Are the .osm.bz2 and .osm.pbf files identical to begin with? Today, Geofabrik offers files with quite different timestamps:

I can't speak for the equivalence of the geofabrik extracts, but for my recent test I downloaded the pbf and used osmosis to convert between the formats. You can use: osmosis --read-pbf foo.osm.pbf --write-xml foo.osm.gz osmosis --read-xml foo.osm.gz --write-pbf foo.osm.pbf I also do not doubt that the produced maps contain the same elements, its just that they are in a different order depending on the input file. Since my previous message I have discovered one reason why this might be so, but there is still more reasons to be found.
Is there a tool that converts .osm.bz2 and .osm.pbf to a canonical format? If there is, then you could compare the canonical formats to see if the files are truly equivalent.
