gpx_to_tsv.py

# A script taking all .gpx files from current folder and producing a tsv (tab-separated value) file with the id, coordinates, elevation, and time of all waypoint from these files.
# Warning: I have not tested it, but I suppose the presense of files with something else rather than simple waypoints will cause an error

#loop over these files

output.write('name\tlat\tlon\televation\ttime\n')
