are we? Can you point me to a place in the wiki where this is the case? I always thought of aerial imagery as an additional source for mapping, not necessarily the only one, (I admit I also have mapped sometimes based on aerial imagery alone, but I didn't feel like I was doing a perfect mapping in these cases). > Is that knowledge? > no, it clearly isn't. > Are map notes left by visitors to OpenStreetMap knowledge? > in most cases they are, in the end the mapper will have to decide if he can trust them or not. > How about incorrect or misspelled attributes left by other mappers: is that > sort of like looking at Bing? > this also is a gray area, it already happened to me that other mappers thought of (intentionally set) tags to be incorrect or misspelled and corrected them according to their interpretation (e.g. a bridge-area tag I invented to group bridge elements was misinterpreted). Often it would be better to keep stuff, because how could evolve new mapping schemes if everything is instantly turned into "standard" tags by leaving no trace of the new tags. "knowledge" is having been to a place and know what was there at that time, survey is going there right now and see what is currently there. cheers, Martin _______________________________________________ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
