Correct. Information would have to be on individual ways, because say two identical parallel ways close to one another should have to be reduced to one way. Even more: road network pruning is scale dependant, so additional information could be multiplied by the number of scales required. Note: additional information on ways would have to be adjusted even if the way itself does not change but information in surroundings change. For example forest path can be placed on a map (in a middle scale) but later removed after a parallel road is built alongside the path (say 50m away from the path even without touching/influencing the path itself). Therefore such tagging would go against OSM conventions. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
