25 1) Indicate whether each of the following statements is true (T) or false (F). TF Range is discontinuity at the origin of the variogram TF Variogram is a variance of difference between z(x) and z(x+h) TP Nugget effect is spatial correlation between distant samples F Sill is a maximum correlated distance between sample values. 20 F Spatial variation is the variation of the difference between sample values with distance. 25 2) The variogram model of the regionalized variable is spherical with parameters Co-5, C=10 and a=200m. Calculate the values of the variogram at distances of Om, 100m and 300m. 2 lokasyon tenorian beri olm bcelys 25 3) What is the variance of error incurred when the unknown value of a sample at but of location x is estimated from the measured value of another sample at location x+h? kesti Assume any variogram model. 62 = 28(DE,DI) -F (DE, DE) FIDI,DI) PI=Xth 2=Vor [2(X)-2(x+h)], 25 erfor 25 4) What is the variance of the error incurred when the mean value of a segment AB of length 12m is estimated by a sample at its center if variogram model is linear?
