Hi Mike, I can try to find out what's wrong but I would need a lot more details about your map creation process. Could be an error in mkgmap or in the OSM data or in the --levels option or in the --min-size-polygon option or --polygon-size-limits or ...

It looks similar to the problem reported on Feb 18 2017 with "Terraced/pixellated coastline with --precomp-sea" as the title. I am not using --precomp-sea, but the problem I am getting is also in the sea outline. NopMap indicated that his problem was fixed in r3819, however, I have downloaded the source to that version and compiled it, and it exhibits the same problem for me.

Are you sure that you didn't change mgkmap options like --levels or the style or the typ file? Do you still have a map which looks better? In that case you should find the string mkgmap in the img file, e.g. "mkgmap-r4431" Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Mike Baggaley <mike@tvage.co.uk> Gesendet: Montag, 27.

Obviously some reduction in accuracy is expected at lower zoom level, but not these artefacts. I'm not sure when this started happening but believe it was some time ago. I can't seem to find the old releases to try previous versions, http://svn.mkgmap.org.uk/mkgmap/releases/ just shows me an empty folder. Can you point me to the correct download folder that contains the previous jar files, and/or let me know if this is a known problem, and if so whether there is a workaround?
