AI-GEOSTATS: angular tolerance of variogram
- Hi there,
I�m looking at a soil samples taken as a12.5m grid (540*180m) of a very homogeneous field. I�m
using variowin and have been calculating variograms of soil properties in different directions. The
long side of the field lies approx in South/north direction (about 80 degrees), which also runs
parallel to the topographic gradient. Calculating the variograms in the direction of the slope (about
0 degrees) I get a spatial dependency up to where the slope starts (I�m fine with that).
If I now calculate the variograms in direction perpendicular to the slope (about 80 degrees) I only
get a well behaved variogram for exactly 90 degrees, 5 degrees more or less gives no spatial
dependency at all.
My question is if I get a well behaved variogram which is not tolerant to any angular change could it
be an artefact of some kind??
Any suggestion will be greatly appreciated
