The kriging interpolation

Web24 Nov 2024 · Kriging algorithm is a regression algorithm for spatial modelling and prediction (interpolation) of random processes or random fields based on covariance function. In specific random processes such as inherently stationary ones, Kriging algorithm can provide optimal linear unbiased estimates. Web13 Dec 2024 · The crucial step before kriging is to make a good choice for the probabilistic model, because the whole kriging interpolation relies on it. Remember the two characteristics of Gaussian processes: randomness and spatial correlation. Signal randomness is something that you cannot capture by nature.
