Kiriging interpolation
WebOrdinary kriging. Kriging utilizes the theoretical variogram to interpolate values at any location based on distant-variance relationship. We’ll perform Ordinary Kriging at the meuse grid locations. Recall, ordinary kriging has a constant intercept, denoted in the … WebKriging. Tools for performing the Kriging interpolation of a function f:R->R. We use a quadratic regression to fit the sample points, and a Gaussian function for defining the covariance.
