UTM's are marked on USGS topographic charts. This system divides
the Earth into 60 zones, each 6 degrees wide in longitude.
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,
and Greek grid systems are the national coordinate system used only in
their respective countries. In order to use these grid systems, you must
be in the respective country.
This unit will pick the matching datum for you when you select the
grid. See the entry on Map Datum Selection for more information.
The military grid reference system (MGRS) uses two grid-lettering
schemes, referred to as standard and alternate MGRS on this unit.
Your position and datum in use determines which one to use. If you use
standard, and your position is off significantly, then try the alternate
MGRS.
NOTE:
When the position format is changed, it affects the way all positions
are shown on all screens. This includes waypoints.
