Problemet med boundary=historical är att (om tillräckligt många göralösa kartnissar är i farten) det kommer att bli administrative med level 1-10, episcopal, political etc. som sedan alla ska slåss inom historical när de inte gäller längre. Iofs skulle man ju kunna sätta historical=administrative_4 för en boundary=administrative, admin_level=4 som inte längre gäller. Konrad torsdagen den 27 augusti 2009 19.45.41 skrev Einar Ryeng: > Hi.
