The book discusses about the comparision between Cumulative Semivariogram technique and widely used Semivariogram modelling technique. In this book both the techniques are tested on Bouguer anomaly data. The value of bouguer anomaly is predicted using Ordinary Kriging method. This book is referred for the academicians who wishes to carry out geostatistical projects to predict the behaviour of not only bouguer anomaly but for any regionalized variable in space. The book also discusses about the software developed by us to carry out geostatistical modelling.
