3.2.5 Kriging
Kriging is an interpolation technique and woks in a similar manner as IDW but the difference is the weight parameter is calculated using statistical relations obtained from semi-variogram model. The semi-variogram uses an empirical equation given by
\(\lambda\)(H) =\(\frac{1}{\ 2N(h)}\sum_{i=1}^{N(h)}{{[f\left(r_{j}\right)-f\left(r_{j}+h\right)]}^{2}\ }\)
