If you did not use osm2pgsql for part of the import then you don't have the data loaded in the correct way. Osmosis can load the OSM data into postgres but not in the correct format for Mapnik to use.

The mod_tile code lays out the tiles assuming the "900913" projection as used by the OSM tiles: http://wiki.openstreetmap.org/wiki/Slippy_map_tilenames If you change to a different projection then things will probably break. > > > > > Does anybody already fixed issues like that? > > > > > > > > > Regards, Michael > > > > > > > > > _______________________________________________ > > > 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 _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
