Well for me any lake marked with natural=coastline is plain wrong. Just people mapping for the renderers.
Yes, but some controversy arised when I converted Saimaa (the biggest lake of Finland) to a number of multipolygons. It was simply too big (thousands of ways) for a single multipolygon, and even as it is now, Osmarender and OpenCycleMap are having trouble, especially around Kuopio.
A better solution would be, to simply have higher limits of how big a polygon needs to be at a certain resolution. As well as the DP filter aggressiveness, at resolutions lower than 20, we would need more aggressive dropping of small polygons. Dropping coastline already at 18, is superstrange if one is using --generate-sea=polygons.
Agreed, it would be nice to see all big lakes at resolution 12. Could tuning the DP filter help realize that? Marko
