And as is my image I wanted to generate. I was using the ohio file from CloudMade, downloaded today. kentucky also. The other files work well. Except for error messages like SCHWERWIEGEND (LineSplitterFilter): Way (US:WA14 State Route 14, http://www.openstreetmap.org/browse/way/5930357) has a max dimension of 32767 and is about to be split (routing will be broken) or SCHWERWIEGEND (MapSplitter): Area too small to split at http://www.openstreetmap.org/?lat=39.73167&lon=-74.64532&zoom=17 (reduce the density of points, length of lines, etc.) -- but at least mkgmap does not crash here. Error message below, have fun.
