GPX Track Editor

Make your own trail maps, using your tablet or smartphone.
Record tracks, or import tracks from GPX files.
Clean up your track data, manually and/or automatically.
Use your trail map for navigation, with or without an Internet connection.
Your tracks and waypoints are displayed over the (optional) background of a Google Map, either the default road map or a satellite image.

Editing features:

* Split and join tracks.
* Connect tracks to form 3-way and 4-way junctions, with the same coordinates in each track that meets at the junction point, to establish the topology of a network of tracks.
* Eliminate superfluous trackpoints, with the option of preserving junction points against elimination.
* Take the average of 2-5 tracks, to even out the errors, or, for example, to establish a street's center line from tracks for the sidewalks on either side of the street.
* View the results of averaging or reducing tracks, before accepting the results.

Documentation is available via the thorough help system within the app.
