Hi Gerd, Great! Thanks for the fast fix! No missing multipolygon with release 4574. I was afraid you would say that this is such a rare situation that the check was "intentionally left out because of performance issues" :) Ranko On 12.09.2020. 8:09, Gerd Petermann wrote:
Hi Ranko,
thanks for reporting. Strange that such an obvious error did not show up before! Problem is in the method MultiPolygonRelation.removeWaysOutsideBbox(). I am working on a fix.
Gerd

Hi Gerd,
Recently I discovered a missing forest "triangle" on my map (see attached screenshots). I am using the same mkgmap/splitter (4551/597) versions as before, but obviously OSM data changed so splitter generated a slightly different areas.list
The forest in question consists of two very large multipolygons:
https://www.openstreetmap.org/relation/1431438 https://www.openstreetmap.org/relation/4433469
Both relations cover the map-tile area, but mkgmap creates no polygon for the second one. It supose it doesn't get detected in mkgmap because it has no nodes in the area (splitter has no such problem: it detects the multipolygon and includes it in the output file).
I am including my test data: - forest.osm.pbf - contains only these two relations (or use croatia-latest.osm.pbf extract from Geofabrik :) - areas-test.list - area in question - forest-typ.txt - simple typ file to display forest (not really needed)
test code:
java -jar splitter.jar --split-file=areas-test.list forest.osm.pbf java -jar mkgmap.jar -c template.args forest-typ.txt --gmapi --remove-ovm-work-files
Splitter includes both relations in the 88010024.osm.pbf, but mkgmap includes only the first one in the generated 88010024.img file.
regards, Ranko
