In this final paper, based on the available literature, the most commonly used methods for assessing the geoelectric properties of soil are systematized. The measurement methods and methods for interpreting the measurement results are briefly described. After which, using the EarthModel software package, the results of measuring the apparent soil resistivity during geoelectrical sounding are interpreted. The first chapter provides a brief introduction, listing the basic geoelectrical parameters of the soil. After which, the methods used for assessing the geoelectrical properties of the soil and the reason for their application are listed. The second chapter describes the geoelectrical sounding method, measuring using the Wenner and Schlumberger methods, and the method of measuring and determining the apparent resistivity from the measured data. The third chapter briefly describes the surface impedance method and the method of measuring the field and soil impedance. The fourth chapter refers to the wave propagation method, the method of calculating the surface impedance and its application in wells or underground. The fifth chapter describes the wave rotation method, measurement techniques, and wave rotation equations. The sixth chapter describes the probe impedance method, i.e. the basic methods for measuring the electrical properties of the soil, the method of determining the input admittance of a transmission line and the electrical parameters of the soil. After that, measurement techniques and applications in boreholes are explained. The seventh chapter describes the mutual impedance method, the basic antenna structures and the method of calculating the mutual impedance for a particular structure are given. After that, measurement techniques and methods in boreholes or underground are described. The eighth chapter describes transient electromagnetic methods and the method of calculating the soil conductivity and the pulse measurement method is described. The ninth chapter describes the time-domain reflectometry method, the method of execution, measurement techniques and the calculation of impedance and reflection coefficient. The tenth chapter describes resistance measurement in the laboratory, the method of execution and determination of the apparent soil resistance. The eleventh chapter describes the capacitance method, the method of execution and the procedure for determining the dielectric constant of the soil. The twelfth chapter provides the theoretical basis for interpreting the results of measuring the apparent resistance using the EarthModel software package, after which an example of interpreting the task in the EarthModel software package is given.
