Osmcoastline fixes small gaps in the data. I don't know of anything more coastcheck did. If anybody can give me any algorithms how to fix the data or "localize these problems", please do. > We're always going to have local coastline errors, so we have to figure > out how to recover from them I think we have to face it: The approach of allowing the user to add anything to the map and later fix it has failed. I strongly believed in it for the longest time. But I don't any more. We have to have stronger guarantees in the data structures and more checks in editors and in the API. Remember, the "coastline" is one of the easier problems there. Boundaries are much more complicated. Having spent months already on this "easy" problem, I don't see how our limited ressources are going to solve this if we don't tackle the problem in a very different way.
