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.
Side note: why not --wb DE_FI_USW.osm.pbf? Splitter can process osm.pbf.
So this maps contains three different countries which do not necessarily have any overlap or connections, and bounding rectangles far apart from each other.
I would not bee too sure about that. I have come across (and split) multipolygons that had members in Finland but also in Germany, Spain or North America.
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.
What kind of coordinates do you see in the areas.list? Could it be that splitter is misinterpreting the bounding box?
Am I doing something wrong here? Or is this an incompatibility or a possible problem with the tile splitter?
For what it is worth, about a year ago I experimented with merging a section of the Baltic Sea coastline to the (then) finland.osm.bz2 from Geofabrik, so that the coastline would extend to every tile border. I did not get the merging to work. Best regards, Marko
