The shortcomings of existing methods for calculating the ground wave field strength are determining the relevance of the study. Despite the detailed theoretical study in this area, known software implementations of the techniques do not allow taking into account an arbitrary number of sections with specified characteristics of underlying surface on a ground wave propagation path. The aim of the research is to generalize wellknown theoretical studies on predicting the ground wave field strength and to develop an applied automated technique that allows calculations on the routes with an arbitrary number of homogeneous sections with data input from corresponding digital maps. This technique is implemented in the form of a script and a set of auxiliary functions in MatLab environment. The example of calculations for a path consisting of six segments is presented
