I found this peculiar as well - the most likely explanation seems to be that the quality of building detection and especially of building geometry generation (if that is being done at all) is probably quite bad and by not using the building data directly you can kind of disguise such deficits. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
