Hi, i use the analyseur osmose (https://gitorious.org/osmose/backend/) to detect the ways that - same geometry (but not necessary same nodes) - same tags
correction is made by josm - fix duplicated ways - fix orphaned nodes I have not analyzed the causes of these duplicates. I delete a lot of ways and node everywhere on the planet, also this explanation seemed necessary on this list didier _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
