Dear Yadollah Well, there are many nice books (e.g. Geostatistics for natural resources evaluation), also the work done in the project Intamap is hihgly interesting. Anyway, one problem of anisotropy is that a coefficient of anisotropy is defined only in case of geometric anisotropy (same sill, different reange). So, if you use variogram as surface texture descriptor, as in my case, you need to define an index of anisotropy able to work also in condition of zonal and mixed anisotropy....or at least this was my solution.Hope that this is useful,SincerelySebastiano Trevisani

I want to work in the area of "Anisotropic variogram or covariogram models". I need to new refrences. Please give me (or address) refrence for anisotropy.
