I have a GPX track containing latitude, longitude and elevation data. The recordings are done by a Garmin device and have been recorded in varying intervals (between 1 and 44 seconds). I would like to know my (interpolated) location data for every 10 seconds.
I have installed gpsbabel and ran this per page 138 in the manual (on Mac OSX)
gpsbabel -t -i gpx -f in.gpx -x track,pack,split=10s,title="LOG # %c" -o gpx -F out.gpx
The file out.gpx is created, but appears to be exactly the same as the input file. Am I using the wrong function?
When the input timestamps are
2016-11-27T22:56:58.000Z 2016-11-27T22:57:02.000Z 2016-11-27T22:57:07.000Z 2016-11-27T22:57:13.000Z 2016-11-27T22:57:19.000Z
I would like to have a 10 second interval output like
2016-11-27T22:56:58.000Z 2016-11-27T22:57:08.000Z 2016-11-27T22:57:18.000Z
with the corresponding (calculated) coordinates for those sections.
A sample of my original data can be found here.
