If all you want to know is "are the routes different", then you could use something like the Fréchet distance:

This would give you a numeric value for how different the path is. daniel On Tue, Jul 14, 2020 at 8:09 AM Martin Schmidl <msts.mar...@gmail.com> wrote: > Hi, > > In a project of mine I am using OSM data from a city for 7 different > years.
