Pitfall in this example: If there is more than one track in the source, simpify seems to work on each track individually, so there might be more than 2000 waypoints in the output.
#Gpsbabel split track segments software
The reason one cannot use the name 'current.gpx' is that the software treats 'current.gpx' as an output only file, so it will not read it regardless of a timestamp. I can make a track either on Google Maps. So by getting the first 500 waypoints, get the range up to including 8min 19sec. For that I use GPS Visualizer’s draw function. The example takes an unknown track, reduces it to 2000 points, adds a timestamp beginning at the and then makes four tracks with 500 waypoints each. If you dont need the time information, you can add a fake time, and then splitt according to the added time. When using the following command, the output GpsBabel generates still only has a single track and a single segment: gpsbabel.exe -t -i gpx -f input.gpx -x track,pack,sdistance80k -o gpx -F output.gpx I also tried this, same result: gpsbabel.exe -t -i gpx -f input.gpx -x track,pack. This should work for example with the GPX tracks generated by Hello I'm running GpsBabel 1.5.1, and would like to split a long, single-segment GPX file into 80km segments. # by transforming UNICSV waypoints back to trackpoints # convert separated UNICSV files back to GPX track files
I added a separation of waypoints and tracks and a little bit of "compression" to Harald's script (which works in zsh as well). Thanks for the script! It's useful to me as well because my Garmin bike navigator starts to throw trackpoints away after a certain number of trackpoints is reached.
