Gpsbabel track segments
Continue reading How I converted Google MyTrack kmz/kml to Strava gpx (using Linux and GPSBabel). (Data are recorded by human, so there are segments probably because human paused recording.) I have used following command from this answer: gpsbabel -t -i gpx -f input.gpx -x track,speed -o unicsv -F output. This is basically a bunch of raw bash commands and I didn’t do anything to eyecandify them, sorry for that I basically copypaste all my steps here, minus the reading and trial-and-error bit of course. All track points seem to be correctly ordered (from quick scrolling trough it). I am using the input format magellanx (which works successfully for me with waypoint files) and various output formats such as mapsend and gpx.

gpx.Īs this needed a bit of tweaking I captured (ugly as it is) what I did so I (or you, reading this) can reproduce it later. I am trying to convert a track file from a Magellan Explorist 400 (firmware 4.2.02) using GPSBabel 1.3.0 on Mac OS 10.4.7.
This implies that specifying a filter before reading any data ('-xIt should be noted that data filters are invoked in the internal pipeline at the point that corresponds to their position on the command.
The solution is to somehow add timestamps to each trackpoint during conversion to. Data filters are invoked from the command line via the '-x' option. The problem is MyTracks does not save per trackpoint timestamp info, just the trackpoints themselves, so Strava apparently can’t calculate its own segments etc., and as a result, will drop you an error when you try to upload a. I to find the furthest point from line segment AJ and scan points K through. My dad asked me to convert a bunch (somewhere between 10 and 100) of old rides he saved in Google MyTracks back in ~2011, to something that Strava can understand. I thought of using gpsbabel for such track simplification / optimization job.
