Ah, I see that slightly to the north west is a school where the school
grounds are one big polygon and the individual buildings are building
footprints. So that's a good example.
I look at the tags for the building footprint in the "Basic" tab, and
I get the option of "Building" and "Public Building" but I don't
see the tag "Office Building"
So the tags for the smaller polygon are;
building = yes
amenity = public_building
Which I suppose is correct, since the offices are government offices?
Or is amenity = public_building reserved for stuff like museums, art
galleries and libraries?
Cheers,
Nick
