I don't use osmosis but osmconvert, from a script by Paco Tyson which
includes french addresses (from BANO database).
But without I obtain the same result.
The scripts use "--precom-sea sea.zip" and "--bounds bounds.zip".
I will try with a .poly file including the whole lake.
Will report if it is OK, or not !
Thank you !
