Hello,

I am trying to find out if there is a way to specify an input barrier line or input barrier polygon Feature Class when performing interpolation?  Specifically I am using the Empirical Bayesian Kriging 3d interpolation method and would like to specify a barrier to limit kriging.  Thanks.

Cheers,
Blair

Hi Blair,

A barrier in geostatistics usually means a line where the values of variables change instantly.  Fault lines, cliffs, and shorelines are common barriers.  Unfortunately, Empirical Bayesian Kriging 3D does not allow barriers of this kind; the model assumes that the values change gradually without any discontinuities.  Two interpolation methods, Kernel Interpolation With Barriers and Diffusion Interpolation With Barriers, allow barriers to be used, but they are both 2D interpolation methods.
