Hi! there are quite a lot of broken (multi)polygons in the OSM data. I have started an effort to clean them up. You can find out more at http://area.jochentopf.com
I found that there are many problems with self-intersections in South Korea, often on forests. You can see this here: http://tools.geofabrik.de/osmi/?view=areas&lon=128.02487&lat=36.21680&zoom=8 Was there some kind of import? Can you, the Korean community, help with fixing them? How good is that forest data anyway? Is it worth cleaning up? I'd appreciate any information and help. If you are interested, I can also create special Maproulette challenges or create special data extracts or so to help the Korean community clean this up?
