Hi Ciprian, to use Osmium is certainly a good idea if you planning similar complex filtering tasks for the future!
If you want to try it with osmfilter, there are two ways: 1. Manipulate XML Filter positive: osmfilter input_data.osm --keep="landuse=" -o=filter_data.osm Then manipulate the XML file by inserting a line "<delete>" right before the first node. Then apply this manipulated file to the original file: osmconvert input_data.osm filter_data.osm -o=output_data.osm (osmconvert will internally treat filter_data.osm as a changefile ".osc".) 2. Use Dependencies I never tried it to this extend, but it should work. We assume that nodes may stay in the file IF (and only if) they are a member of a way (or relation) OR they have at least one own tag: osmfilter input_data.osm --keep-nodes="*" --keep-ways-relations="landuse!=*" -o=output_data.osm Markus -------- Original-Nachricht -------- > Datum: Wed, 8 Feb 2012 22:53:58 +0200 > Von: Ciprian Talaba <cipriantal...@gmail.com> > An: mar...@gmx.eu > CC: dev@openstreetmap.org > Betreff: Re: [OSM-dev] Filtering out elements from a planet extract > Hi Markus, > > I am OK with removing all the nodes that are part of a landuse way no > matter if they have their own tags or not.
