In the moment, this is just an idea, and I am thinking about the best way to do something like this. So I am not (yet) dependent on any special renderer. (The cutting would not be a problem at all, using e.g. osmosis, as gary has written.) Usually, I am using PostGIS/mapnik. So in principle, SVG would be an option as output (although I have not yet tried that for anything but very simple styles). It would of course depend on whether the transformations are manageable. But as far as I remember, the text is rendered as single letters by mapnik, so in reality that probably is no option. -- Holger Schoener [email protected] _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
