Thanks for the quick reply Gerd, Nope, same problem with 202. I don't know at all where the problem comes from. Too bad but Qlandkarte GT doesn't like the map either (shows blank only) - so I'm not sure why this happens. Maybe the single tiles are too big. The easternmost tiles span around 48°... Or the map should stop at 179° instead of 180°? I cannot remember, that an Asia extract from geofabrik, ever worked without that bug... Garmin did have a worldmap once, dunno if that could give clues to the max tile sizes? On 19.12.2012 16:47, Gerd Petermann wrote:

Felix,

I don't think that this is related to the use of a polygon, because that influences only the sizes and positions of the tiles. Do you think the problem is caused by the way how splitter r264 splits asia.osm.pbf? Does it work if you use r202 for splitting?

Well I tried out 264 without a polygon, and it's fixed and the empty area in the west is taken out. But Mapsource still cuts the map when zooming in at around 142 East. Is this the same when using a polygon? On 19.12.2012 09:57, GerdP wrote:

yep. I think the actual data is no more than 150° (east 31 to 180)- but the sea info around adds more to it so it starts already at W2°) On 18.12.2012 22:46, Gerd Petermann wrote: The error was in the new split algorithm. This is fixed with r264.

While fixing the error I found a general problem: Some objects in the OSM database are crossing large areas, eg. "The Arctic Circle" http://www.openstreetmap.org/browse/way/162812278

Since the asia extract contains this way completely, splitter creates a tile that covers almost whole Europe if you don't provide a bounding polygon. I've attached the results, once with using --polygon-file=asia.poly, once without.
