Zonal Kriging - Selecting Nearest Neighbors

Sharp:

Data points from across a sharp boundary will not be used in the grid cell calculation.

Gradational:

Data points from anywhere in either zone maybe used. The semivariogram model from the location being estimated will be applied to all points.

Fuzzy:

Data points can be used from either zone, but only from within the buffer region of the neighboring zone.
