EXAMPLE 1:
The coordinates on the form are in UTM format; you need to make the settings in the unit
reflect the “UTM/UPS” position format before you enter the coordinates. Go to MENU/SETUP/
UNITS according to the “Check/Adjust Settings” instructions above. Highlight the “POSITION
FRMT” box and select “UTM/UPS” as described in these instructions. The UTM format usually
requires a unique datum called “NAD83,” so highlight the “MAP DATUM” box and select “NAD83.”
•
From the
MENU
screen choose “
MARK
.”
•
Scroll down until the reading at the bottom is highlighted, press
ENTER
•
Highlight each digit in the coordinate number by scrolling with the
UP/DOWN
button
•
Press
ENTER
at the number you wish to change.
•
Scroll up or down to the number you want to replace it with.
•
Press
ENTER
to change the number.
•
Scroll to the next number you want to change, repeat. Go through all the numbers, changing those you
wish to change.
•
Once finished, scroll down to
OK
.
•
Press
ENTER
when
OK
is highlighted. This will be your waypoint. Write down the title of the
waypoint you created (the number next to the flag), so you can go back to it.
•
When you are finished, simply get out of the Edit Location screen by pressing
PAGE
. You’ve created a
waypoint for your coordinates! Go onto the next section.
PLEASE NOTE:
When entering UTM/UPS coordinates, the first two digits are “1” and “6”.
Do not change this
as
this represents “16”, the standard UTM zone for Illinois. The actual coordinates starts after the “ T ”.
Tracking Back to an Existing Waypoint (i.e. a waypoint you
created):
•
Press
PAGE
button to bring up
MENU
page
•
Highlight
WAYPOINTS
and press
ENTER
(you are now in Waypoint Page)
•
Select a tab (using
UP/DOWN
) containing the number (or first letter) of the waypoint you are looking
for and press
ENTER
•
Select the waypoint that you are looking for and press
ENTER
•
Press
UP/DOWN
button to select “
GOTO
” and press
ENTER
•
The Compass Page appears and you are now ready to be guided back to your starting location. The # of
meters shown above is the distance to your waypoint.
The GPS Compass will start moving as you start moving toward your waypoint,
but it does not function in the
same way as a conventional compass
.
It is not sensitive enough to detect which direction you are facing
initially so the arrow points in the appropriate cardinal direction but doesn’t change with respect to the direction
you are facing. For this reason,
use an actual compass to tell you which direction is which before you begin
.
EXAMPLE 2: Looking at the compass screen on the GPS unit, I can see that the arrow is pointing straight at
the “N” on the screen with a distance of 6.66 m, indicating that I need to walk 6.66 m due North to find
my plant. However, when I look at my own compass, I realize that I am facing South. Therefore, first I
adjust my direction by referring to my actual compass and turn to face North. Then I refer to the GPS
compass screen.
Please do not change the setting of the GPS unit without following the directions above. If you are creating a
waypoint to be used to locate a population and the last reading is in UTM (used in 2003) we can help you
convert this into LAT/LONG so that you can enter a waypoint. Don’t fret, it’s not hard. With any questions
please contact the POC Research Assistant: call 847-835-6856 weekdays during business hours.
