[mkgmap-dev] Tile splitter and merged maps?

Tue Apr 26 18:00:27 BST 2011

Hi,

I created a merged map using osmosis:
$ ./osmosis --rb finland.osm.pbf --rb germany.osm.pbf --rb us-west.osm.pbf --merge --merge --wx DE_FI_USW.osm
which results in an uncompressed XML output map DE_FI_USW.osm of ~36G in size.

So this maps contains three different countries which do not necessarily have any overlap or connections, and bounding rectangles far apart from each other. 

Now I try to create one single gmapsup.img out of it using the tile splitter and mkgmap:

$ java -Xmx5000M -jar ../splitter.jar --mapid=63240345 --max-nodes=1000000 ../DE_FI_USW.osm

after this step I get a list of tiles which is suspiciously small, about 165M.

$ java -Xmx4000M -jar ../../mkgmap.jar --max-jobs --style-file=../../aiostyles/basemap_style/ --description='DeFiUs' --country-name=world --country-abbr=W --family-id=4 --product-id=45 --series-name='basemap' --family-name=OSM --area-name=W --latin1 --mapname=63240345 --draw-priority=10 --add-pois-to-areas --make-all-cycleways --link-pois-to-ways --remove-short-arcs --net --route --gmapsupp ../*.osm.gz ../../aiostyles/basemap.TYP

When I install the map, I only get map data for Finland, nothing shown for Germany nor US West. 

So looks like the tile splitter took into account only the first part of the merged .osm map. 
Am I doing something wrong here? Or is this an incompatibility or a possible problem with the tile splitter?

Thanks,

Dominik
