Hi all, reg. background polygon: I wonder how this is supposed to work. I see these possibilities: 1) Try to calculate a (multi)polygon using the admin_level=x ways and cut all lines and shapes exactly along the boundaries of the polygon 2) Like 1) but increase the size of the polygon by a given percentage (JOSM has such a function called "Make parallel copies of ways"). 3) Let the user specify a (multi)polygon and cut all lines and shapes exactly along the boundaries of the polygon. The user can decide if he wants overlaps or not. I see one big problem with 1) and 2) : What should happen when the boundaries don't form a polygon? I think we end up with the same problem as in the sea generator, therefore I think 3) is the way to go. Comments?

Maybe there is a reason to add another new processing algorithm in Mkgmap? How I see it: 1. The Splitter is doing its job as it is now. Without any changes. 2. Mkgmap takes a specific the boundary relation or admin_level from the data or a poly file for the final generation of the background polygon. This feature in Mkgmap is really lacking! I do not know how to do it because I am not a programmer. Just an idea.
