OK, there are ways to edit GPS tracks. There are many offline track editors that let you do that.
But now there is one more online track editor -- the new version Trackprofiler.
The full list of options is now:
- Upload and merge tracks
- Smooth track profile graph
- Upload, automatic position and edit images
- Split parts of track, join track segments, delete parts of track
- Add waypoints
- Change waypoints description and icons
- Show descriptions on map/graph
- Show your location on graph/map
In italic are new and enhanced features from the last upgrade.
