may be layers
that have overlapping
features. For
example, DEP
property features are
also contained in
Protected Open
Space. This means
that those two layers
may have some
overlapping features.

                                     28
                   About the Layers
Overlapping Features

Examples of other categories that have overlapping layer
features are:

• Waterbody (All Waterbody and Hydrography)

• Water Resource Management (Assessed Waterbody 2006
  and 2008)

• Geology and Soils (Soils, Wetland, Farmland, Septic
  Potential, etc.)


                                                           29
                    Thematic Maps
•   In Envirodata, Thematic Maps must be created by the
    user, unlike in ECO where Thematic Maps are already
    made for you.

•   A list of suggested layers you might use to create
    thematic maps is shown on the next slide.

•   You can also visit GIS Home on Inside DEP and choose
    List of Datalayers Available in DEP.

•   Turn the appropriate layers on and off to create your
    customized map.

•   Thematic Maps and Favorite Locations cannot be saved
    in Envirodata.                                     30
