MAPPING THE SOILS OF THE MAJOR NATURAL ZONES OF THE USSR FROM REMOTE SENSING IMAGERY

The authors describe the results of their experience in the use of remote sensing imagery to map the distribution of soils within the major natural zones (e.g., wooded steppe, taiga, semidesert) of the USSR. Considerable attention is devoted to instrumental-visual methods of interpretation before the focus shifts to automated interpretation and methods of map compilation, particularly general mapping at intermediate and large scales. One section assesses the relative sizes of mesorelief forms and fields in various natural zones in an effort to determine at what image scales the soil types indicated by these features will be identifiable.

THE CONCEPT OF AN INTEGRATED REPOSITORY OF SPACE IMAGERY AND NEW CRITERIA FOR ITS GEOGRAPHIC AND CARTOGRAPHIC ANALYSIS

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.

NATURAL ZONES OF THE USSR ON SPACE IMAGERY: A NEW INSTRUCTIONAL AID IN THE SECONDARY SCHOOLS

The development of a new instructional aid in geography in the USSR is described–an exhibit featuring wall-map sized space imagery of major natural regions. Each station in the exhibit (prepared jointly by the Moscow University Laboratory of Remote Sensing Methods and the Main Administration of Geodesy and Cartography) includes a color image of a site representing one of seven major natural zones, a series of thematic maps based on results of image interpretation, a map showing the location of the imaged area within the USSR, and a series of ground photographs of typical landscapes and land uses.

THE CENTROGRAPHIC METHOD OF STUDYING SPATIAL STRUCTURE

The authors focus on modern applications of the centrographic method of geographic research and mapping—both in terms of how centrography may aid in the cartographic representation of certain distributions and in terms of how cartographic devices (e.g., centrograms) may be used in the more effective identification of centers. A brief history of the method's development in Russia and the USSR is followed by examples of the use of centrograms in simultaneously comparing shifts (a) of distinct but related phenomena and (b) of the same phenomenon but at different scale levels. A variety of centrograms are presented and analyzed. Translated by Jay K.

CARTOGRAPHIC PERIODICALS OF EASTERN EUROPE AND THE SOVIET UNION

The Chair of the Moscow University Department of Cartography surveys the current cartographic periodicals of the USSR and Eastern Europe, with special emphasis on the USSR, Hungary, East Germany and Poland. The number and relative importance of each country's periodicals reflect general levels of economic and scientific development, although periodicals even from small countries with relatively unfamiliar languages of publication make significant contributions. The Soviet Referativnyi zhurnal, kartografiya supplies Russian-reading cartographers with information on hundreds of cartographic publications worldwide.

DEVELOPMENT OF QUANTITATIVE METHODS OF STUDYING THE EARTH FROM SPACE

The paper surveys the development of “space geography”–a field of knowledge applying the methods of remote sensing, the physical sciences, and mathematics in the solution of geographic problems. Early advances featured methodological improvements (use of quantitative methods in image processing), whereas future research must focus upon perfecting our knowledge of: (a) relationships underlying the use of these methods, i.e., between environmental parameters and reflectance values, (b) methods of effectively combining different types of imagery, and image products and field work, in research, and (c) appropriate quantitative indices for feature recognition. Examples of the operationalization of such concerns are demonstrated for land-use and soil mapping projects.

USEFUL EXPERIENCE IN THE CREATION OF COMPUTER ATLASES

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.

THE STUDY AND MAPPING OF HUMAN IMPACTS ON NATURE IN DIFFERENT REGIONS OF THE USSR USING SPACE IMAGERY

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.

STUDY OF THE MORPHOSTRUCTURES OF MOUNTAINOUS AREAS FROM SPACE IMAGERY

The authors review recent developments in the USSR in the use of remote sensing imagery in the analysis, at the world-regional and local levels, of major relief elements (and structural elements manifest in relief) typical of mountainous country. Keys to their interpretation at a variety of scales are described. Case studies and detailed interpretation of imagery in the Soviet Far East and Central Asia (large-scale) and the Caucasus (intermediate-scale) provide for the identification of all morphostructural elements possible through traditional analysis, and in the latter case, for the first direct detection of transverse (cross-cutting) faults. Translated from: Geomorfologiya, 1988, No. 1, pp. 16-29.     

USE OF SPACE IMAGERY IN THE STUDY OF MASS EXCHANGE IN GLACIER SYSTEMS

The author surveys the use of remote sensing imagery in the study of mass exchange in glaciers, i.e., glacier dynamics resulting from phase changes in the water which they contain. A program of research now underway at the Institute of Geography (USSR Academy of Sciences) in conjunction with the “Priroda” Remote Sensing Center (Moscow) focuses on improving methods of data collection and mapping of glacier dynamics from space imagery, and particularly on identifying natural glacioclimatic zones believed to represent specific mass exchange conditions or regimes. The boundary of glacier nourishment separating areas of accumulation and ablation represents a key glacioclimatic indicator of mass exchange on satellite imagery and aerial photography.

