KRIGE2D Procedure

The KRIGE2D procedure performs ordinary kriging in two dimensions. Both anisotropic and isotropic semivariogram models can be handled. Four semivariogram models are supported: the gaussian, exponential, spherical, and power models. A single nugget effect is also supported. The locations of kriging estimates can be specified in a GRID statement or read from a SAS data set. The grid specification is most suitable for a regular grid; the data set specification can handle any irregular pattern of points. PROC KRIGE2D writes the kriging estimates and associated standard errors to an output data set.
