I am trying to make a map that uses the English names for provinces in SE Asia. The province shown on my Zumo for POIs in Bangkok is a "Latinized" กรุงเทพมหานคร rather than "Bangkok" from the name:en tag. The relation in question (92277/6) is tagged name=กรุงเทพมหานคร and name:en=Bangkok. I use the --latin option when I compile the map. I extract boundaries with: bin\Osmosis.bat --rb asia.osm.pbf --tf accept-ways boundary=administrative --tf accept-relations boundary=administrative --used-node --write-pbf boundaries.osm.pbf omitmetadata=true I compile boundaries with: java -ea -Xmx1000m -jar mkgmap/mkgmap.jar --createboundsfile=boundaries.osm.pbf --location-autofill=bounds name-tag-list=name:en,name What am I doing wrong? Do the tags on the boundaries play a role or are only the tags on the relations used? What would be the way to check all admin4 boundaries' tags in SE Asia? The boundaries seem to be tagged inconsistent.
