Hi, I'm trying to build a map of The Netherlands and got some problems with rendering the administrative borders correctly. Some parts were related to broken relations between tiles, but the major one was caused by a complex relation of enclaves/exclaves of Baarle in the south of the country. I examined this area more closely and narrowed the problem down to this situation, where I cant render the map correctly with mkgmap: A = one big outer ring (the Dutch municipality of Baarle-Nassau), B1, B2 = some islands inside (Belgium territory, role=inner) C= Within some of those islands there are polygons (Dutch, role=outer) It goes wrong with those outer polygons within the inner polygons. Simplification looks like this, where the two vertical border lines are not supposed to be there: http://img63.imageshack.us/img63/1002/bordersnl5.jpg The relation can be found at http://betaplace.emaitie.de/webapps.rel onId=47798 There are no gaps or faults within the relation as far as I can see. I put this question and a few examples of my map also on the forum at http://forum.openstreetmap.org/viewtopic.php?pid=59370 Thanks, Minko
