[GRASS-user] Fill area between isolines?

hello Marcus and others,
just wanna give feedback and say thanks:

This procedure works well.

The most important step 
(as nearly everytime working with GRASS)
was the g.region settings.

I always have problems knowing my exact resolution
 for the target region "res=1 -a YY".

But using a raster map with similar extend and under the same mapset worked well.

Thanks for your hint. A feature this command seems to me very hidden, though.
