R script to make an average GPS / georeferenced track by combining/merging two or more into a “line of best fit”
R script to make an "average" track of several GPS tracks by combining/merging them into a "line of best fit". Made by Michiel Faber http://www.openstreetmap.org/user/Michiel%20Faber and wrapped and "packaged" by Guttorm Flatabø. This isn’t the perfect way to do it, but it works.
The "test-tracks" directory contains six tracks for the same route that you can test the software with. "averageTrack_reference.gpx" is an average track made with this script.
TopoFusion software uses a more sophisticated method and have written a paper about it http://www.topofusion.com/network.php. The issue has also been discussed on the gpsbabel-misc mailing list http://goo.gl/HJE5s.
