Doesn't seem to be a reliable way to filter high velocity points.
Take successive derivatives of all points and filter on that?
- Comment out the bogus points in the gpx
- Use gpxplot.py to check for velocity peaks quickly
Splits tracks at long breaks (e.g. lunch).
Split after 30mins:
$ gpsbabel -i gpx -f in.gpx -x track,pack,split=30m -o gpx -F out.gpx
- short descriptive name
- original GPS name
- "Day x: Description"
- Garmin waypoint symbols
Garmin GPS III+
- Drinking Water
- Water stops, springs, etc
- Swimming Area
- Picnic Area
- Lunch stops
- Railway crossings
- Google Maps
- Paste the gpx URL in the google maps search box
