Well, according to the wiki (I know, who gives a flying fuck about the wiki) it says about natural=land: "Land that exists within another area, such as a lake. (i.e an island)." Spot on, I'd say. No one in their right mind would think that natural=land wasn't appropriate for island and other land masses. So I prefer to keep the default as natural=land. I like it. But just for you Felix, I have put in an option so you can specify the tag to use. Be creative.

Your example shows the coastline stopping short of the tile boundary, so it's not going to work. I can't see how the sea poly generation code can work around this - it's not psychic.

[mkgmap-dev] Commit: r1449: Provide an alternative to using a multipolygon when generating the sea.
Version 1449 was commited by markb on 2009-12-31 12:00:01 + (Thu, 31 Dec 2009) Provide an alternative to using a multipolygon when generating the sea. The --generate-sea option can now take a comma separated list of values: multipolygon - generate the sea using a multipolygon (the default behaviour so this really doesn't need to be specified). polygons | no-mp - don't generate the sea using a multipolygon - instead, generate a background sea polygon plus individual land polygons with tag natural=land. This requires a suitable land polygon type to be defined in the style file (suggested type is 0x010100) and the polygon must be defined in the TYP file as having a higher drawing level than the sea polygon type. no-sea-sectors - disable the generation of "sea sectors" when the coastline fails to reach the tile's boundary. An unrecognised option value or the value "help" will cause some help blurb to be printed. For backwards compatibility, with no values specified, the --generate-sea option should behave as it did before. ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev

Re: [mkgmap-dev] Baltic map looking good
Hi Charlie, > I see you've got lots of placeholder polygons in your TYP file. Do you > know what these are / what they do / why one might want to use them? If you use a TYP file, then you require either a polygon definition or a placeholder for every type of polygon that you want in the map. That's because those definitions specify the drawing level of the polygon. If you leave out the definition/placeholder for a given type of polygon, it will become invisible.

Re: [mkgmap-dev] Baltic map looking good
Hi Bennie, Thanks for the kind words. I attach the TYP file I am currently using. It's very simple, I think most people use more complicated files than that. I also attach the style files. They are fairly similar to the default files with a few tweaked values here and there. The seamark related stuff is experimental but will get submitted for inclusion in the default style when it settles down.
