How
do I use GPS to find my way?
This document does
not contain information for operating specific GPS units.
Instead, it will provide examples for uses of GPS in the
outdoors.
There are two general
ways that GPS can help you find your way:
| |
| 1.
GPS can help you pinpoint your exact location on
any map which is marked with the UTM grid. |
| |
Example:
Bob wants to know where he is on the map. He
turns his GPS on and after a few minutes, the GPS
unit shows Bob his UTM coordinates. Bob can then
look for the UTM markings on the map to plot his
location.
|
|
|
| |
| 2.
GPS can bring you to a specific location when you
know the coordinates, even if you don't have a
map. |
| |
Example:
Sue needs Bob to come
to her location. Sue tells Bob what her
coordinates are via radio or cell phone. Bob
enters the coordinates into his GPS unit and
presses the GOTO button. Bob's GPS is now
pointing towards Sue. It also shows the distance
to Sue "as the crow flies". Bob follows
the arrow until he can see Sue.
