Hello list, I am the developer of the All in one Garmin map. http://wiki.openstreetmap.org/wiki/All_in_one_Garmin_Map At the moment I try to make some garmin maps for haiti with mkgmap. I use the geofabrik-extrakt of Haiti: http://labs.geofabrik.de/haiti/latest.osm.bz2 The Problem is, that I am not able to make the damn sea blue! Yes, I have read many many threads from this list about the generate-sea option, but things change rapidly and threads get really long. I thought that I understand how the different options work, but I am still not able to get this sea stuff to run. I use the latest mkgmap svn version. I used --generate-sea=extend-sea-sectors and defined a rule in polygons-style-file: natural=sea [0x32 resolution 10] But it doesn't work for Haiti. So I give the --generate-sea=polygons,extend-sea-sectors a try, and added a natural=land [0x27 resolution 10] rule in polygons file. I mapped a color with my typfile to this garmintype. But again - I couldn't get it to work. I really don't know what the problem is. The ocean looks like land. Please can somebody help me and tell me what to do to use the --generate-sea stuff correctly with haiti extract? Thank you! (And yes - I checked, that the whole coastline is present in the osm-file!) Christoph Sorry for my bad english...
