Map Datum - Offers a selection of nearly all map datums in common use.  Every map is based 
on a map datum (a reference model of the earth’s shape) and is usually listed in the title block 
of the map.  If you are comparing GPS coordinates to a paper map, chart, or other reference, 
the map datum in this field must match the horizontal map datum used to generate the map 
or other reference.  The default datum is WGS-84 (World Geodetic Survey 1984) and should 
only be changed when using maps or charts specifying a different datum.  If a map does specify 
a datum, use the options list to find datums applicable to the region of the map, selecting the 
one that provides the best positioning at a known point.  If necessary, you also may choose the 
‘User’ datum for custom designed grids.

The ‘User’ datum is based on a WGS-84-Local datum and is an advanced 

feature for unlisted or custom datums.  To learn more, check your local library or the 
Internet for educational materials on datums and coordinate systems.
