Or man_made=canopy? http://en.wikipedia.org/wiki/Canopy_(building) I think I'm going with man_made=canopy. But that doesn't work for "a building with a contiguous floor over a parking area", unless you "split the building", in order to use multiple layer tags. The building exists at both layer=0 and layer=1. Honestly, I don't like covered=yes here. It's a hack, but unless and until there is support for true three dimensional mapping, any solution is going to be a hack. Splitting the building into two parts, one at layer=0, touching the parking area, and one at layer=1, encompassing both the area next to and under the parking area, is another solution. It's similar to what we'd do with a highway when we want it to exist at multiple layers. But it's probably unprecedented for buildings. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
