[STATSGRASS] Grass link to Gstat

[Agustin Lobo]

Great! thanks. I've downloaded http://gstat.geog.uu.nl/bin/gstat-2.4.2.tar.gz
and configured with:

./configure --with-grass --with-netcdf=/usr/local/netcdf-3.5.0 
--without-gdal

then make;make install;make install -n

And now it works with raster layers. I've tested
with an small one (50 x 100), now I'm testing a large
one (1000 x 1000).

Is it possible to save the variogram from
within  gstat -i and not just displaying it?

Agus
