This paper outlines some principles believed necessary for the establishment of integrated collections of remote sensing imagery, including, at the national level, a unified state image repository for the USSR. A multi-criterion classification of imagery is introduced, which provides a framework for structuring such a repository, and a number of measures for evaluating the utility of imagery within it are described. One of the latter is “geographic” resolution (levels of image detail), which provides a relatively straightforward indication of the type of geographic information embedded within particular types of remote sensing imagery.

The authors describe the principles and method used in compiling a map of game animal resources for the Midlands region, the name given to the middle segment of the Soviet Union comprising West Siberia, Kazakhstan and Central Asia. The results make it possible to recommend the optimal use of game resources and to identify future prospects of the trapping and hunting economy.

A second paper on floodplain and channel mapping describes how the “cartographic method” (the use of maps to derive information about the world not readily available through other means of investigation) is applied through the use of special maps depicting the sizes and types of river channels, the character of floodplains and of channel deformation, and the general conditions responsible for channel evolution. The uses, strengths, and limitations of channel maps at small, intermediate, and large scales are discussed, as well as methods of cartographic presentation that have proven most effective.

A Russian geographer describes a methodology whereby data on slopes contained within a geographic information system are employed in the compilation of geomorphological maps. More specifically, the author proposes and tests a technology for the automated compilation of electronic maps of mean slope for the territory of Altay Kray, West Siberia, Russia.

A Siberian geographer outlines the major aspects of a program to map the climatic and ecological state of ecosystems in the Lake Baykal region of southern East Siberia. A methodology for the classification of micro- and mesoclimates is outlined that is based on the structural characteristics of the underlying terrain surface, the character of air flows into the region, and extensive study of natural conditions in the region.

The activities of the Pacific Institute of Geography, USSR Academy of Sciences in the creation of a series of standardized computer (line printer) atlases of sown areas and yields of basic agricultural crops at 1:8,000,000 scale are described. Contributions by Institute researchers in the development or refinement of greytone scales for alphanumeric areal symbols, computer mapping programs in general, and applications of line-printer maps in planning and nature management are also mentioned.

General issues in the organization of geographic information systems are examined, with some examples pertaining to GIS in agricultural planning and production management. Two initial sections explore both theoretical and practical challenges involved in the development of GIS in the Soviet Union. Then the specifications of a suitable GIS in agriculture are outlined based on principles elaborated earlier, with specific proposals on how to overcome the numerous significant difficulties involved in its implementation.

Methods of assessing the informational content of multispectral imagery from satellites are examined. The utility of integral measures of the quantity of information from selected vis-à-vis one- and two-dimensional histograms of the brightnesses of multispectral space images are demonstrated. Such a procedure makes it possible to compare data obtained at different times and data obtained using different measuring instruments, which facilitates solution of the problem of predicting possible changes in the investigated area under the influence of natural and human agents.  相似文献

A survey of the use of topologic concepts of space in map transofrmation supports the author's contention that so-called “transformed images” represent for the most part rather arbitrary distortions of conventional maps constructed in Euclidean space. This paper demonstrates how truly topologic images can be created “from scratch,” i.e., without manipulation of either the sizes or shapes of areal units on preexisting maps. Images created by quantitatively defining “graphic ratios” of areal units can thus be replicated by other cartographers with a minimum of subjectivity.

The authors describe the results of a long-term program for the testing and refinement of a geology-geomorphology block in an instructional GIS at a scientific field station administered by Moscow University. Particular attention is devoted to the formulation of a series of practical exercises designed to familiarize students with the capabilities and limitations of GIS in the solution of practical geological and geomorphological problems.

The authors outline the general policy governing the use of remote sensing in Siberian mineral exploration—as a tool in the structural-geomorphologic mapping of potential mineral-bearing locations. Such maps are used to infer geologic structure (and endogenous conditions for mineral formation) and the character of contemporary exogenous processes (and conditions of transport and concentration of mineral residues) from geoindicators in surface terrain visible from space. Uses of space imagery in the study of seismic activity and engineering geomorphology are also described. Translated from: Kompleksnyye aerokosmicheskiye Issledovaniya Sibiri, A. L. Yanshin and L. K.

The authors present the results of experiments in the use of remote sensing imagery for construction of maps depicting human modification of nature. Four diverse areas within the USSR were selected as mapping sites, providing a broad range of environmental and land-use characteristics for investigation. Human impacts were most effectively mapped for two desert sites. The authors recommend combining satellite imagery with terrestrial spectrometric observations or color-infrared photography in investigations of environmental change in steppeland and forested territory.

A paper presented at a symposium on “Communication and Society” (Inter-university Center for Postgraduate Studies, University of Dubrovnik, May 13-24, 1985) explores means for extending the use and effectiveness of maps in everyday life. Primary emphasis is on improving overall cartographic communication and devising more effective methods for using maps to augment other communications media, especially newspapers and television. Submitted by the author to the Editor-in-Chief for publication.  相似文献
