Turn your NMEA0183 GPS log into a MPEG movie
This program parses NMEA0183 data from a GPS data logger, and replays the sailboarder, kite surfer, cyclist, motorcyclist etc being logged on a 3D moving map. The end result is either a Y4M video file, that is ready to be converted to a movie file (MPEG, AVI etc). Optionally, the user can take screenshots. This program can display/record multiple participants (ie: display/record more than one GPS file).
