Hi Michal,

Did you contact the osmosis maintainers?
I can try to write a routine that sorts the data, but
I don't want to rewrite the osmosis code if not really
needed. I guess SRTM data uses negative ids
which are sorted, but in the "wrong" direction:
-1,-2,-3 instead of 1,2,3

A simple work around would be to use a
formula like
id = fixed_offset - id;
to get the order that is needed in splitter.
