Excellent. I've done this at a really small scale as well, and even made up tagging for these nodes as well, including ref=*, operator=*, and various other pertinent bits of information for those markers, and connected the odd ones into a pipeline way. > problem is how to tag the direction of flow.

Don't worry that much about what mapnik shows. I would've used oneway=yes tagging as well, I think. Either that, or possibly flow=forward/backward. Mapnik currently renders oneway arrows for *every* way with the oneway=yes tag, and that could probably be limited to highway/railway/waterway=* without serious impact to the map. Speak up if you think this is a bad idea, else this change can go in soon. -- Lennard _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
