Let’s say some place have some indoor foot paths. This could be foot paths inside a multi-level mall. Let’s say we want to map them into OSM.
The “base case” that always works is highway=footway + indoor=yes.
However, the Wiki also mentions this tag highway=corridor Tag:highway=corridor - OpenStreetMap Wiki .
It seems strange there are two distinct tags to map the same feature.
How does the community feel about highway=footway + indoor=yes vs highway=corridor?
