[mkgmap-dev] It's clearly a bug in the splitter

Wed Oct 17 12:22:13 BST 2012

Well, I tried to render luxembourg using the osm.pbf file from 
geofabrik, without splitting it, and than the map is good. As soon as I 
split it (also if the output is only one single osm.pbf tile),
I have missing portions in the map.

I use the following commands for splitting (newest splitter):
java -Xms4000m -Xmx6800m -jar splitter.jar --max-nodes=1250000 
--output=pbf --overlap=5000  --geonames-file=cities15000 
--description=luxembourg --mapid=64230000 luxembourg.osm.pbf

And this is the splitter output:
cache=
description=luxembourg
geonames-file=cities15000
legacy-mode=false
mapid=64230000
max-areas=255
max-nodes=1250000
