I also get similar problems for some tiles (the result may depend on the splitter parameters). The problem is that there are several shoreline segments that do not end at the map boundary. Two examples are: - Rügen: The shoreline ends at the border to Poland. The current patch closes this segment since it's "nearly closed" (the distance between start and end is less than 0.1 * segment-length). This should result in the Polish part of the island (Swinoujscie) beeing flooded. This seems to be the best the algorithm can do since he doesn't know the Polish part of the shoreline cut off by osmosis.
i guess you mean usedom here, as rügen does not border poland. usedom is fine in my result with mkgmap1144+sea5, using the bbox cut out of the planet, which supports your argument, i guess.
If anyone has a good idea how to handle an incomplete shoreline, please let me know. Right know, it might be best to do the following: - get a country extract like germany.osm.bz2 from geofabrik, - calculate the boundary box, - use xapi or same other source to get the complete shoreline in this boundary box, - mix in the shoreline using osmosis, - use the result as input for splitter and mkgmap.
or take the planet or europe and cut a bbox from it? best, rj
