And by the way, if you wonder why a bunch of buildings are tagged as building=yes when that tag is meant for single buildings, I received a possible answer from Senegalese contributors: some have been taught to tag built-up areas and found that building=yes looks like a good choice to do that. The source of that teaching of a need to map built-up areas seems to be non-Openstreetmap cartography courses. And while we're at it, the next most frequent building tagging mistake: outlining the building on orbital imagery at roof level instead of base level... Explaining that pictures are not always taken from the vertical usually drives the point home. _______________________________________________ HOT mailing list [email protected] https://lists.openstreetmap.org/listinfo/hot
