[50]2. The attribute values and coordinates of the 7 points (Points 1-7) in a region are shown in figure below. Predict the attribute value at the Point(0) by using ordinary kriging. Show all your computations. Hint: Use an exponential variogram model of y(h) = Co+C1[1 - exp(-3h/a)], where Co = 0, a = 10 and C1 = 10. 6 5 . ?(696) 1 (447) (791) (606) Coordinates Attribute Value Joo Distance from Point (0) Poin X Y t 1 61 139 477 4.5 4 2 63 140 696 3.6 .
