Mapping of large urban agglomerations in the People Republic of China based on remote sensing data (using the example of Shenyang)

Urban forms of settlement now have a direct impact on all aspects of the economic, social and cultural development of society. The study of the growth dynamics of cities and megacities using photogrammetry methods, together with the display of the structure and relationships of the studied territories by the methods and techniques of geoinformation cartography, becomes part of the system of scientific study of urbanization processes as a whole. At the same time, both technical algorithms for processing space images and final cartographic models compiled on the base of geographic information systems (GIS), what allow automated methods to track changes in space and time in a particular territory, are studied. This article demonstrates the development of an algorithm for processing remote sensing data (RSD) for creating electronic maps for the territory of the People`s Republic of China
