Coordinate System; Map Datum - Magellan Map 410 User Manual

Coordinate System

A Coordinate System is provided for you. This option allows you to select
primary and secondary coordinates used for entering and viewing position
information. The most common is LAT/LON. You can choose from LAT/
LON, TD, UTM, OSGB, IRISH, SWISS, SWEDISH, FINNISH, FRENCH,
GERMAN, MGRS and USER GRID. The default primary coordinate
system will be Lat/Lon in Degrees/Minutes and the default secondary
coordinate system will be UTM.

If a format is required for the coordinate system you have
chosen, a pop-up menu will be displayed. Highlight your
selection and press ENTER.
You would generally want the receiver to use position coordinates in the
same map datum that is used by your maps. For example, the Irish Grid
uses the Irish datum, Finnish Grid uses the KKJ datum, Swedish Grid
uses the RT 90 datum and the Swiss Grid uses the Swiss datum.

Map Datum

You can change the datum the receiver uses to compute position coordinates.
You will want your receiver's datum to match the datum on the map or chart
you are using. Use the map "legend" to determine the datum required for
the map or chart. If you are not using a map or chart or are unsure which
datum to use, select WGS84 (the default setting).
