I extended the parser so that there can be multiple base-style declarations within a style. I was thinking of refactoring the following from the default style and adding these to styles/default/info: base-style: country-specific # mkgmap:country etc. base-style: waters # water polygons and lines base-style: boundaries base-style: contours base-style: landuse # natural=*, landuse=* except water features base-style: leisure # most leisure things base-style: aero # airports, runways etc. base-style: car # parking, fuel stations base-style: restricted # military, prisons, etc. base-style: manmade # building=*, man_made=* base-style: commercial # shop=*, paid-for amenity etc. base-style: services # public or non-commercial services base-style: ways # all highway=* base-style: pipes-cables This is a rough idea, and it may change as I go. I will post a patch once it is complete (hopefully during this weekend), and gather feedback then. Hopefully there will not be too many issues with the evaluation order. I plan to add the "continue" action to the boundary lines, so that rivers or ways that are additionally tagged as boundaries will show up in the map. Best regards, Marko
