[SOLVED] Plot a variogram model and it variogram map

[markm0705]

I'm looking for examples of
A) How to plot a 3D variogram model along with its anisotropy axis directions (or any desired direction for that matter) along with the model parameters on the plot
B) Is it possible to present a 3D model as a variogram map so I can check visually the rotation angles entered in the model are as expected.

If you could point me towards any existing examples that would be much appreciated.

Dear Mark
You will find in the documentation section :
- a vignette about 3D variograms: http://rgeostats.free.fr/doc/Vario_3D.html
- an example script for 2D variogram map calculation when data are organized as a 2D grid : http://rgeostats.free.fr/doc/Examples/Vmap.Rmd (vmap.grid)
- a course on how to build a variogram map when data are organized as isolated 2D points : http://rgeostats.free.fr/doc/Courses/04_Variography.Rmd (vmap.calc)
Please note that before calculating a variogram map, you will have to transform your input database in 2D (removing third dimension)

Hope this helps
