WebbKNN (also stylized as kNN) is a neighbor-based learning method that can be used for interpolation. Unlike the Thiessen polygons method, KNN looks for a specified number K of sampled points closest to an unknown point. The K known points can be used to predict the value (discrete or continuous) of the unknown point. 3.
