Дешифрирование многозональных аэрокосмических снимков: Методика и результаты

Summary

This atlas presents a systematic account of the interpretation methods and practical applications of multispectral aerial and space photography in Earth sciences, thematic mapping, resource surveys, territorial planning, and environmental protection. Its principal materials originated from the Soviet–East German “Raduga” experiment conducted within the Intercosmos program, together with imagery obtained by the MKF-6 multispectral camera from Soyuz 22, airborne laboratories, and the Salyut 6 orbital station. The MSP-4 multispectral synthesizing projector enabled the production of high-quality color-composite images for scientific, operational, and educational use. By juxtaposing photographs, interpretation schemes, and thematic maps, the atlas evaluates the selection of optimal spectral bands, comparison of band series, analysis of spectral signatures, and construction of color composites. It describes a graduated methodological framework ranging from visual interpretation and instrument-assisted measurement to digital processing, automated classification, and high-frequency filtering. Regional case studies encompass the shallow northeastern Caspian Sea, the southern and northern Baikal regions, Central Yakutia, the southwestern coast of the Sea of Okhotsk, southeastern Kazakhstan, the Fergana Valley and Pamir–Alay ranges of Central Asia, and northern and central areas of the German Democratic Republic. The investigated themes include geological structure, tectonics, geomorphology, glaciation, permafrost, river sediment transport, coastal processes, bottom deposits, submerged vegetation and landscapes, soils, terrestrial vegetation, agricultural crops, land use, settlement patterns, and anthropogenic landscape transformation. The studies demonstrate that natural and human-made objects can be distinguished through differences in spectral tone, color, texture, shape, size, spatial pattern, and contextual association. Interpretation reliability increases when multispectral imagery is combined with field observations, reference profiles, density standards, and, where available, multitemporal information; results may then be extrapolated to territories with comparable environmental and land-use conditions. The detailed example of Lake Süsser See shows that multispectral photographs can discriminate arable fields and individual crops, orchards of different ages, meadows, settlements, agricultural buildings, roads, recreational facilities, abandoned land, wetlands, reed beds, and water bodies. They also reveal cultivation practices, harvesting and reseeding, former crop patterns, soil moisture contrasts, erosion, groundwater-related subsidence, and unused areas. The resulting maps document land-use conditions at the time of acquisition, permit inventories of utilized and unutilized land, and support agricultural management, transport planning, recreation development, water-quality protection, erosion control, and conservation zoning. Overall, the atlas concludes that multispectral aerospace photography is a timely, integrative, and transferable source of information for monitoring environmental change, renewing and rationally managing natural resources, protecting ecosystems, and guiding regional development.
