The main purpose of this guide is to assist you in using geostatistical tools with your own data. The book assists you in obtaining the software and making the first steps, warn what might be the bottlenecks and what you should avoid doing, and provide the most crucial tricks'n'tips on how to build scripts and organize the data processing.
The guide consists of four chapters.
The first chapter is an introductory chapter to the practice of geostatistical mapping and gives an overview of the spatial prediction techniques.
The second chapter zooms into regression-kriging and its characteristics, advantages and limitations.
The third chapter is completely dedicated to installation and doing first steps in the software, and the last, fourth, chapter gives a step-by-step guide through analysis and generation of final layouts by using a digital soil mapping case study.

After reading the first chapter, you should understand what the geostatistical mapping is; after reading the second chapter, you should know how to select the right spatial prediction technique for your application; after reading the third chapter, you should be able to install all packages used in the handbook and be aware of their capabilities; and after reading the fourth chapter, you should know how to run geostatistical mapping, prepare final layouts and interpret the results of analysis for your own case study.
