Is there a (current) best practice to simplify ways? I have found:


But besides not being alive, here (http://permalink.gmane.org/gmane.comp.gis.openstreetmap.devel/26854) it says:

Ok, I found out that osmosis-simplifyways is not compatible with osmosis 0.43.1. It will work with 0.39. But the tool is buggy. It removes nodes from ways where it connects to other ways.

Since I want to use the data for routing I guess it wouldn't work anyway.

Is there some well tested Ramer–Douglas–Peucker implementation to simplify osm data properly?


You can find some hints in the open source code of the JOSM editor, that program has a way-simplify-feature inside.

Or have a look at that JOSM plugin named RemoveRedundantPoints


It requires ArcGIS, but see my detailed response here in another GIS StackExchange thread regarding building networks and simplifying data while maintaining the topological structure:

Building Large Network Datasets from OpenStreetMap in ArcGIS?

  • Guess I will write something myself. Still, thanks, guys. – user54586 Aug 21 '15 at 15:13
