riging is a geostatistical process that estimates a surface from a scattering of z-valued points. Kriging is similar to IDW in that it uses measured values to estimate an unknown location.
Fitting a model is also called structural analysis or variography. empirical semivariogram, computed with the following equation for all pairs of locations separated by distance h:
Semivariogram(distanceh) = 0.5 * average((valuei – valuej)2)
The empirical semivariogram is a graph of the averaged semivariogram values on the y-axis and the distance (or lag) on the x-axis
