Fragen der komplexen geographischen Karten und deren Entwicklung in der UdSSR

This article examines the significance, forms, historical development, and future prospects of complex geographical cartography, with particular emphasis on achievements in the Soviet Union. Maps are presented not merely as instruments for recording and visualizing spatial facts, but as indispensable means of scientific comparison, generalization, inference, and forecasting. Their importance increases when geographical research serves practical objectives such as economic planning, resource assessment, and regional development. The author distinguishes three principal approaches: individual complex maps combining selected interrelated phenomena; complex atlases assembling complementary thematic maps; and coordinated series of standardized special-purpose maps intended for comparative use. Individual complex maps—including topographic, economic, and agricultural land-evaluation maps—can effectively address defined tasks. Yet efforts to place numerous physical and socioeconomic phenomena on one sheet often produce overcrowded and poorly legible results because scale, map area, graphic vocabulary, and the need for generalization impose unavoidable limits. Complex atlases therefore offer broader possibilities for representing territories comprehensively. The article traces their emergence from eighteenth-century projects and nineteenth-century advances in geographical theory, specialist disciplines, statistical observation, and thematic mapping. It discusses major Russian, Soviet, and international examples, including physical, climatic, economic, regional, national, maritime, and world atlases. Before the socialist period, ambitious atlases were constrained by insufficient data, fragmented research, commercial priorities, and the high costs of production. In the USSR, centralized scientific institutions, state planning, systematic surveys, and the demand for integrated knowledge of natural resources and productive forces created more favorable conditions. Soviet cartography consequently produced industrial and regional atlases, the Great Soviet World Atlas, the Marine Atlas, the World Atlas, and coordinated million-scale maps of natural conditions. The author emphasizes that atlas quality depends not simply on the quantity of maps but on a coherent scientific program: reliable and comparable source material, rational thematic selection, appropriate scales and projections, consistent territorial bases, coordinated legends, common principles of generalization, and graphic methods suited to each phenomenon. Standardized series of soil, geobotanical, geological, and other maps are especially valuable because they preserve thematic clarity while permitting systematic comparison and investigation of relationships among natural components. The Soviet 1:1,000,000 map series is therefore interpreted as an important stage toward an integrated cartographic representation of nature. Building on the partially realized International Map of the World proposed in 1891, the article calls for renewed international cooperation on a broader series of world thematic maps. It recommends first testing programs and legends through experimental maps at scales of 1:5,000,000 or smaller and through national maps and atlases. Overall, complex cartography is portrayed as a collective scientific enterprise whose future lies less in overloading single maps than in coordinating atlases and standardized thematic series for analysis, planning, and global geographical synthesis.
