GpsDrive is a car (bike, ship, plane) navigation system. GpsDrive displays your position provided from your NMEA capable GPS receiver on a zoomable map, the map file is autoselected depending of the position and prefered scale. Speech output is supported if the “festival” software is running. The maps are autoselected for best resolution depending of your position and can be downloaded from Internet. All Garmin GPS reveiver with a serial output should be usable, also other GPS receiver which supports NMEA protocol. GpsDrive is written in C with use of the GTK+ graphic toolkit and runs with Linux and FreeBSD. It allows you to import and georeference topographical maps, to upload tracks and waypoints from different GPS recievers like Garmin or Maghellan, and to navigate with all standard GPS-tools (Bearing, heading, speed, altitude,…).
