[OSM-talk] z12 bounding box
Is there an easy way to figure out what the equivalent bounding box of a particular tile would be? For instance, I want to use osmosis to cut out a bounding box that contains all the info in a particular z12 tile (or any zoom). How would I figure out what the lon and lat values would be for the tile? I'm guessing it's possible since the [EMAIL PROTECTED] client does it when it requests data from the API, but I'm not clear on how it works. Thanks, Jeremy___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Actually the [EMAIL PROTECTED] client uses a bigger bbox than the tile itself, but there is a reasonably simple formula to get from x,y,zoom to lat/lon and vice versa. for perl there are the functions in tahproject.pm[1] Project and ProjectL [1] http://svn.openstreetmap.org/applications/rendering/tilesAtHome/tahproject.pm - -- Dirk-Lüder Deelkar Kreie Bremen - 53.0952°N 8.8652°E -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHj8enFUbODdpRVDwRAuB6AJ4jByb2zjuHYGppEV2CqWRPlbEEJwCfVRVV lHgNesYr8F239IBL+97TQYg= =id+P -END PGP SIGNATURE- ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Thanks to everyone for the great info. To clarify: Project and ProjectL together return the correct bbox for the tile, *not* the bigger bbox used by [EMAIL PROTECTED] - -- Dirk-Lüder Deelkar Kreie Bremen - 53.0952°N 8.8652°E -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHj/zlFUbODdpRVDwRAqZ2AKCY17x15cPJDecpVLt6vXurJNBlwgCdEHvD pMqOU09I0sZMOhC9bah9eQI= =DCku -END PGP SIGNATURE- ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
