Hi. Just after splitter reports that it stats with the second country (estonia in lower case is the country name within the polygon file). --resolution=15 combined with --max-nodes=75000 did not change... Some of the output: Rounded map coverage is (55.634765625,19.7314453125) to (60.029296875,28.2568359375) Splitting nodes into areas containing a maximum of 75 000 nodes each... splitting distinct part of latvia Highest node count in a single grid element is 83 999 Highest node count in a single grid element within the bounding polygon is 77 110 ... continues..... Then splitter reports "splitting distinct part of estonia" thereafter: java.lang.NullPointerException at uk.me.parabola.splitter.solver.DensityMap.getNodeCount(DensityMap.java:156) at uk.me.parabola.splitter.solver.EnhancedDensityMap.prepare(EnhancedDensityMap.java: 83) at uk.me.parabola.splitter.solver.EnhancedDensityMap.<init>(EnhancedDensityMap.java: 43) at uk.me.parabola.splitter.solver.SplittableDensityArea.prepare(SplittableDensityArea.java: 339) at uk.me.parabola.splitter.solver.SplittableDensityArea.split(SplittableDensityArea.java: 177) at uk.me.parabola.splitter.solver.SplittableDensityArea.split(SplittableDensityArea.java: 237) at uk.me.parabola.splitter.solver.AreasCalculator.calcAreas(AreasCalculator.java: 228) at uk.me.parabola.splitter.Main.split(Main.java:227) at uk.me.parabola.splitter.Main.start(Main.java:121) at uk.me.parabola.splitter.Main.main(Main.java:81) I can add the full output if it may be of any use.

Hi Karl,
I've not tried it yet. What is the error message from splitter? When experimenting with small files it sometimes makes sense to increase the resolution (14 or 15) and lower the --max-nodes values to get closer to a large scale result (like > 100 tiles or so)

Hi. I have asked long ago about this particular problem i have and it was long time ago i last tried, but now i did again. It relates to splitter and usage of --polygon-desc-file=
This is how i have tried: 1. Download data for Estonia and Latvia. https://download.geofabrik.de/europe/estonia-latest.osm.pbf https://download.geofabrik.de/europe/latvia-latest.osm.pbf
2. convert to o5m and combine osmconvert estonia-latest.osm.pbf -o=estonia-latest.osm.o5m; osmconvert latvia-latest.osm.pbf -o=latvia-latest.osm.o5m; osmconvert estonia-latest.osm.o5m latvia-latest.osm.o5m -o=ee_lv.o5m;
3. Prepare an osm-polygon file with one area for Estonia and one for Latvia. (file attached)
4. Run splitter: java -Xmx2000m -jar ${SPLITTER} \ --polygon-desc-file=./polygon_ee_lv.osm \ --output-dir=ee_lv/splitted/ \ --max-nodes=750000 \ --no-trim \ ee_lv.o5m
While running this is seems like the Latvia part is fine, but the Estonia crashes.
The error message doesn't say much (that i understand). But maybe it makes some sense to you? I imagine something is wrong with the polygon file, but i dont know what.
The polygon files is partially made in JOSM and partially manaully to re-use the same segments/edges which belong to both countries. (I could see that Gerd was using this concept in some example file for Germany and the alps, but i could not add two ways over one edge in JOSM, so i made manual chanegs in the file). I tried also making two separate boxes, one for each country, but that was just as bad (not reusing edges).
Anything that could be suggested that i change or try?
PS. i am trying this on small scale for two smaller countries, later i will apply it because i need to split europe in parts of max 4GB.
