This step is available when one of the following interviews is selected: Interpolate my data, Draw a probability map, Draw an area of concern map, Calculate cost versus cleanup, Draw a contoured risk map, Draw a contoured eco dose map, and sometimes Develop a sample design.

Select Interpolation methods from the Steps Window. The following information is displayed in the Parameters Window.


Select the appropriate interpolation method from the list. There are five interpolation methods in SADA: Nearest neighbor, Natural Neighbor, Inverse Distance, Ordinary Kriging, and Indicator Kriging.
