[OSM-talk-be] CORINE Land Cover 2000

[Lennard]

As some of you may know, last year the French have imported the CORINE 
Land Cover 2006 (CLC 2006) dataset. This dataset aims to classify every 
bit of surface of the participating countries. It is a project of the 
European Environment Agency (EEA) in conjunction with national mapping 
agencies. For Belgium, I believe this would be the NGI/IGN.

While they did get approval to import their CLC 2006 dataset, getting 
approval from the NGI/IGN in Belgium would probably be problematic, and 
actually getting the data from them even worse. Although, if we don't 
ask, we'll never know for sure. (Anyone up for contacting them?)

However, the CLC 2000 dataset is fully available on the EEA website, and 
has usage terms that seem to be very compatible with OSM.

"Unless otherwise indicated, re-use of content on the EEA website for 
commercial or non-commercial purposes is permitted free of charge, 
provided that the source is acknowledged."

On IRC, someone wanted to contact the EEA explicitly to obtain 
permission (for Belgium, but why not ask this for the entire dataset?). 
I don't see a problem with that, although for me the terms on the EEA 
site are clear.

I have made an overlay which shows the CLC 2000 data on the OSM map:

This is so you can already enjoy what we may be able to import, and 
maybe use it as a backdrop in Potlatch/JOSM or other editors to use. I 
don't recommend actually tracing the polygons, as a direct import is 
much easier.

The amount of changes between CLC 2000 and CLC 2006 is on the order of 
0.5% over the entire covered region. The overwhelming amount of polygons 
would be unchanged. I think there's not much harm in working with CLC 
2000, even if it is 10+ years old.

I have received the scripts used for the French CLC 2006 import, and can 
adapt and use those for an import of CLC 2000 for any area. I'm going to 
test them and prepare an import file for Belgium, which can be imported 
later on, if no valid objections are lodged.
