The official version: I cannot see any code adjusting the alignment
of the contour lines. For the area where I'm living, it looks
perfect even without.

But I have added now options for this.

python is part on every Linux distribution, with mono, I didn't manage
to recompile it with mono to apply some fixes. And phyghtmap only
needs a fraction of memory as Srtm2Oms needs. As result, I'm now
able to build SRTM maps for countrys where I always failed with
Srtm2Oms. And learning python was pretty easy for me.

Until now I haven't found any tool which has problems with the
generated 0.6 osm format. Does somebody know about a tool which
does verify the data for errros?
I think "fixing" phyghtmap should be pretty simple.
