You can't apply a bbox to a change file. Change files basically contain the IDs of changed objects and their current properties. Notably, they do not contain the old properties of the objects, so osmosis cannot tell in all cases whether an object should be considered to be in or out of the bbox. If you're using osm2pgsql, you just have to apply the full change files. You can syill use osm2pgsql's bbox, which will restrict the data in the rendering tables (but the tables for slim mode will gradually accumulate data from outside the bbox that will only go away if you do a dump and fresh reload from a planet extract). -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- One can measure the importance of a scientific work by the number of earlier publications rendered superfluous by it. -- David Hilbert ---- --- -- _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
