Hi all, I stumbled over a problem in mkgmap when I build a map with my bikeroute style (an overlay-map to highlight bicycle routes) I get a non-functional map for bigger areas. There is no error message during the build process, just the resulting map file is faulty. When I remove some tiles the map is OK. It seems to be related to the size of the map, not the data itself. I composed a sample that produces a good and a bad map. Unfortunately the files are rather big. The smallest example I could build is ~600MB. I will provide a link to the example once the upload has finished. <http://gis.19327.n8.nabble.com/file/t339543/BAD.bmp> <http://gis.19327.n8.nabble.com/file/t339543/GOOD.bmp> The faulty map get displayed in the Garmin's map list as "Map data (c) OpenStreetmap" while the good map get displayed correctly as "Bikeroute" When I remove one tile from the build the map is OK. It does not matter which one I remove. So there is no error in one single tile. It has to be a more complex problem.
