Explain how the Kriging interpolator estimates the semi variance between the unknown point and a known point without knowing the value at the unknown point. If you are asked to interpolate the value at an unknown point from 10 known sampling points using ordinary kriging, how many simultaneous equations do you need to solve? za to solv the estimated weights? What are the major differences between IDW and Kriging? In what way are they different regarding 23/1 Wen L 861fere
