On places where the tile borders are crossing this multipolygon mkgmap has problems with rendering (because the ends of the multipolgygon are way outside the tiles). Splitting up the multipolygon in smaller parts in osm seems not the way to solve these rendering problems because I think it's a bug in mkgmap that should be solved here instead of on osm. Any ideas?
I have understood that it is a splitter problem, not a mkgmap problem. I do not know the splitter. How many nodes are there along the multipolygon lines? Any nodes relatively near to the tile border? In Finland, I had a similar problem with Lake Päijänne, which is a single huge multipolygon. I have worked around this problem by moving my tile borders so that they do not cut through the lake.
