I'm trying to map administrative boundaries (level 9 and 10) in #stockholm on #openstreetmap, but I'm not so sure what is the best tool for the job. Does anyone know of a tutorial/etc that could be useful for a not really beginner but also not expert mapper like me?
Another problem that I'm having is that for, e.g., Solna kommun, I can't seem to find what the level 10 areas even are (do they even exist?). Is there an authoritative source I can get the data from?
