Basemap

Definition: A basemap is a basic set of map data that is included with a GPS device. Basemaps range from those including only major highways and towns, to large and detailed databases that are very useful and comprehensive right out of the box. Reviews on this site will always include evaluation of the basemap and other pre-loaded data, and whether you will need to add to or update the basemap with additional free or purchased maps to make the GPS device truly useful. Basemaps may be updated and enhanced via purchased CDs, downloads from Web sites, or via purchased memory cards that have map and other data already in place.
