Hi Wanmil, I've enabled logging and I see now 4 files with mkgmap.log.0, 1, 2 and 3 without any relations in it: http://mijndev.openstreetmap.nl/~ligfietser/diverse/mkgmap.log.zip Maybe my logging.properties parameters are not correct? # The default level FINE, WARNING, INFO, SEVERE .level=FINE #handlers: java.util.logging.ConsoleHandler handlers: java.util.logging.FileHandler # package or class name with .level appended and then the level uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation.level=FINE # For ConsoleHandler java.util.logging.ConsoleHandler.level=WARNING java.util.logging.ConsoleHandler.formatter=uk.me.parabola.log.UsefulFormatter # For FileHandler java.util.logging.FileHandler.level=FINE java.util.logging.FileHandler.formatter=uk.me.parabola.log.UsefulFormatter java.util.logging.FileHandler.limit=5000000 java.util.logging.FileHandler.count=4 java.util.logging.FileHandler.pattern=mkgmap.log java.util.logging.FileHandler.append=false ---------- Wanmil wrote: If you assume that the multipolygon algorithm has a problem you should change the log level of the Multipolygon class: uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation.level=FINE Enabling the logging is described at http://wiki.openstreetmap.org/wiki/Mkgmap/dev#Enabling_Debugging You can search the logfiles for the relation id and check what the multipolygon code is doing. The logfiles get big so it might be good to compile the relevant tiles only. If you have questions just send the logfile.
