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.
GPS – Global Positioning System
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°)

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.

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. . .
GPS – Global Positioning System
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.

ONCE YOU’VE FOUND THE Site:
Observe the surrounding area for natural advantages and natural resources.
Discuss advantages and disadvantages of this location

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 What will 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 CultureWhat do I want to do for fun?
How will my life have purpose and meaning?
IN CONCLUSIONWhere 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.

IMPORTANT POINTS:
GPS technology is limited – tree canopy and cloud cover affect signal strength
Be aware of your direction of travel. Use a map.
