I suppose it has something to do with >179°?? java -Xmx6600m -jar splitter.jar --max-nodes=800000 --output=pbf "--keep-complete" --max-areas=255 --geonames-file=cities15000 --description=as asia.osm.pbf Splitter version unknown compiled 2012-12-18T12:44:14+0100 cache= description=asia geonames-file=cities15000 keep-complete=true mapid=65400000 max-areas=255 max-nodes=800000 max-threads=8 (auto) mixed=false no-trim=false output=pbf output-dir= overlap=-1 polygon-file= problem-file= problem-report= resolution=13 split-file= status-freq=120 stop-after=dist write-kml= Elapsed time: 0s Memory: Current 122MB (2MB used, 120MB free) Max 5866MB Time started: Tue Dec 18 18:24:02 CET 2012 Map is being split for resolution 13: - area boundaries are aligned to 0x800 map units (0.0439453125 degrees) - areas are multiples of 0x800 map units wide and high Processing c:\openmtbmap\osmpbf_geofabrik\asia.osm.pbf Bounding box -179.99990000000003 -17.06773 179.99990000000003 84.52666 10'000'000 nodes processed... id=345469396 20'000'000 nodes processed... id=602633323 30'000'000 nodes processed... id=735433109 40'000'000 nodes processed... id=766952699 50'000'000 nodes processed... id=929389508 60'000'000 nodes processed... id=1054713652 70'000'000 nodes processed... id=1169860237 80'000'000 nodes processed... id=1244176605 90'000'000 nodes processed... id=1296405869 100'000'000 nodes processed... id=1346975878 110'000'000 nodes processed... id=1401150913 120'000'000 nodes processed... id=1451567888 130'000'000 nodes processed... id=1502517075 140'000'000 nodes processed... id=1594119652 150'000'000 nodes processed... id=1667582161 160'000'000 nodes processed... id=1730324902 170'000'000 nodes processed... id=1799260316 180'000'000 nodes processed... id=1864129020 190'000'000 nodes processed... id=1943914135 200'000'000 nodes processed... id=2017718514 in 1 file Time: Tue Dec 18 18:25:32 CET 2012 Exact map coverage is (-17.067711353302002,-179.9998927116394) to (84.52664136886597,179.9998927116394) Rounded map coverage is (-17.0947265625,-180.0) to (84.55078125,180.0) Splitting nodes into areas containing a maximum of 800'000 nodes each...
