TL;DR: Torrey et al. as discussed by the authors presented a methodology for completing a digital terrain model of the Earth's surface using overlapping radar images from different orbits of the Almazl spacecraft, which demonstrated how orthographic and topographic images can be derived via the processing of two overlapping images.
Abstract: A methodology for completing a digital terrain model of the Earth's surface is described, which utilizes overlapping radar images from different orbits of the Almazl spacecraft. Algorithmic digital image processing procedures are described for compiling a three-dimensional image of surface terrain from two images forming a stereopair. Using imagery of North America's Great Basin desert that is roughly analogous to that of the Shuttle Imaging Radar-B of the U. S., the paper demonstrates how orthographic and topographic images can be derived via the processing of two overlapping images.

TL;DR: Torrey as discussed by the authors describes a procedure for the compilation of large-scale maps depicting changes in the character of exogenous processes (e.g., erosion by wind, rain, ice, etc.).
Abstract: The paper describes a procedure for the compilation of large-scale maps depicting changes in the character of exogenous processes (e.g., erosion by wind, rain, ice, etc.). It relies on such models as the Universal Erosion Equation to simulate such processes as sheet erosion. The types of features portrayed on the resulting map products are described, with the superimposition of an isarithmic map of the material balance (receipt and removal of matter at individual points by exogenous processes) onto a map of key exogenous processes yielding a map of the dynamics of recent exogenous processes.

TL;DR: In this article, a technology for processing AVHRR/NOAA multispectral data for supporting local oceanographic monitoring is described, and an algorithm is proposed for mapping the field of surface currents.
Abstract: A technology for processing AVHRR/NOAA multispectral data for supporting local oceanographic monitoring is described. An algorithm is proposed for mapping the field of surface currents. Accuracy in determination of sea surface temperatures is tested via comparison with in situ measurements in the coastal upwelling zone.

TL;DR: This paper discusses algorithms employed in their compilation, presents a new algorithm for this purpose, and demonstrates several applications of transformed images in geographical research by contrasting transformed images compiled according to traditional and new methods.
Abstract: This paper is devoted to the problem of compiling and using transformed images in geographic research. It discusses algorithms employed in their compilation, presents a new algorithm for this purpose, and demonstrates several applications of transformed images in geographical research (by contrasting transformed images compiled according to traditional and new methods).

TL;DR: Whether the association of the statistical characteristics of the spectral structure of visible radiation with meteorological parameters is strong enough to serve as part of the explanation for the onset of different states of atmospheric turbidity is tested.
Abstract: An analysis of the statistical characteristics of the optical depth of suspended particulates was made in several parts of the visible spectrum as it is affected by meteorological conditions. The paper tests whether the association of the statistical characteristics of the spectral structure of visible radiation with meteorological parameters is strong enough to serve as part of the explanation for the onset of different states of atmospheric turbidity. Equations are derived that permit estimation of atmospheric optical conditions from meteorological data.

TL;DR: Luchanskaya et al. as discussed by the authors described a project undertaken by Moscow University geographers to evaluate and map the natural gully erosion hazard for plains areas of European Russia, compiling a series of maps on specific natural characteristics with a bearing on gully formation.
Abstract: This paper describes a project undertaken by Moscow University geographers to evaluate and map the natural gully erosion hazard for plains areas of European Russia. Compilation of a series of maps on specific natural characteristics with a bearing on gully formation serves as the basis for the creation of a map depicting the natural susceptibility of areas to gully erosion used in forecasting the potential maximum density of the gully network.

TL;DR: In this article, the results of integrated landscape mapping at different levels and scales (global, regional, local) are presented, where the relationships between physical environment, land use practice, and degree of landscape modification were studied for various arid regions.
Abstract: The results of integrated landscape mapping at different levels and scales (global, regional, local) are presented. The relationships between physical environment, land use practice, and degree of landscape modification were studied for various arid regions. A hierarchical concept for the organization and mapping of land units, developed at Moscow University, is applied to particular land use mapping problems of arid lands, e.g., of environmental destruction in the Aral Sea region, monitoring landscape changes in Iran.

Abstract: The authors outline how a decentralized ground reception and processing network for satellite remote sensing data has the potential to provide information more efficiently and rapidly than Russia's existing network of a few large central facilities that are charged with supplying preprocessed data to the user community. The components and linkages in the proposed new network are described.

Abstract: The process of the automated compilation and plotting of thematic maps based on selected methods of cartographic representation is examined. The authors argue that the essence of logical and mathematical processing of digitized space imagery is formalized, objective cartographic representation of the results of image interpretation. General procedures of map compilation are operationalized based on a geomorphological mapping project using Landsat MSS data for the Moscow Region.

Abstract: This study uses space imagery, particularly false-color composites, to identify and map major natural complexes of the Yerevan basin and the changes they are undergoing as a result of a variety of in situ and “imported” pollution impacts. Interpretation aides in the identification of areas affected by different types of pollution in the basin are identified.
