How Do You Use a GPS?

     Each brand of GPS is set
      up differently.

     At the Smith Center, we
      use Garmin etrex units.

The GPS receiver displays pages with separate
 functions.
     There are four main pages that you will be using to
      navigate:
          GPS –      Global Positioning System

Let’s Get Started!

   All GPS receivers operate on information gathered from
    satellites. In order to receive the satellite signals,
    you must be outside, away from any objects such as
    trees or overhangs that might block the signal. You
    need a clear view of the sky.

Step 1: Push and hold
down the POWER
BUTTON to turn the unit
on. You’ll see the
“Welcome” page for a few
seconds, followed by the
Satellite Page.

How do I know I’m ready
 to go?
   When you see the “Ready to
    Navigate” message, you know
    the etrex has locked onto
    the satellite signal.
   This must be displayed
    before you can begin using
    the GPS to navigate.
   Signal strength bar will be
    filled in to indicate the GPS
    has locked onto signal.

Satellite Page Basics:
   Two display pages:
    Normal Skyview that
    shows the satellites,
    satellite signal strength,
    and estimated accuracy.
    Advanced Skyview that
    shows you the numbered
    satellites being used, the
    proximity and horizon and
    sky overhead.

NAVIGATION PAGE
 BASICS
   The Navigation Page guides
    you to your destination. It
    shows you your moving
    direction and speed. If you
    have a specific destination
    entered into the GPS, the
    page shows you the name of
    the location, the distance
    and displays a direction
    arrow that is shown in the
    compass ring.

NAVIGATION PAGE BASICS:

We’ll be using LATITUDE and LONGITUDE
 coordinates to describe locations.

Latitude measures distances North or South from
  the Equator (0°) towards the Poles. (90°)

                     The units that we will be
                     using to measure are:
                        Degrees (°)

North 39° 06 .582’      Minutes ( ‘ )
                         And . . .
West 77° 06 .086’       THOUSANDTHS of
                        Minutes!

MAIN MENU BASICS:

   With the main menu you
    can create waypoints,
    routes, save and view
    your track logs. If you
    select MARK, you can
    mark your location as a
    waypoint.
       GPS –       Global Positioning System
GOING TO A WAYPOINT:
 Press the PAGE button and switch
  to the MENU Page
 Press UP or DOWN and highlight
  WAYPOINTS. Press ENTER..
 Press the UP or DOWN button
  and highlight the alphabetical tab
  for the waypoint. Press ENTER.
 This will take you to a list of
  waypoints.
 Highlight a waypoint, and press
  ENTER.
         GPS –     Global Positioning System

   REVIEW WAYPOINT
    page appears. REVIEW
    WAYPOINT allows you to
    change coordinates,
    name, symbols, and
    delete waypoints.
   On the REVIEW
    WAYPOINT page, press
    the UP or DOWN button
    and highlight GOTO,
    press enter.

 GPS technology allows us to identify locations
  of specific areas based on absolute location
 Useful in finding an area not a specific point
 Latitude and longitude coordinates are given for
  each potential settlement location

GOING TO A WAYPOINT


                   It would be VERY
                   difficult to use the GPS
                   Unit by itself to find your
                   way to your waypoint, so
                   you will also need to know
                   how to use. . .

                A Map!

                Use the map to look for
                  landmarks, to stay on
                  trails, to gauge
                  distances, and to find
                  your way back!
          GPS –       Global Positioning System

STEPS TO USING THE GPS:
   From the SATELITE page, press the PAGE button until
    you come to the MENU page.
   Scroll down to WAYPOINTS, press ENTER.
   Scroll down to the waypoint you wish to find. Press
    ENTER.
   The REVIEW WAYPOINT screen will appear, select GO
    TO, the COMPASS page will appear.
   Begin walking. The arrow will reorient in the direction
    you should be walking if you could walk a straight line to
    your waypoint. You WILL need to adjust your line of
    travel to avoid obstacles and to remain on trails.

STEPS TO LOCATING THE Patterns of
 Settlement Sites (PSSC #):

 Follow the arrow and stay on trails to find
  desired coordinates. Remember that the GPS is
  only accurate within 10 meters. When close you
  need to begin looking for the location clues.
 At this point, you will need to spread your
  group out and look around the area.
       GPS –      Global Positioning System

ONCE YOU’VE FOUND THE Site:


 Observe the surrounding area for natural
  advantages and natural resources.
 Discuss advantages and disadvantages of this
  location
 Fill in the graphic organizer with as much detail
  as possible
 Continue to the next Site
Patterns Of Settlement



    Where oh where should my little
           lamb grow - up?
Where oh where should my
 little “children” grow - up?
       The Big Questions:
   * Why do people settle in certain
      locations?
   * How does geography affect
     human settlement?
   * How do civilizations adapt to
     their environment?
           Think Survival
 What   do I NEED?
          Think Avoidance
 What   do I NEED to AVOID?
          Think Progress
 Whatwill help my civilization advance and grow
 powerful?
        Think Government
 How will I manage, control, inspire, lead,
 support… the people living with me?
           Think Economy
 How   will I make money and grow wealthy?
           Think Culture
What   do I want to do for fun?

How will my life have purpose and
 meaning?
        IN CONCLUSION
        Where shall I live?
            (Or start my civilization)
 Which   location is best suited to settle at?
  Please list at least 3 reasons why it is the
  best place.
 Please list at least 3 reasons why the other
  places you visited would not be as
  suitable for development.

THINGS TO KEEP IN MIND:

   Do not cross roads (except Meadowside Lane).
   Stay on trails as much as possible.
   You may need to go around rocks or cross streams.
   Stay together – do not leave your group.
   Use your map and compass in conjunction with the GPS.
   Respect the park! Take only your memories, leave only
    your footprints.
          GPS –       Global Positioning System

   IMPORTANT POINTS:

   GPS technology is limited – tree canopy and cloud cover
    affect signal strength
   Be aware of your direction of travel. Use a map.
   Watch the time! Return on
   time!
