Never mind. I can't speak a word of french :-D

The question is... which border, exactly?

My guess is that the national borders from the french Institut Géographique 
National and the spanish Instituto Geográfico Nacional are different. Maybe 
not a lot different (not 10 km), but I wouldn't be surprised if they are 100 
meters off someplace.

My point of view is that we'll have to fix the administrative boundaries 
anyway (and maybe merge with the spanish SIOSE land use survey in the 
future).

Keep in mind that the current borders in OSM are from the CIA factbook, and 
quite inaccurate. At some point, we'll have to discuss importing the national 
borders from both IGNs, and who is invading who :-)

Until then, I don't think that cutting off the CORINE data will do any good. 
If we're gonna cut off the data, we might as well do it with the right 
boundaries.

Furthermore, I don't think that any data you import into Spain is going to be 
destructive.


So, if you ask me... import everything. We'll have time to fix things up.


Cheers,
