As you know the Great Lakes have a right of continuance in being tagged as coastline however you should keep in mind that not having a multipolygon relation tagged natural=water representing these lakes also has disadvantages, and having relations/nodes tagged place=sea or place=lake is awkward and you can't really expect geocoders, renderers and other programs to make a special case here. By the way even if the lakes are tagged as coastline tagging the US-Canada boundary within the lakes maritime=yes is not correct. > Technical advice is welcome, e.g. how to easily find island ways that > go clockwise (water on the left) Yes, that's a tricky one - i don't think there are that many islands not yet tagged coastline though. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
