Predictive maps of geoelectric sections (GES) of North and South America are constructed. The GES maps are capable of increasing the accuracy of electromagnetic field calculations in the VLF−LF−MF ranges of radio waves by 1.5-3 times as compared to the Morgan-Maxwell map. The studies of electrical properties of layered media by combined radio and geophysical methods in a variety of natural and geological conditions, and the proposed method of GES mapping have resulted in the construction of a new generation of maps showing the electrical properties of the underlying medium that account for the layered structure of the crust and have no analogues in the world. Predictive geoelectric mapping of all the continents of the globe is completed.
