Nearest Neighbor


Nearest neighbor and Natural Neighbor are the simplest interpolants available. In Nearest Neighbor, essentially each point of estimation (node) becomes equal in value to its nearest neighbor. It is not necessary to set up parameters with nearest neighbor. Simply select Nearest Neighbor from the combo box in the Geo tab of the Control Panel. SADA is now ready for you to press the Estimates or Risk mapping buttons on the main toolbar.


The result of a nearest neighbor interpolation is a jigsaw puzzle pattern. Nearest neighbor is typically not satisfactory for most applications but can provide rough estimates for quick analytical purposes.
