[OSM-dev] Osmosis: Bounding polygon does not support change data as input?

[Andreas Kalsch]

I have set up a OSM database with Germany data. Now I want to update my 
data daily. I have not found diff files for Germany so I want to use the 
global diff files, which are not too big.
To re-import German data every day would be too expensive - it already 
took some hours.

In Osmosis, I tried this:

osmosis/bin/osmosis --read-xml-change data/osm/20080916-20080917.osc 
--bounding-polygon data/germany2pts.txt --apply-change --write-mysql 
host=localhost database=osm_de user=user password=xxx

Result:

So am I right thinking, that the bounding polygon filter does not 
support the input of change data?
