I have been trying for a while to build my own maps with mkgmap, and was getting bad maps into RoadTrip. I figured out what I was doing wrong and thought I'd share it. I had run the splitter and then mkgmap, creating a gmapsupp.img overall map file in addition to all the tiles. I ran gmapibuilder with the gmapsupp.img instead of the individual tiles, and this produces a totally broken gmapi.
I spiffed up the caveats section under command line to try to warn others: http://wiki.openstreetmap.org/wiki/Gmapibuilder Here's what I'm doing now, and it seems to work except routing is broken on my vista hcx, perhaps due to some messed up ways in the mass data. #!/bin/sh INPUT=$1 if [ "$INPUT" = "" ]; then INPUT=massachusetts.osm fi cd $HOME/OSM || exit 1 if true; then rm -f 6324* 40000001.* areas.list template.args java -Xmx2000m -jar splitter.jar \ --max-nodes=500000 \ $INPUT \ > OUT.01.splitter 2>&1 ed template.args <<EOF g/^description:/d w EOF fi # --net is implied by --route java -enableassertions \ -Xmx2048m \ -jar mkgmap.jar \ --max-jobs=1 \ --gmapsupp \ --tdbfile \ --series-name="OSM_gdt_series" \ --family-name="OSM_gdt_family" \ --area-name="OSM_gdt_area" \ --overview-mapname=63240000 \ --family-id=632 \ --product-id=1 \ --country-abbr="US" \ --country-name="United States" \ --region-abbr="MA" \ --region-name="Massachusetts" \ --description="OSM_gdt" \ --route \ --add-pois-to-areas \ --remove-short-arcs \ -c template.args \ > OUT.02.mkgmap 2>&1 # --ignore-osm-bounds \ # --mapname=63249900 \ mkdir -p GMAPI /Users/gdt/SOFTWARE/GMAPIBUILDER/gmapi-builder/gmapi-builder.py -o GMAPI -t 63240000.tdb -b 63240000.img -v 6324*.img > OUT.03.gmapi 2>&1 ls -lh gmapsupp.img
