Hi Christoph, With r3994 I've changed the default style to ignore those large islands. I think it was already discussed here and I simply forgot to commit the change: http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2016q3/025051.html Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Christoph Karl <pampelmuse@gmx.at> Gesendet: Samstag, 19.

I have done this with: /usr/java/jdk1.8.0_144/bin/java -Xmx8G -jar ./mkgmap-r3993/mkgmap.jar -- gmapsupp karten/corse-latest.osm.pbf But the colouring of the landscape is not correct. See "corse_wrong_colour.png" Compared to "bremen_correct.png" Screenshots are made from qlandkartegt Version 1.8.1. I also tried to use "--precomp-sea=./karten/sea.zip", but this just colours the surrounding sea. Do you have any ideas? Thank you Best Regards Christoph
