Re: [mkgmap-dev] Commit: r1198: Merge in the sea polygon patch from

Therefore I thought it might rather be a splitting / merging problem, than an originally broken coastline. I use --ignore-osm-bounds, could that mangle things? I also lately experience routing failure over tile boundaries, and trying with mkgmap 1243 my map failed to make last night.

I distinctly recall that you should not use --ignore-osm-bounds if you want to route between tiles. Regarding the sea polygons, I get the same problem on the Cloudmade extract of Ontario, Canada, when it is split but compiled without --ignore-osm-bounds. So this parameter is most likely the cause of your routing problems, but not your sea polygon problems. Cheers.
