-Works with vectorial maps and calibrates raster maps
-Organizes paths by creating waypoints, routes and tracks
-Uploads/downloads data to/from your GPS
-Uses altitude DEM data
-Supports GPS real-time navigation
-Sends/receives vehicles position and display tracks on maps in real time
-Provides autorouting and geocoding functions
-Supports integration with Google Maps and Earth (in 3D also)

Potential use:
-Search and rescue
