With any circular way the first and the last nodes are the same. So to define a triangle you get four nodes in the xml. Those Swedish islands show up as errors because they are too small. Anything with a diameter of less than approximately 10 meter shows up as an error. -- m.v.g., Cartinus _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
