I am interested in obtaining the foot paths from OSM data. Specifically I consider the area within the city limits of Berlin. I downloaded the corresponding OSM file from Geofabrik and I intend to use osmosis to filter the data. As a first step I would like the ways which are usable by pedestrians. I have started out with this:
osmosis --read-xml file=berlin-latest.osm.bz2 --tag-filter accept-ways highway=footway --used-node --write-xml file="berlin-foot.osm"However, I am not sure about when the tags footway and pedestrian. Essentially I want to end up with a graph so I can perform routing tasks. Will I need both relations in this case? Also, at least the pedestrian highways seem to sometimes contain "area=yes" tags. Can I filter on the way type as well?
Edit: I would like all the ways which can be used by pedestrians, I don't want to restrict myself to pedestrian-only ways. My current version is this:
INPUT="berlin-latest"osmosis --read-xml file="${INPUT}.osm.bz2" \ --tag-filter accept-ways highway=footway,pedestrian,path,track \ --tag-filter reject-relations --used-node --write-xml file="${INPUT}-foot.osm.bz2"osmosis --read-xml file="${INPUT}.osm.bz2" \ --tag-filter accept-ways highway=* \ --tag-filter accept-ways sidewalk=both,left,right,yes \ --tag-filter reject-relations --used-node --write-xml file="${INPUT}-sidewalk.osm.bz2"osmosis --read-xml file="${INPUT}.osm.bz2" \ --tag-filter accept-ways highway=residential,unclassified,living_street \ --tag-filter reject-relations --used-node --write-xml file="${INPUT}-residential.osm.bz2"osmosis --read-xml file="${INPUT}-sidewalk.osm.bz2" \ --read-xml file="${INPUT}-foot.osm.bz2" \ --read-xml file="${INPUT}-residential.osm.bz2" \ --merge --merge --write-xml file="${INPUT}-pedestrian.osm.bz2"This seems reasonable, although I am still uncertain regarding area tags. Also I might remove the access=private ways. Another problem is that some highways are missing their sidewalk tags, so some more mapping would have to be done...
