I have a large number of GPS tracks from a number of different users. I'd like to identify tracks that take the same route and remove those duplicates. For example, a user takes the same streets from the same origin/destination, but obviously with GPS accuracy issues, the lat/longs aren't exactly the same.
Any sort of intersect function simply provides a large set of intersecting sections, but doesn't compare a full track from start to finish.
Currently using PostGIS, but trialing in ArcGIS to visualize and test a procedure before applying it to the 1,000+ tracks and 8 million datapoints.
