[Imports] Spanish cadastre

[Cruz Enrique Borges Hernández]

> The problem with TIGER I believe is that the converter added lots of
non-geographical data, some unverifiable and mostly easy to obtain from
TIGER itself provided that the tlid is maintained.

I did not know the TIGER case but in this case we have the politics of only
use ALREADY existing metadata. Even in that case, we only use where we can
make sure the traduction is correct ussing more general tags when in doubt.
We haveeven  switch in the cat2osm tool that create different files
acording to their "correctness".

With that in mind, the cadestre data is update every four month and could
be update that way becasue we have already consider that in the tool.
Satellite images are update much less frequently and local view from time
to time can help to maintain this data. But in the end, the desission on
import or not to import the data have to be taken by the local importer. In
the results page there are files that the LOCAL MAPPING COMUNITY have been
corrected and said it case with the reality of the place. They are waiting
for approval to proceed to upload the data. The best example probably is

but there are others in

in the current editors.

Deffine "very complicated". I think that the data ALREADY in the database
is VERY VERY DIFFICULT to edit NOW.
I have spend more that one hour to FIX a single relation with JOSM!!!!! We
need to fix the editor, not the data!!!!

Can you point us to these shell scripts? We have though that it is forbiden
to use them in any case. We are currently talking follow this aproach:
editing and conflating in JOSM and after the aproval of local comunity the
data will be uploaded by the person in charge of that area using some
script that split and upload the data in small chunks.
