LOL. So much for the single European market!

I suppose not. Also, currently this is very WIP. According to official
documents only Spanish citizens will be able to download or
redistribute the original shapefiles, one by one, for each of the >
3000 municipalities. Once converted, altered or translated in order to
create a derivative work, it may be used freely with a wold-wide
license almost without restrictions. I think they feared their website
collapsed or something.

Yes,  it includes street names among many other things. I do not know
how are the files they are releasing, but Catastro is the most
accurate source in the country (I suppose centimeter-accurate, as all
architectural works are projected using it as a base, and it showed
even the inner structure of the buildings). It will not mean the end
of mapping in Spain, as some info (road information, natural
resources, locality names, business info) is handled by different
national or local agencies.

I must admit I thought we were already allowed to use it. I've added a few
street-names in Spain on the basis of the Catastro mapping.

They are not or were explicitly banning it, but I think what they want
to say now is something along: "Come on, OSMers, stop hiting our WMS!
OK, I will give you vectorial data for free instead, if you promise to
behave". :-)


Is the vector data available in Potlatch? Does it show street-names?

I am pretty sure that Catastro is doing good job also with the updates. Perhaps
we should start seriously to think about alternative ways for utilising foreign
data together with OSM data and not just import and merge everything that is
available. It can be pretty hard to update the imported, merged and perhaps user
enhanced data with the updates coming from the original data provider. But if
the data will not be updated OSM will have a partly enhanced but also partly
outdated snapshot of data. The aim should be up-to-date and user enhanced data.

Great news for you. In France, we have access to the WMS but not to the
original vectors (although we found a way to reconstruct the vectors). But
finally it was not so bad because it moderated the automated imports
(another thread on this list). We use it as a primary source for some
objects (like buildings and addresses) but we also learned that this source
like others has variable quality and freshness. Cadastre is a great source
if you use it cautiously.

If anyone can get their WMS server working in Potlatch, that would be 
useful.

[OSM-talk] Spanish official land register (Catastro) changes its license

[jynus]

"Catastro" is the official land register for Spain. I holds
information about every single plot and building, street, street
numbers, and lots of statistical information about them. However, it
has traditionally been quite restrictive or unclear about its usage
policy, and that is why it was not used as a source for the project.

Well, the good news is that yesterday it made and official statement
in which it changes the license to some of its services: [1]

In short, it allows (as far as I understand):
* Massive downloads from its web page (unless done badly, as a DOS, etc.)
* Downloading of shapefiles (vectorial data) and alphanumeric info of
every single Spanish municipality
* They do not allow redistribution of exact copies of their data, but
if the data is transformed or adapted in any way, *the resulting work
is fully copyright of the author of the transformation*
* They explicitly allow commercial usage of the derivative works, but
request authorship
* The only data they are not freeing now is WMS usage and private data
like property owner names

I think it is an announcement with the same impact as the one from the
French Cadastre or Ordinance Survey permissions, maybe even better, as
we have directly permission to get and use the vectorial data, updated
every 3 months.

We are yet greatly shocked on the Spanish mailing list, but if anyone
is interested we will start working on coordinating there and on the
wiki. We have yet to review the exact conditions and how to conform
with them, and also see how are we going to merge it with existing
data.

Also thanks to anybody involved in making official data like these
more open; it seems like a license done exactly so it can be used in
projects like OSM, and I think that is not a coincidence.
