I believe this kind of "fix" should not be performed, it leads to problems if this kind of mapping was done on purpose, e.g. because of some properties being different. Not applying "magic guesswork" also leads to more predictable behavior and ultimately to mappers fixing the representation in case it was wrong. cheers, Martin _______________________________________________ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev
