Introduction to Geostatistics | Course Notes
Using inverse distance, the unknown value can be evaluated as: z0 = Xn i=1 wizi (estimate) wi = 1=di Pn i=1(1=di) (weight) We can see that the above relation is a linear estimator, i.e., z0 is a weighted sum of the n known values. Each weight (wi) (assigned to a known zi) is determined by the distance of the known data point to the unknown data ...
