![]() ![]() They are stored as ElementTree DOM objects. Another possibility is to use extensions to save the speed in GPX 1.1. If you want to force using 1.0, you can gpx.to_xml(version="1.0"). But if you have a GPX 1.1 object, changes in the speed attribute will be lost after gpx.to_xml(). If you parse GPX 1.0 and serialize back with gpx.to_xml() everything will work fine. That's because the library object model works with both GPX 1.0 and 1.1.įor example, GPX 1.0 specified a speed attribute for every track point, but that was removed in GPX 1.1. Be aware of this!īe aware that the gpxpy object model is not 100% equivalent with the underlying GPX XML file schema. Most applications will ignore such errors, but. For example, if you set gpx.email to "my.email AT " the generated GPX tag won't confirm to the regex pattern. ![]() The generated file will always be a valid XML document, but it may not be (strictly speaking) a valid GPX document. Gpx.py can parse and generate GPX 1.0 and 1.1 files. GPXTrackPoint ( 2.1236, 5.1236, elevation = 1236 )) # You can add routes and waypoints, too. append ( gpx_segment ) # Create points: gpx_segment. append ( gpx_track ) # Create first segment in our GPX track: gpx_segment = gpxpy. GPX () # Create first track in our GPX: gpx_track = gpxpy. to_xml ()) # Creating a new file: # - gpx = gpxpy. elevation )) # There are many more utility methods and functions: # You can manipulate/add/remove tracks, segments, points, waypoints and routes and # get the GPX XML file from the resulting object: print ( 'GPX:', gpx. Usage import gpxpy import gpxpy.gpx # Parsing an existing file: # - gpx_file = open ( 'test_files/cerknicko-jezero.gpx', 'r' ) gpx = gpxpy. See also srtm.py if your track lacks elevation data. There is also a Golang port of gpxpy: gpxgo. You can see it in action on my online GPS track editor and organizer. GPX is an XML based format for GPS tracks. This is a simple Python library for parsing and manipulating GPX files.
