I am trying to make a testmap and look at it in RoadTrip. The creation process goes smoothly, and the gmapibuilder output looks reasonable. I can use MapManager to add the map, but then RoadTrip crashes when I try to select it. A similar process to build real maps (from cloudmade extracts, with the splitter) with the same mkgmap.jar produces maps that work in RoadTrip. I have not yet tried this map on a gps receiver. Is there anything obvious I am doing wrong? echo "test-map:all-elements" export BASE_LAT=42.3 export BASE_LONG=-71.1 time \ java \ -enableassertions \ -Xmx2048m \ -jar mkgmap.jar \ --overview-mapname=63500000 \ --mapname=63500001 \ --description="OSM_test" \ --country-abbr="US" \ --country-name="United States" \ --region-abbr="MA" \ --region-name="Massachusetts" \ --series-name="OSM_test_series" \ --family-id=402 \ --family-name="OSM_test_family" \ --product-id=14 \ --series-name="OSM_test_series" \ --area-name="OSM_test_area" \ --tdbfile \ test-map:all-elements > OUT.04.mkgmap 2>&1 echo "options not used:" \ --remove-short-arcs \ --add-pois-to-areas \ --route \ mkdir -p GMAPI-TEST echo "GMAPI-TEST:" time \ /Users/gdt/SOFTWARE/GMAPIBUILDER/gmapi-builder/gmapi-builder.py \ -o GMAPI-TEST \ -t 63500000.tdb \ -b 63500000.img \ -v 6350*.img \ > OUT.05.gmapi-test 2>&1
