You will also hear folks suggest tag the highway as it exists, then add the highway to a boundary relation for the admin_level. When applied correctly, this makes corrections to the road geometry simple, makes the boundary follow the corrected road without a hassle, and is an excellent use of a relation. This is not an argument to put the boundary on the road if the boundary does not belong on the road. The same benefits would apply for a boundary that follows a river or other exiting feature. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
