I'm fine with that. Wikipedia says "National Forest is a classification of federal lands in the United States." This doesn't mean that the name National forests implies a forest tag (it's just an administrative classification). Further Wikipedia says "National Forests are largely forest and woodland areas". I guess this is why you want to use the landuse=forest tag as a "first approximation" with the intention that mappers will go ahead and modify (exclude subsets) appropriately. The problem with this approach is that it makes further editing hard and discouraging (exactly the opposite of creating forward momentum). When the landuse=forest tag is part of the administrative boundary one needs to create complicated mulitpolygones for any further refinement of the map. This stops (or at least discourages) me as a contributer from making the map better. Moreover the generic landuse=forest tag adds no new information that isn't already there with the name "National Forest" and the administrative boundary. It is OK to do "first approximations" when mapping, but one needs to make sure that these will not seriously hinder further refinement. For this reason I am against general tagging of vast areas simply because they are "largely forests". Imagine somebody tagging Finnland (75% forests) as landuse=forest [or natural=wood]. In this sense my "alternative proposition" is remove the generic landuse=forest tag and thus encourage OSM contributors to go ahead and build a beautiful map. _______________________________________________ Talk-us mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-us
