RoadMap is an open source (GPL) program that provides a car navigation for
Linux, UNIX and Windows CE (a.k.a. PocketPC). It displays a map of the
streets, tracks the position provided by a NMEA-compliant GPS receiver,
identifies the street matching this GPS position and announces the name of
the crossing street at the next intersection. A trip feature allows
RoadMap to display routes, tracks, and provide some basic navigation
information (distance to the next waypoint, direction, speed, etc..).
Voice messages are generated that duplicate some of the screen
information.
