I have GPS data - point cloud in a shapefile. Now I want to average this data and get on output a single GPS track. Here I found images but can't find algorithm. Maybe gdal or postgis can do it? Any advise?

    You mention gdal and PostGIS - are you looking for solutions specifically for those softwares, a particular list, commercial or open source, or any? Related questions include: gis.stackexchange.com/questions/23464 and gis.stackexchange.com/questions/70623 (an answer links to the same paper you do, and there's further discussion on the method in comments and a link to a Stats SE question) and gis.stackexchange.com/questions/89010 (in particular has several ArcGIS tools mentioned). – Chris W Dec 7 '14 at 19:02
  • Thanks for comment. I found Expert gps but it sharewere. Found a gpstk library but not found examples how to work with it. Much interesting pca and principal curves methods. But can't find a algorithm description for geodata. If you know one it's will nice. – Kliver Max Dec 8 '14 at 6:00
  • @KliverMax have you found a solution for this; I guess I've posted a very similar question under the noise tag. Thus if you have an answer and post it; it could be useful. – dof1985 May 14 '15 at 7:20
