Hey,

I am trying to filter out the following way types out of an osm.bz2-file (malta-latest.osm.bz2 from Geofrabrik): footway,path, cycleway. Until now I did this by the following command:

C:..\bin>osmosis --read-xml file="malta-latest.osm.bz2" --tag-filter accept-ways highway=footway,cycleway,path --used-node --tag-filter reject-relations --write-xml file="malta-filtered.osm.bz2"

This works as it filters the right ways, but it also includes some nodes (mostly highway=bus_stop and public_transport=*, but also some others) that shouldn't be in there (imho), because there is no (visible) connection to any of the correct ways. I don't really understand, why this is done..!?! :-( Has anyone an idea and could help me?

Thanks in advance

Chris

The issue is a simple ordering problem. By specifying --used-node before you drop the relations with --tag-filter reject-relations, you get all nodes either used by one of the ways you have selected, or used by any of the relations in the file. Swap these two arguments around, and all works as expected.

Maybe you can have a closer look at osmfilter as an alternative tool.

Read its documentation in the OSM wiki.
