WebThe basic idea of kriging is to predict the value at a given point by computing a weighted average of the known values of the function in the neighborhood of the point. Unlike other deterministic interpolation methods such as inverse distance weighted (IDW) and Spline, kriging is based on auto-correlation-that is, the statistical relationships among the …
