Hi, I have a problem generating gmapsupp.img from two IMG files, previously generated by mkgmap. I'm probably doing something wrong, but I'm not sure what. Any help is appreciated. I have two 1 degree square IMG tiles for a location in Austria. 63275058.img contains the OSM street map, and 53275058.img contains the SRTM contour lines. The tiles cover the same area. You can get them from here: http://files.britishideas.com/index.php?dir=mkgmap/ If I run: java -Xmx1560M -jar ../scripts/mkgmap.jar --gmapsupp ./63275058.img then I can view the street map just fine. The file size is around 650kb. If I run: java -Xmx1560M -jar ../scripts/mkgmap.jar --gmapsupp ./53275058.img ./63275058.img then the contour lines show up but not the street map. The file size is around 12Mb. If I run: java -Xmx1560M -jar ../scripts/mkgmap.jar --gmapsupp ./63275058.img ./53275058.img then the file size is around 650kb. I haven't checked to see what that contains, but I expect it to be only contour lines. It seems that mkgmap is only including the first IMG tile in the generated gmapsupp.img. I've had this same approach (overlaying tiles) working for a larger region in Switzerland. Any ideas how I can solve this? I'm running revision 699 of mkgmap. There is no output to stdout or stderr from mkgmap when I run the commands above. thanks, Andy -- Andy PGP Key ID: 0xDC1B5864
