[Imports] Hungarian CLC import

[Jaak Laineste]

Hello,

  Couple of points:

 1. I would not suggest to import landuse:farm polygons at all. We did it in Estonia and now try to get rid of them, as they are not accurate (due to Corine definitions) and they make editing in countryside, especially with Potlach much harder. Now you have a lot of multipolygon relations which are not for average mapper etc. We have had a lot of complaints after import about it. Just pick as little data as possible : forests, wetlands perhaps. Mapping should be fun, and remain so, but with all Corine multipolygons you will make it quite a pain.

 2. Test import import in one region and try to do manual mapping in the same area for a few months. See if community can handle it. You do not need to hurry. Removing already imported stuff is much more harder, you'll already have some additional edits done then etc.

 3. Full attribution would fit better to changeses, not to each object. You have quite long one, again a lot of "garbage" is generated. Short reference source:CLC would be enough for objects, so later you can easily.

ps. I am importer of Estonian CLC data and I do regret it. I would not suggest to massimport it (and most other datasets) at all. Today I would just publish it for manual copypasting and reference (like aerials). But I cannot stop you, this is probably one of those mistakes what everyone needs to do themselves. I do know the temptation to have nice colored map with Corine, but OSM is not about as detailed map as you can do. It is about fun of mapping.
