Taking this example of a fairly standard house: Should that be mapped as roof:levels=1 as presumably there is loft / attic, or would you only map it as roof:levels=1 if there was a visible window / loft conversion in the roof? asked 04 Apr '23, 22:27  Al3x25 edited 04 Apr '23, 22:29 |
One Answer:
Hi, Please see here for guidance on building levels:- https://wiki.openstreetmap.org/wiki/Key:building:levels It indicates your example would be roof:levels=1 and building:levels=2 Regards Bernard, answered 06 Apr '23, 06:48  BCNorwich |
Thanks. I was originally looking at https://wiki.openstreetmap.org/wiki/Key:roof:levels which is less clear on the matter. It only has examples for roof:levels=2, where both roof levels in the example images have windows.
Hi, Yes a roof level is a roof level whether it has windows or not, and there can be several levels within a roof. The two pictures in your link above show, (from the arrangement of the windows), that there are two levels within the roof, hence roof:levels=2 in those instances. Without windows as a guide, you can only assume that there is one roof level.
