True... maybe changing tags on the ways isn't appropriate. However, if a closed loop of identically-named ways with other matching ways extending from the loop is detected, it's almost certainly fair to mark it as a likely bug for a human to review. -- Peter Budny \ Georgia Tech \ CS PhD student \ _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
