[OSM-talk] A project for winter - Building heights

[OJ W]

Now that the building-outlines have been done in London and elsewhere,
and with flight-simulator projects asking about 3D data, it might be
worth tagging the heights of some skyscrapers.

Every significant building has a wikipedia article, nearly all of
which include details of the height

what other tags can you think of for describing buildings?  Some
peoples' ideas are at:

To see progress in a city, Kosmos seems to be capable of drawing
things differently according to their height, e.g. there's an example
rule in:

p.s. will anyone make an isometric slippy-map next?
