I think that cutting holes will not be necessary. Rules inside the renderer would be a much better way to do this - if area A is completely inside area B, then render the area as area A, or more general, if something is a part of two areas, render it as the smallest. Unfortunately it seems the actual renderers seem to have taken a different route, where in some cases the overlapping area gets a kind of mixed colour, and in other cases some type of area always takes precedence over another, even if it is a part of it, but I still think that a rule as specified above would be the best way to go. -- André Engels, [email protected] _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
