Mmh the underground is a real difficult problem but no, I do not want to
dig and measure the height of the mast.

I know buildings on steep areas which have two different ground levels
so simply building height is really difficult.

To state it:
1. define/tag ele=* for the object (ground)
2. measure the maxheight from this point -> height=*
3. do this for each object individually (eg. an object on top of another
one gets a different ele=* and its height.

For underground we would need a new tag.
