<p class="MsoNormal"><span

Micha Silver and Helmut Kudrnovsky, the problem ist solved.
I did not set g.region prior to using v.what.rast. Seems to
be a typical non-Grass-Professional mistake. Now it works
fine.<o:p></o:p></span></p>

<p class="MsoNormal"><span
style="font-family:"Verdana",sans-serif">But to be
honest, I do not really understand what it is good for. When
the raster image and the points to be updated share the same
Grass location and CRS, why do I have to set a region in
addition?<o:p></o:p></span></p>
