I'm not particularly a fan of importing this kind of data unless it is carefully inspected. I'm becoming more and more convinced that land cover information should belong in a separate database, since it doesn't have any topological relationship to any other data. > I have some examples over the south-west of Sofia > http://img43.imageshack.us/img43/431/imagerym.jpg > and a test changeset over the eastern Rhodopes > http://www.openstreetmap.org/?lat=41.6761&lon=25.9656&zoom=12&layers=M The main OSM database is not a place for this kind of test import, especially considering you named the forests as "test data". The Bing imagery isn't of sufficient resolution to tell how good this data is, but I see that many (all?) of the ways are duplicated four times, only one of which belongs to the multipolygon. I would highly recommend that you revert this changeset until further discussions occur on this list and with any relevant local mailing lists or groups. -Josh _______________________________________________ Imports mailing list Imports@openstreetmap.org http://lists.openstreetmap.org/listinfo/imports
