[mkgmap-dev] splitter and josm problem

From Gerd Petermann GPetermann_muenchen at hotmail.com on Sat Apr 1 11:25:04 BST 2017

Hi Thomas,

the problem was caused by your manually changed split file which contained small overlaps. Do you still use that one?
I think I fixed the problems with that one in r440.
Or maybe you created a new one which causes new problems?

Hi Gerd, the old problem exists till now. I splitt europa-latest-osm.pbf using splitter r-580. But splitterr-580  do not proper splitt the multipolygon ("Schloßteich", 3 Elemente) [Kennung: 59.766] . The mp has tags: name=Schloßteich; natural=water, type=multipolygon. This mp has element Rolle=outer; 23387723 (86 Punkte) [Kennung : 23.387.723]. The error ist : all 86 nodes has no tags , but it should have the tags natural=water and name= Schloßteich from the multipolygon. See picture : img2ms.de/bilder/wrongsplit.jpg

split.list for this file : 50000707: 2367488, 593920 to 2390016, 634880

maybee you can have a look at that ? center of map is at lat 50.8419209  lon 12.914752

Hi Thomas,

I can open the big file in JOSM with JRE option -Xmx6G.
Besides that the mp relation is 59766, the id 233877233 belongs to the outer
And yes, splitter seems to drop the relation in the large file. I'll try to
find out

Hi at all, i am using splitter r429 and mkgmap r3695. Normally it works
perfekt. But now  it gives me a problem with multipolygons. I downloaded
and splitt latest-europe.osm.pbf from geofabrik, ---> splitt it with
splitter r429 for testing to 2 tiles, a big tile 80000707.osm.pbf and a
small tile 80000011.osm.pbf. The small tile is inner the big tile. Both
tiles contains the area with the multipolgon ID 23387723. Then compile
it for testing  separatly with mkgmap r3695. If the input is the small
tile 80000011.osm.pbf, it compile the img correct, *spezially the
multipolygon ID 233877233 (tags : name=Schloßteich; natural=water;
type=multipolygon) is present as 0x3c in resulting img. *See
img2ms.de/bilder/multipolygon-good.jpg. It is the blue lake name

If i compile the big 80000707.osm.pbf, the resulting img has not this
area . *It seems for me, as if the multipolygon ID 23387723 is ignored*.
See img2ms.de/bilder/multipolygon-wrong.jpg. In both cases i use ident
style. It makes no different, if the default style or my own style is

I tried to found out, if the splitter produce the multipolygon in the
big 80000707.osm.pbf, but JOSM v11223  can not load the big (~25MB)
80000707.osm.pbf. : JOSM --> open file 80000707.osm.pbf--> 'Lese
OSM-Daten...'--> and a few minutes later the MessageBox close, but the
osm.pbf shows not on the screen. Has the JOSM-plugin 'pbf: Version
32865' any limitations ? My PC has 6 GB RAM, 64 bit Windows10.
Any hints are welcome. Download for both 80000*.osm.pbf :
