ugh and i'm pretty sure I have to complete that quest for a structure before I can answer additional questions about it! #osm
@deutrino The general advice I remember reading is "if you aren't sure, just put down what you do know." What I usually do is, if I can count the floors, I put that and just assume there's no basements, otherwise I leave it blank.
I guess you could also go look up real estate listings.
@faoluin there isn't any real consistent guidance on this, here's an example: https://old.reddit.com/r/openstreetmap/comments/m7ynb8/do_basements_with_windows_count_toward/
there are like 3 different answers in just one small thread.
I think I'm gonna end up doing this:
* if the basement only has teeny windows near the top of its walls and is mostly underground: not a level.
* if the basement has more normal windows and/or an entrance door and/or at least one wall most/all above grade.... it's a level??
@deutrino Yeah, it's kind of a best effort thing. I guess the idea is if someone lives there or knows the place, they can go fix it. Idk. :P
@faoluin from the wiki "For the purposes of this tag, 'ground level' is defined to be the lowest entrance to a building."
so (contradicting one of the reddit commenters) it looks like if the basement has an access door, it's the ground level even if it's surrounded with earth on 3.5 sides.
@deutrino One thing I found about the wiki is it has a heavy bias for European building layouts and language, which can be very confusing for mappers in the US. :/
@faoluin yeah, I was wondering if detached houses with basements in Europe do the 'teeny windows at the top of a wall sticking 2 feet out of the dirt' thing like many American homes have
