Hi
I've been trying to use Darrell's s.surf.krig, could someone email me
a data set and the input parameters (nugget range etc) so I can see
if I've got it working properly. I've tried using my own data but
I can't get it to work satisfactorially, I suspect I'm not using
correct parameters but I'd like to rule out a bug I may have
introduced while compiling it. BTW has anyone done a cokriger
for GRASS
With the risk of being accused of anti-grass behaviour: try to get hold
of the PCRaster stuff (MS-DOS, yes, I know) from Utrecht University,
which includes a kriging module with example data which looks fairly good to
me, although I'm not an expert.
It also does a visual display of the semi-variograms and shows the fit
to the various interpolation models. It should be able to do co-kriging as
well. Import/export of GRASS data is fairly easy through ASCII format.
Address: pcraster@frw.ruu.nl (if I recall well), they can tell you the
conditions of use.
