Good evening, I'm using mkgmap r1466 and splitter r103. With my python script [1] I at first build .img files of various .osm.bz2 files and then put some of them into a gmapsupp.img file. I do _not_ regenerate the .img files each time I create a gmapsupp.img. For image files of maps which did not change I replace the family ID (binary search&replace, in libGarmin.py in the bz2; see [1]). The family ID is _unique_ for every single file. Now my problem is that some tiles are simply missing. I just tried to build an Europe map, and Germany lacks about half of all tiles. For available tiles there is a rectangle on the map when zooming out to 200km+ (on my 60CSx), and they are missing in Germany. Spain is completely missing. When I go to «Setup Map» on the 60CSx, I see lots of entries like: * OSM street map, Area 00010005, Jan 2010 * OSM street map, Area 00010000, Jan 2010 But at least as much of these: * , , Jan 2010 At least some of them do contain data. I could locate one of them in Germany. Question: What is going wrong there? Why are some tiles missing? Why is there an empty description (, , Jan 2010) for some tiles? Here the arguments I am using: SPLITTER --mapid=%s --status-freq=1 --geonames-file=%s %s MKGMAP --adjust-turn-headings --check-roundabouts --merge-lines --keep-going --remove-short-arcs --latin1 --route --make-all-cycleways --add-pois-to-areas --preserve-element-order --location-autofill=1 --country-name="%s" --country-abbr=%s -n %s %s MKGMAP (gmapsupp.img) --gmapsupp %s (with all .img files as argument) Any help is appreciated.
