Overview

How to use

Getting the length of a GPX file

import fastgpx

gpx = fastgpx.parse("example.gpx")
print(f'{gpx.length_2d()} m')

Iterating the tracks of a GPX file

import fastgpx

gpx = fastgpx.parse("example.gpx")
for track in gpx.tracks:
    print(f'Track: {track.name}')
    print(f'Distance: {track.length_2d()} m')
    if not track.time_bounds.is_empty():
      print(f'Time: {track.time_bounds().start_time} - {track.time_bounds().end_time}')
    for segment in track.segments:
        print(f'Segment: {segment.name}')
        for point in segment.points:
            print(f'Point: {point.latitude}, {point.longitude}')

Encoding and decoding polylines

import fastgpx

locations = [
    fastgpx.LatLong(64, 10),
    fastgpx.LatLong(66, 11),
]
encoded = fastgpx.polyline.encode(locations, precision=6)

decoded = fastgpx.polyline.decode(encoded, precision=6)
