[GRASSLIST:558] Re: PD: raster 3d from DEMs

[Marino Vetuschi Zuccolini]

Hi Maciej,
to define geological units (or in general a 1D/2D/3D categorical  
variable in the "space") you have to use algorithms able to compute  
them.
We generally use stochastic algorithms based on Gaussian Simulations as  
implemented in gslib and gstat or Uncert packages after a study  
concerning the variable spatial distribution.

I hope this helps
