Paul, I don't have anything technical to add but I have a suggestion or two:
1. If this is an area where the old multipolygons could be converted entirely to the new style- do you propose an automated edit to OSM? 2. If not, are there instructions we could do to OSM editors? If so, then perhaps this would be a good Advanced MapRoulette challenge. Most of the MR challenges are for beginners, but this might be a nice one for our more advanced user community. - Serge _______________________________________________ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev
