Read GPX file
Read all track points and waypoints and put them into arrays
INPUT:
  • GPX file name (and path)
PROCESS:
  • Convert XML to DOM data
  • Track points: Extract latitude, longitude, elevation and time
  • Way points: Extract latitude, longitude, elevation, time and name
OUTPUT:
  • Track points: double array [latitude, longitude, elevation] and cell vector {time}
  • Way points: double array [latitude, longitude, elevation] and cell array {time, name}
If an elevation is not present, this elevation is set to zero.
If a time or name is not present, this time or name is set to empty.
If any lat, lon, elev. is not a number, 'CORRUPT GPX FILE!' is returned for the first way point name.
Write GPX file
Function to write a GPX file with given track and way points.
INPUT: DataGPX, a struct with the fields:
  • fileName: string, default 'MyGPX' + date
  • header: string with header information, default: 'version="1.1" xmlns="http://www.topografix.com/GPX/1/1"'
  • wpts: lat, lon, ele, double nwpt x 3 or nwpt x 2, nwpt is number of way points, default: no way points
  • default for elevation: 0
  • wptTime: time of a way point, cell array nwpt x 1, default: no way point time
  • wptName: name of a way point, cell array nwpt x 1, default: no way point name
  • trkName: name of total track, string, default: file name
  • trkPts: lat, lon, (ele), double ntrk x 3 or ntrk x 2, ntrk is number of track points, default: no track points
  • default for elevation: 0
  • trkTime: time of a trk point, cell array ntrk x 1, default: no track time
All fields are optional
A demo file is included
