v.surf.rst -> elevation (fwd)

Hi all,

I tried to interpolate a DEM from Vectorcontourlines by using the Modul
v.surf.rst. The resulting Elevtions in the DEM are wrong -- looks like a
shift, I think the "real Elevations" are in the Decimal Places. If I check
the DEM with nviz, it looks like the surface I suppose. But a Query for
the Elevation Values result in the same "wrong" Values.

The imput Vector Lines (ArcInfo Line Cover importet by v.in.arc) might be
ok. If the Vectorlines are converted to Raster by v.to.rast and the DEM is
generated by r.surf.contour or r.surf.idw2 the Elevation Values are ok.

Any Ideas?

Andreas