THE RELATION OF CARTOGRAPHY TO THE LAWS AND CLASSIFICATION OF SCIENCE

The chairman of Moscow University's Cartography Department addresses questions about cartography's place in the system of scientific knowledge, qualifications as a science, subject matter, and methods of analysis. Critiques of recent theoretical works both within and outside the USSR lay the groundwork for the author's view of cartography: a multifaceted, interdisciplinary field of knowledge using maps for the presentation and investigation of natural and socioeconomic phenomena. Although few if any strictly cartographic laws exist at present, map use methods are applied widely for the discovery and analysis of laws in other disciplines.

MAPPING THE STRUCTURE OF THE SOIL COVER OF THE TAIGA FROM REMOTE SENSING IMAGERY

An experiment is described in which multiscalar remote sensing imagery is sequentially employed in the detection of various rankings of soil types endemic to the taiga natural zone in the northern USSR. Relief features, vegetation associations, extent of surface water, and drainage patterns visible on imagery at scales from 1:12,000,000 to 1:5,000, also examined at low altitude and in the field at a series of test sites, served as indicators of various soil cover types. Considerable attention is given to an explanation of why these features can be considered valid indicators of taiga soil types as well as to the appearance of the indicators on band-specific (black-and-white) and color composite imagery.

AN EXPERIMENT IN THE COMPILATION AND USE OF A COMPLEX ENGINEERING-GLACIOLOGICAL MAP

A method for the compilation of 1:3,000,000-scale maps of natural nival-glacial phenomena is proposed for an area of the High Pamir Range in Soviet Central Asia. Such maps depict the distribution, frequency and intensity/magnitude, and potential impacts of such natural hazards as avalanches, mudslides, “dirty snow” avalanches (combined avalanches-mudslides in late spring), icings (naledy), and glacier pulsations, and are used in the planning of construction and the maintenance of roads and other transportation corridors during winter and spring. Hypothetical examples of the use of the maps are provided. Translated from: Materialy glyatsiologicheskikh issledovanly, USSR Geophysical Committee Publication No. 55.

INTERPRETATION OF ECOLOGICAL-SOIL CHARACTERISTICS OF WOODED STEPPE ZONE IN THE CENTRAL RUSSIAN UPLAND

The authors describe how remote sensing imagery can be employed in the identification of different types of chernozem soils in a predominantly agricultural zone (forest steppe), where natural vegetation (normally one of the best vegetation indicators) has been largely displaced by farm fields. A multi-stage methodology is outlined whereby small-scale imagery is used to delineate large regions of similar bioclimatic-geologic characteristics, from which areas of similar soil formation conditions are distinguished. Multispectral and multitemporal space imagery then is employed to detect less salient ecological-soil differences that can affect phototone and image texture.

THE WORLD ATLAS OF SNOW AND ICE RESOURCES

The World Atlas of Snow and Ice Resources, scheduled for publication in the late 1980s, is an extensive cartographic summary of current knowledge about snow and ice. Roughly 750 maps organized under 17 broad themes cover topics such as glacier morphology, temperature and precipitation conditions in glacier formation, avalanches, meltwater runoff, sea ice, and past glaciation. The organization of the project is described along with the contents of major thematic sections, and examples of the use of basic initial maps to validate information used in more complex derivative maps are provided.

ESTIMATION OF PRECIPITATION FROM CLOUD-COVER PHOTOGRAPHS OF THE METEOR SATELLITES IN THE NONCHERNOZEM REGION

The authors propose a technique for reconstructing precipitation sums for particular areas on the basis of satellite cloud photography. The method is illustrated with reference to six 5-degree squares in the Nonchernozem Region of the USSR for the month of July during the period 1971-80. Good agreement is found not only between the reconstructed precipitation sums and the actual precipitation during the study period, but also between the mean of the reconstructed July precipitation during the 10-year period and the actual long-term mean precipitation for that month.

AN INITIAL ATTEMPT AT INTERPRETING THE STRUCTURE OF MOUNTAINOUS AREAS IN THE WESTERN ANTARCTIC WITH SPACE IMAGERY

The second of two reports on the use of space imagery in the interpretation of Antarctica's geologic structure applies interpretation procedures described in an earlier article (see Mapping Sciences and Remote Sensing, 1985, No. 1) to produce a geologic map of a portion of the Antarctic Peninsula. Features identified on space imagery and depicted on the map include: a deep pericratonnal fault zone, a Mesozoic fold belt interrupted by a complex system of faults, and ring or annular structures of volcanic origin.

USE OF SPACE IMAGERY IN COMPILING ENVIRONMENTAL-PROTECTION MAPS (with reference to the Soligorsk potash-mining district)

The authors apply remote sensing data to the mapping of natural envionment with a focus on environmental protection. The technique is illustrated with particular reference to a largely swampy potash-mining deposit in Belorussia which is the largest potash producer of the USSR, accounting for 54% of its total output in 1983.
