[mkgmap-dev] Proof of concept for better sea in overview map

Sat Jun 12 10:02:05 BST 2021

I just updated australia-oceania from geofabrik again - old version was 09
June 2021. I have not updated osmconvert.exe a long time - but it cannot
create data out of nowhere...

D:\openmtbmap\osmpbf_geofabrik\australia-oceania-latest.osm.pbf
C:\openmtbmap\osmconvert.exe --drop-author --drop-version
D:\openmtbmap\osmpbf_geofabrik\australia-oceania-latest.osm.pbf
-o=C:\openmtbmap\osmpbf_geofabrik\australia-oceania.o5m

start /low /b /wait java -XX:+AggressiveHeap -Xms15000m -Xmx54000m -jar
C:\openmtbmap\splitter.jar "--precomp-sea=C:\openmtbmap\maps\sea.zip"
--max-nodes=1000000 --max-threads=8 --output=pbf "--keep-complete"
--route-rel-values=mtb,bicycle,foot,hiking --max-areas=4000
--geonames-file=C:\OpenMTBMap\maps\cities5000.zip
--description=australia-oceania --mapid=65340000
C:\openmtbmap\osmpbf_geofabrik\australia-oceania.o5m  1>NUL
   max-nodes value 1000000 is far above highest node count 209465 in single
grid element, consider using a lower resolution

And it is virtually identical... Maybe it is because I use precomp-sea also
for splitter?
