Imports are not universally welcome in OSM. Please discuss, ideally on 
the imports list, exactly what you plan to import and how.

Such information is almost certainly not suitable for OSM. Remember that 
OSM is a user-editable database, so you should not import anything that 
cannot be meaningfully edited by users.

Even if there were - OSM cannot be a repository of detailed 3D shapes 
for all the buildings in this world, this is simply outside our scope 
and outside of what our editors and our database can handle.

Imports may make the map look nice in the short term, but they have the 
potential to make editing harder. Also, if you import data where there 
is no local community, you risk creating huge data dumps for which 
nobody really cares, and which nobody maintains.

The value of OSM is not in the huge amount of data that has been 
collected, but in the community that keeps this data current.

Under no circumstances should you import data for all of Spain while 
sitting at your desk - if at all, then you can help local users to 
import cadastre data where there's interest and where there *are* local 
users to begin with.
