That is not quite accurate in my experience. As i explained in https://lists.openstreetmap.org/pipermail/talk/2017-February/077553.html landcover mappings like corine are based on selecting the least unlikely of a fixed set of landcover classes at a certain scale based on certain criteria and reference areas and this frequently produces completely bogus results. In areas like here: http://www.openstreetmap.org/#map=13/56.7935/16.0168 http://www.openstreetmap.org/#map=13/62.7015/25.6678 the Corine based landcover data in my eyes has not connection to reality at all, it is factually simply wrong. I understand that the perspective to loose all the data and to be without any forest mapping until manual mapping has filled the gaps seems not so pleasant but i am pretty sure there are a lot of people from abroad who would be glad to help you with either manual forest mapping or importing better quality data in a way that is better maintainable and more compatible with manual mapping activity. However as long as the bad quality Corine data is there and meant to stay few people are interested in editing this mostly meaningless data. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
