Can someone tell me how to filter out records with a speed lower than
for example 2km/h?
I am working on a Garmin Dakota 20 "Current.gpx" file, and the filter
options are = -x track,pack,speed,course,split=300s,title=%Y-%m-%dT%T
Everything working perfectly ;-)
..except that I want to remove all records with speed below 2 km/h
I can't think of a way to do that specifically, but if most of your motion is faster than that (2km/h is a pretty slow walk) you can get similar results with the 'simplify' filter http://www.gpsbabel.org/htmldoc-development/filter_simplify.html
That'll get rid of the noise at a stop light if you're a cyclist, for example.
