The program processes a text file that contains National Marine Electronics Association (NMEA) format GPS data and creates GPS track and waypoint text files which can be imported into the Delorme GPS mapping programs.

The NMEA file must have NMEA.TXT as the last characters of the file name. For example: 2005-JUNE-03_NMEA.TXT

The files created are:
  1. Track points showing positional data every two seconds.
  2. Waypoints showing speed every specified interval. Default is 15 degrees (distance).
  3. Waypoints showing the time at the same interval as the speed waypoints.
  4. Waypoints showing the number of satelites being used. Same interval as the speed.
  5. Waypoints showing a 3 if the solution is 3D or a 2 if the solution is 2D. Same interval as the speed.

The program was written to get a better idea of satelite coverage, help explain why sometimes the track would take off in a direction and come back again (wild points due to satelite coverage), see how fast we were traveling through an area and then finally, to mark the times along the track.

The last piece of information, the time, can be used to match up location with pictures. As long as the camera's date and time is syncronized to the GPS data, it is an easy matter to use the picture's creation date and time to locate where the picture was taken.

The program was created for and tested on a NMEA text file that was created using the following:
