As I understand it option a) is correct. If put on a building it would
mean that the ground level is at this height. In some specific cases
this might bring problems though: imagine a lot of stones and earth is
transported on the hilltop, the elevation clearly changes. If you

Should one not then, to avoid misunderstandings, use ele only on
ground-level features? We can define away on the wiki all we want;
Generelly yes, but if there is a tower on the summit, there is not
really any other way.

You would normally put a natural=peak tag next to the tower anyway. Or
if you don't, then attach ele to the bench near the base of the tower
or so ;)

I might add that, if you put a tower on top of the building, I'd expect the
ele tag on the tower to be the sum of the building's ele and height

I think this may be a language issue. In American English at least, one
would not use/read the word elevation to mean the height of an

well, you could say that height is the maximum vertical extension
Simple solution: use ele:top=* for the elevation of the top.

From what has been written here it seems that elevation clearly does
not contain buildings.

OK, following this discussion it seems clear that either nobody
interprets the wiki literally (the elevation at a given point), or
that the English term elevation never refers to man_made structures.
In each of these cases the tagged value for ele would be the elevation
of the surrounding ground.

If a structure is located on sloping ground, do you record the elevation of the

the highest and lowest points, or what?
