Abstract
The work was conducted within the framework of creation of a fundamental geographical work, namely: the Atlas of Territorial Development of the Regions of North and Northeast Asia. The study, carried out at a scale of 1:8,000,000, covers the territory located in the sector of the Arctic Ocean drainage basin, extending from the world watershed, located in the center of Mongolia, to the oceanic subarctic of the Russian Federation. The aim of the research was to study and map landscapes to address complex problems of spatial development of the macroregion. The process of map creation associated with classification constructions and geoecological interpretations was carried out within the framework of the geosystem concept of Academician V.B. Sochava. The principles of mapping are formulated, the organization and structure of maps, the forms and content of cartographic information, indicator features and criteria for assessing the state of geosystems in the field of security, and the system of methods and techniques used for the integration approach are defined. Based on previously published larger-scale landscape maps, a unified basic information cartographic framework for producing derivative conjugated maps of geosystems of various content has been created using geoinformation methods and MapInfo Professional GIS software. An idea has been formed about the stability of geosystems of regional rank as an important environmental factor stimulating or constraining the territorial development of the region. The main groups of classification features-indicators and criteria for assessing the stability of geosystems to anthropogenic impacts have been identified. The possibility of creating legends for estimated-predictive, predictive-advisory overview landscape maps and maps of multifunctional geoecological zoning of the territory using various combinations of classification geosystem features is considered. Within the unified atlas system, specially structured geographical information from the landscape map block will serve as a knowledge base on the natural environment, meeting the needs of complex problems of territorial development of the macroregion.
