Re: [Talk-ko] Broken (multi)polygons in Korea
Quite difficult i must say. http://maproulette.org/map/2420/2050730 Just to say that the riverbed is mapped in a detail that is useless because it represents the waterlevel and riverbed at the time of the satellite image. There are so many occlusions and little islands, it's almost easier to start over. The outer riverbank has now 5 outer relations, not sure if this is supposed to be like that. I used JOSM to merge the overlapping polygons and then ID rying to fix the islands that disappeared in the process. I think I better leave this kind of stuff to others.

Re: [Talk-ko] OSM Talk-ko must use English?
By the way, I already mentioned this on the list, but if someone can write a short paragraph in Korean with a description of the mailing list purpose and a statement that Korean and English language is welcome I can put it on the list subscription page. I will include an English translation. One paragraph, three or four sentences would be fine.
