Hi,

    before this is imported it would at least need proper
documentation on the Wiki import catalogue.

In addition to the points mentioned by Michael -

> * adjacent buildings do not share nodes * no multipolygons at
> buildings with holes - those would have to be created manually *
> The buildings are not orthogonalized (q in JOSM) * nodes at very
> obtuse angles (e.g. 88°) should be removed.

I would like to add

* source tag on every building (source tag on changeset would be enough)
* existing buildings are not reflected - they would have to be removed
from the import data.
* very small buildings seem to be badly traced (triangular shapes etc)
- - perhaps just drop everything below 10 square metres or so.

There seem to be a number of mismatches between the data and Bing
imagery - but I guess that's because basemap.at is newer? Examples:

Frederik
