Location Sub Tab

Refer to the “Appendix” of this guide for more information about location formats and map datums. Also visit the National Imagery and Mapping Agency at http://www.nima.mil for more information on grids and datums.

Location Format Sub Tab

Changing the Location Format coordinates the system in which a given location reading is shown. The default format is latitude and longitude in degrees, minutes, and thousandths of a minute (hddd°mm.mmm).

Map Datum Sub Tab

Datums are used to describe geographic locations for surveying, mapping, and navigation and are not actual maps built in the unit. The default setting is WGS 84. The unit automatically chooses the best datum based on your chosen position format.

WARNING: Selecting the wrong map datum can result in substantial location errors. You should only change the position format if you are using a map or chart that specifies a different position format or map datum or want to use a format you are familiar with. When in doubt, use the default WGS 84 datum for best overall performance.
