Ok, you want to have one way for the whole building. I dont think this would work. What differs a full 5 level multi-story parking and a 4 level parking on top of one shop level? Why use rooftop instead of multi-story? Where is the border when to use rooftop and when multi-story? Majority of levels used not for parking? Suppose a way with the tags: building=yes building:levels=5 amenity=parking parking=rooftop shop=department_store How much of the building is the department_store, how much parking? What about a amenity=school? we cannot reuse the amenity tag on the same way. I would suggest two overlapping ways: building=yes amenity=parking parking=multi-story building:levels=5 building:min_levels=2 layer=1 and building=retail building:levels=2 shop=department_store If we have only the roof used, we could map it as surface with a min_height and layer. > I assume there is a need to create a new parking=rooftop or similar > tag, which can then be used to create more accurate renderers > (perhaps by also placing the parking=rooftop tag onto the > service=parking isle service roads, so they are similarly > (translucently?) rendered. translucent should be IMO only indoor (aka tunnel) ways. -- greetings Holger _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
