[Talk-es] access to Spanish cadastre

[Tom Lee]

I've recently been researching Spain's cadastral database, which quickly
led to the work done on cat2osm and other projects by people on this list.
However, I find myself confused. I believe that links to bulk downloads of
the data exist on this page:

https://www.sedecatastro.gob.es/OVCFrames.aspx?TIPO=TIT&a=masiv

In fact, it is discussed in some detail on this OSM wiki page:

http://wiki.openstreetmap.org/wiki/Cat2Osm#Descargar_datos_de_Catastro

But when I attempt a download, it seems that I need an X.509 certificate. I
wonder if anyone can explain the nature of this requirement o a non-Spanish
citizen? I realize that some elements of the database related to land value
and ownership are sensitive, but I don't believe that these bulk downloads
include such data. The license terms associated with this data seem to be
quite open (
http://www.catastro.minhap.es/ayuda/legislacion/ovc/resoluciondgc20110323_tfs.pdf
), which makes this requirement all the more confounding.

Any insights are much appreciated.

Tom
