This is my hobby project (not a weekend one). I know it sounds similar to other sites for GPS tracks sharing; I tried them many but didn't found options I needed for my mountaineering tracks (with lots of GPS errors because of bad satellite visibility). So I tried... :)<p>The result is this app: an online GPS track and route editor. It can join/split tracks/segments, waypoints, images, remove points, detect latitude/longitude/elevation errors (and automatically remove those errors), move tracks, ... And I hope all that is easy enough to use.<p>Do you think this would be useful to anybody?
