KRIGE2D Procedure


The KRIGE2D procedure performs ordinary kriging or spatial prediction for spatial point referenced data. The following are highlight's of the procedure's features:

  • enables you to specify the correlation model by naming the form and supplying the associated parameters, or by using the contents of an item store file that was previously created by PROC VARIOGRAM
  • enables you to specify the locations of kriging predictions in a GRID statement, or they can be read from a SAS data set
  • local kriging is supported through the specification of a radius around a grid point or the specification of the number of nearest neighbors to use in the kriging system
  • produces an output data set that contains the kriging predictions and associated standard errors for each grid
  • produces an output data set that contains the neighborhood information for each grid point when you perform local kriging
  • supports BY group processing, which enables you to obtain separate analyses on grouped observations
  • automatically creates graphs by using ODS Graphics
