It would make sense to output the geometry part of the data as GeoJSON, or even WebGL. What I've done for the wikipedia overlay at openstreetmap.pl/wp was generate the tiles of OSM data in GeoJSON instead of .png but otherwise similar to the bitmap tiles. What tiling gets you is browser caching of the data. Cheers _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
