GpsDrive is a car (bike, ship, plane, foot) navigation system. GpsDrive displays your position provided from a GPS on a zoomable map, the map file is autoselected depending on your position and preferred map scale. All GPS receivers which support the NMEA protocol should be usable, as well as many USB GPSs using a binary protocol known to the Gpsd daemon.
Included on the Live GIS Disc are street maps for the city of Barcelona which can be explored and navigated in map scales from 1:1,000 through 1:200,000.
