Jan, you sent this to me personally not to the list - although you may have posted it earlier to the list and I din't see it.You lost the right to my response when you turned down my invitation 12 years ago. Your relentless attempts to denigrate a subject simply because you do not understand
Hi, I do not know whether you received any answers off-list, so here goes.The "spherical" model of geostatistics was so-named by Matheron and is sometimes also known as the Matheron model. His idea was that a sample has a 'sphere of influence' around it. Potential (or actual) samples within
Dear list
members,
Does anyone can help
me understanding variogram range interpretation or send me some specific
references.
I am currently
analyzing variograms computed over the same site of a remote sensing image. The
first variogram was derived from the original image and the second
Dear list membersMy question is about the practice of replications.As you know, in orderto avoid measurement/analysis errors, one may wish to replicatehis/her measurement at the same spatial point in the field or his/her analysis for the same sample in the laboratorymany times. For
First, the range of a variogram (if it actually has one) is the distance at
which the variogram value becomes constant with respect to lag distance (note
that a variogram with a geometric anisotropy will have a different range for
different directions. The constant value is the sill
Second,
Dear Isobel,
Thanks for your reply. It is the first reply regarding
this subject. Beforehand, I got one information
mentioned that spherical model corresponds to a Random
Function resulting of the summation of 3D spheres
random in space, each sphere being given a value.
Moreover, it is
