Definitely interesting stats. I would interprate -2 for example as a hole (which also functions as a building) that is 2 levels deep. But levels probably isn't the tag to store that info. 0 makes sense for buildings that are underground.
A .5 makes seems logical to me. Some offices will have a mezzanine and depending on the height and layout could be considered a half floor. Some buildings also have stories in between stories. So a full two story house in the front, with a story at the back which is vertically between the two. But I don't think the other decimals make much sense, to me it would seem like a mistake. -Heikki On Tue, 27 Oct 2020, 13:37 Colm Moore, <colmmoor...@hotmail.com> wrote: > Hi, > > There's a discussion at > https://twitter.com/CiaranStaunton/status/1320505496105820163 on > building:levels=* https://wiki.openstreetmap.org/wiki/Key:building:levels > which is used for marking the number of above-ground levels of a building. > > There are about 3,000 entries on Ireland where the number isn't a whole > number.
