Every time mapnik encounters a new way, it takes it at face value, and restarts the shield rendering and shield repeats along the length of the way. As Richard pointed out, the min_distance is 120px, so it starts rendering the first shield of the next way a minimum of 120 pixels away from another shield. Point is, to us it looks like one long way, and we would maybe assume that a single shield would suffice, but to mapnik, it's a collection of unique ways, each taken at face value. Increasing the min_distance would introduce more problems where 2 shielded highways are close to each other. Still, it's a nice idea, and would perhaps be possible either be preprocessing the data in additional ways, or by enhancements to mapnik itself. Needs someone to try, test and implement it. -- Lennard _______________________________________________ Talk-ca mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-ca
