You will just get a Not Found. You can get the node history but that won't really help much. Sometimes people make the old node be one of the tag-less nodes of the new building way, but that's not required, maybe not even very common. And maybe in your case it would make things harder rather than easier. -- Nicolás _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
