Hello, I tried to generate a map using the mdr version of mkgmap and I am a little bit confused. I use the following command lines: java -Dlog.config=..\logging.properties -Xmx3000M -jar mkgmap-r1260\mkgmap.jar --net --route --description="OSM Detroit area map" --mapname=10000001 Detroit_091003.osm java -Dlog.config=..\logging.properties -jar mkgmap-r1261mdr\mkgmap.jar --family-id=2804 --series-name="OSM Maps" --family-name="OSM Maps" --overview-mapname=Detroit --tdbfile --index 10000001.img First of all, I get some output that I do not quite understand: for section 11, use pointer size of 2 for section 10, use pointer size of 2 for section 7, use pointer size of 2 for section 5, use pointer size of 2 Then I get two img files: Detroit.img and Detroit_mdr.img. If I copy all the generated files to the appropriate directory I set up for MapSource, I can display the map but I have no index. I then tried to rename Detroit_mdr.img to Detroit.img. In this case, MapSource crashes at startup. Any help on what I am doing wrong here and how I can get a working index would be appreciated. Thanks, N.
