Hi everyone:

My name is Ander Pijoan and I'm a student at the University of Deusto. We
are working on an application to convert data from a goverment database
called Catastro (which has been openned to all users little time ago) to
osm format in order to do massive imports. This database contains all the
urban and rustical info about landuse, buildings... and lots of interesting
things to add like sub_stations, amenities or even streetlamps and trees.

Here is the wiki where you can follow the project:

For big cities maybe there is stuff that is not necessary to import but for
small villages its a great improvement. The conversion part is almost ready
but we have one bit missing, the building tagging for 3d renderers to
render propperly. We've seen you will have an OSM Dev weekend but we don't
know if we will be able to attend.

Example of current data stored in OSM: http://i.imgur.com/vComo.png
Data we can import from Catastro: http://i.imgur.com/kqCex.jpg

The tags on the wiki related to 3D rendering are quite reduced for all the
information Catastro database gives. We have information about part of a
building are balconies, terraces, porchs... http://i.imgur.com/i6LJ5.png

So our question is if there are some more tags already "standarized" or
recommended for this data, it is expected to have some or we should make
some operations to calculate the shape it should draw on 3d and type it
like min-height and height.

Thanks a lot, Cheers.
