Betreff: [mkgmap-dev] Problem with splitter: Failed to find a correct split

Hello together,

I'm running into a problem with the splitter (r435 aswell as r427) when splitting the US_ALASKA file downloadable from Geofabrik.

The exception is:
Warning: No solution found for partition (49.7900390625,-179.9560546875) to (73.828125,180.0) with 6'702'717 nodes
uk.me.parabola.splitter.SplitFailedException: Failed to find a correct split
        at uk.me.parabola.splitter.SplittableDensityArea.split(SplittableDensityArea.java:152)
        at uk.me.parabola.splitter.SplittableDensityArea.split(SplittableDensityArea.java:196)

        at uk.me.parabola.splitter.Main.start(Main.java:187)
        at uk.me.parabola.splitter.Main.main(Main.java:157)

The complete command line with the splitter call is:
java -Xmx1536M -jar D:/fzk/develop/fzk-mde-garmin/Freizeitkarte-Entwicklung/tools/splitter/splitter.jar --max-threads=2 --geonames-file=D:/fzk/develop/fzk-mde-garmin/Freizeitkarte-Entwicklung/cities/c

The pbf source file comes from:
http://download.geofabrik.de/north-america/us/alaska-latest.osm.pbf

The osmconvert statistics about that file is:

Interesting to mention:
- splitter exception mentiones a complete different coverage area than osmconvert statistics.
- the area is near -180 / +180... always complicated.

Do I miss something ? All other pbf's I've tried are splitting properly without any problems. Do I need to change something in the arguments ? Or is it a simple problem of the actual pbf file ?

Any ideas are very welcome....

Cheers
Patrik
