Small-scale soil maps and the scientific heritage of N.N. Rozov

The comparative analysis of small-scale maps of the USSR has revealed the characteristics of their contents, concepts, and ways of compilation and cartographic representation. The facies-zonal concept is reflected both in the map legends and the patterns of the mapping units. The differences between the maps reflect the time of their creation: the degree of knowledge on the soils, the contribution of the geographic forecast, and the objective of the maps and their scale. Especial importance in soil cartography and geographic education belongs to the map of 1954 compiled by Rozov. Forty years later, it was replaced by a map of similar purpose, scale, and mapped area. This map was compiled at the Faculty of Geography (Moscow State University), and it has inherited many features of its predecessor—the map of Rozov.
