[OSM-talk-ie] Corine Import - update

[Paul Byrne]

Hi
Looks good nice work.
Allot of land I would have tagged landuse = farmland or farm is being tagged
as landuse =  medow. Some of the medow areas are fairly big and complicated
shapes, I'm not sure how easy it would be to split up and retag as farmland.



 Worked bogs, being excavated for their turf (bog=worked). Do we need

I have been tagging this:

natural=wetland
wetland=bog
bog = cut
