Hi Thomas I've just loaded the relation 1754729 with JOSM. JOSM validation reports no errors, but mkgmap (direct, no splitting) gives errors: WARN: uk.me.parabola.imgfmt.app.Area lakeLadoga.osm: Area.split 2852864 1400832 2854912 1402880 res 11 can't 2 1 WARN: uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation lakeLadoga.osm: Multipolygon http://www.openstreetmap.org/relation/1754729 [ele=4.84, int_name=Ladoga lake, name:en=Lake Ladoga, name=Ладожское озеро, natural=water, type=multipolygon, water=lake] contains errors. WARN: uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation lakeLadoga.osm: Polygon 4611686018427403156(4P)(259078070[118P]) carries role inner but is not inside any other polygon. Potentially it does not belong to this multipolygon The area.split WARN happens when there are too many object (points/lines/polygons) in 1 resolution unit. The other error is as described. I notice that this relation was edited a couple of days ago so maybe someone is fixing or creating problems. I'll try again in a few days and investigate more deeply.

Hi Ticker, I found : osmium-tool and splitter works proper. I can the splitted <12345678>.osm.pbf open and render in JOSM. JOSM shows the part of the multipolygon 1754729, which is inside the boundary of the polygonfile for splitter. I assume, mkgmap has the problem. But sorry, I am not a good programmer and can not do deeper investigation or find a solution. If you interested, I can give you my polygon and the <maptile-number>.osm.pbf.

Hi Thomas
I get similar problems just using
https://download.geofabrik.de/europe/britain-and-ireland.html
directly. The relations that cause the problem are not within the above combined territories but excluding them would required a much more complicated shape to define the download area.

Hi Ticker, i made further investigation. You are right.: the MultiPolygonRelation 1754729 ('Ladoga sea') was cut by ectract Scandinavia from europe-latest.osm.pbf using osmium-tool . I am not sure, but means this, that osmium can not write a proper ectract, if such Relation must bee split ? This means also, osmium has a bug ? I must check my osmium version... regards Thomas Am 02.09.2024 um 10:30 schrieb Ticker Berkin:
Hi Thomas
It isn't related to AngleChecker.
I notice that both these relations have been changed in the last couple of days so maybe they were faulty.
The large one is on the boarder with Scandinavia and it is likely that the map extraction download only had part of it and this gives rise to this type of error.

Hello , I use mkgmap-4921 with patch from Ticker Berkin - Angelchecker-V6. With that i get in Scandinavia following error : Internal Error Failed to render MultiPolygonRelation 1754729 and 304507. Rel. 1754729 is 'Ladoga'- sea with 5 226 Elements. Rel. 304507 is Multipolygon=water, 171 Elements. I assume the error ist not specific to the patch...and more common.. How to avoid this ? regards Thomas _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
