But I have still some holes in the Mediterranean and in the Atlantic. There are still about 20.000 lines of severe errors resulting from sea generation similar to this: SCHWERWIEGEND (Polyline): ..\tiles\63240821.osm.pbf: Problem writing line (class uk.me.parabola.imgfmt.app.trergn.Polygon) of type 0x4a containing 93 points and starting at http://www.openstreetmap.org/?mlat=68.19019&mlon=16.44808&zoom=17 SCHWERWIEGEND (Polyline): ..\tiles\63240821.osm.pbf: Subdivision shift is 0 and its centre is at http://www.openstreetmap.org/?mlat=69.30766&mlon=20.07829&zoom=17 SCHWERWIEGEND (Polyline): ..\tiles\63240821.osm.pbf: deltaLat = -52078 I do not know how to "tweak the area.list". Can you tell me what to do exactly. Here is how I run the splitter: java -Xmx2800M -jar splitter\splitter.jar --max-nodes=700000 --no-trim --resolution=15 --geonames-file=cities15000.zip --output-dir=tiles Geofabrik\europe.osm.pbf 2>err1.txt --- http://wiki.openstreetmap.org/wiki/User:RheinSkipper -------------- next part -------------- A non-text attachment was scrubbed...
