If you are using JOSM you can use the "Unglue Ways" from the Tools menu. This will duplicate the nodes to make the two overlapping ways independent. Don't know if this functionality is available in other editors.

I agree. I tried to fix the outline of a park that's just down the road from me. It's clearly incorrect when viewed on the satellite view in the editor, and I thought it would be a relatively simple task of dragging the nodes to match reality. But it turns out that the nodes down one side are shared with a river that's adjacent to the park, and down another side with a road that is almost, but not quite, directly adjacent to the park. Sharing nodes with that road makes the park look bigger than it actually is, and, more importantly, makes a building that, in reality, is on the boundary of the park appear to be wholly within it. I thought I could simply drag the nodes to the correct position, but I can't without also moving the road, which would be equally incorrect. It would make far more sense if the boundaries of the park were a single set of nodes and ways not shared with any other object. When I've got considerably more tuits to spare I may just do that - delete the park completely and then recreate it from scratch as a new object with its own nodes and ways. But, at the moment, I don't really have the time. So I've left it, and it continues to irritate me every time I look at it on the map :-) Mark _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
