If you select any system other than Lat/Lon or UTM,
you are asked to choose a scaling factor for displaying
position coordinates: 1 meter, 10 meters or 100
meters. If you choose 1 meter, a northing coordinate
will be displayed as, for example, 249143N. If you
chose the 10-meter factor, the same coordinate will be
displayed as 24914N. And if you select the 100-meter
factor, the coordinate will be displayed as 2491N.
-
For some systems, you are asked to supply information
on grid zones or types
-
For the User Grid, you are asked to supply a projection
type (Transverse Mercator, Lambert Conic, Stereo-
graphic, Oblique Mercator or Polyconic), coordinates
of origin, scale factor, unit to meters conversion and
false Easting and Northing at origin
Notes on Coordinate Systems:
-
The handheld always uses the WGS 84 coordinates to
locate the features and waypoints on the Map screen, even
if you select some other coordinate system/datum.
-
The coordinate systems and datums used to display any-
thing on the Map screen are only for display. When you
select some other coordinate system/datum, only the num-
bers of the coordinates of a feature/waypoint are changed.
The map screen is not changed in appearance.
