OK, I was wrong; I now tried to build a map with contour lines generated by GroundTruth (commands: "GroundTruth.exe contours --gridlat=1 --gridlon=1 -b=50,6,51,7 -o=50-6.ibf" and "GroundTruth.exe ibf2osm -i=50-6.ibf"). Then I built a map from the resulting .osm file with a mkgmap style just for polygons. The Lines were closed, but unfortunately, not around the corners of the source file (the contour lines' start and end points are exactly at 50/51 degree latitude and 6/7 degree longitude). GroundTruth doesn't add "bounds" to the osm file, but adding it manually doesn't change the result. As the contour lines generated by Groundtruth are always running clockwise around a hill, what needed to be done is closing them from a lines' endpoint clockwise around the tile edges until the startpoint is reached *or* the startpoint of another contour line with the same tags is reached, merging them, and continue. I don't know at all how much work would need to done to implement this behaviour... --Martin _______________________________________________ mkgmap-dev mailing list [email protected] http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
