I am confused about the difference between these two tags: “height” and “building:height”. And which one of them should be used to specify the height of a closed way representing a building?
building:height is more or less used as 3D building key which can be used to define the height of a building without roof, if there is anyone. roof:height defines then the height of the roof. Both together make the height.
Building:min_height is equal to building:min_level, they describe in different ways the lower end of a building, e.g. of a bridge between two buildings.
roof:height is the lower end of a roof to the top. A flat roof has 0, a gabled roof with 1 floor level maybe 3 (in meter).
To make 3D mapping easier I use often only building:min_level, roof:levels etc.
You see, you get into advanced mapping area which is a little more complicate than just mapping 2D areas.
Thank you vvoovv.
Why is this a specific case? Can you please provide an example of some more common case? I sort of understood you that this case is somewhat specific. I would be grateful for that.
I didn’t understand you.
Why do we need to get the walls?
This building:part (19001901) is a dome. The height of the dome is 8 meters, 8 meters from the ground (so there are 16 meters from the ground to the top of this building:part). Is this diagram correct:
?
If this building:part would have walls, the height of those walls would still be: height - min_height
I still do not understand you.
What walls? Where are they located? The building part 19001901 has no walls.
I apologize for insisting on this walls issue.
Thank you vvoovv. I don’t understand it. I won’t insist on this anymore.
I still do not understand how did we end up with walls. They are not mentioned among the keys of the 19001901 building part. I haven’t asked about the walls either.
Maybe the walls are somehow connected with ‘roof’ keys, and I am not aware of that.
