Can I tell the splitter to ignore the map's bounding box altogether and find its own? Any other ideas how to make it take into account the whole merged map?
Can you split each extract separately and then tell mkgmap to produce a map from the tiles generated by the three splitter runs? IIRC, I tried producing a combined map of finland.osm.bz2 and estonia.osm.bz2 in 2009, when I visited Tallinn. It sort of worked, but routing did not work in Tallinn. I did not investigate or experiment further. It could also have been due to bad map data; I only keep Finland tidy. :-) In 2010, I loaded just the Estonian map and then just a small area where I moved, for adding some pedestrian crossings and sidewalks and the like. You could use my hand-made areas.list for Finland. It tries hard to get a nice generate-sea. It also avoids splitting the Lake Päijänne multipolygon. One of your tile borders slices the lake. The tile border should be a little more west near the line Jämsä-Kuhmoinen-Padasjoki. Best regards, Marko
