Yes, Mapnik can do that but you'll need to get quite familiar with the OSM code to be able to tweak the tile size since it has knock on effects on the constants in various algorithms (e.g. mapping tile co-ords to lat/long etc). A good place to start learning about the OSM setup is http://wiki.openstreetmap.org/index.php/Slippy_map You'll need to read a few of the linked pages to get a good idea of how it all fits together. Feel free to ask more questions on the osm-dev list (or IRC). > Another possibility I was thinking of, is if someone/some company > already has Mapnik configured, would they offer as a service, > rendering out all the tiles for me given some sort of Mapnik > stylesheeet which defines how I'd like the tiles to look?

They already make 64x64 tiles similar to your description. http://maps.cloudmade.com/mobile > Thanks, > Mark > > _______________________________________________ > Mapnik-users mailing list > [email protected] > https://lists.berlios.de/mailman/listinfo/mapnik-users _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
