The duplicates from the BP import was intended not an accident, I intentionally didn't remove any existing data so that the data could be merged with existing information. > If youve been on-the-ground and surveyed the data for the tram stops and > simply wished to bulk upload verified data, that would be one thing, but > if you plan on removing possibly surveyed data, just for the sake of > importing a government supplied GIS list, I think the consequences > should be understood that you could be removing accurate data to replace > it with less-accurate data, unless you plan on reviewing/surveying every > node yourself? I agree, data should never be removed for the purposes of importing new data, there possibly a small amount of harm with duplicate data if people rely on it to be accurate, but in that case hopefully things will get worked out and merge the data. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
