[OSM-dev] CloudMade OSM download problems

Great! That works.

Another osmosis question .. is there any way to merge two osm files? I now have an osm for Pakistan and California, and I want to load both. However there is a warning about duplicate key constraint violation .. somehow both Pakistan and California share a node.

Importing into an OSM instance is always problematic due to the foreign
key relationships.  They're a good idea in the central database, but
difficult to satisfy when working offline with extracts and changesets.

OPTION 1
If you're just trying to import a one off extract into the database you
can use osmosis to fix the referential integrity problems.
osmosis --rx myfile.osm.gz --bbox clipIncompleteEntities=true --wx
myfixedfile.osm.gz

That should modify ways to only refer to nodes that actually exist.  No
coordinates have been passed to the bbox task so it will select the
entire planet (or in this case, the entire input file).  Note that
modified ways will no longer match the main API ways exactly so they
should never be uploaded back to the main database.

OPTION 2
If you wish to apply changesets to your database to keep it up to date
you'll probably need to drop the problematic foreign key relationships.
