A method is proposed for analyzing properties of solar radiation at the earth's surface based on satellite observations of cloud cover. It is shown that the amount of incident solar radiation is clearly governed by type of weather conditions and, more specifically, by the quantity and types of clouds. This affords a basis for predicting solar radiation receipt at the earth's surface.

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.

在简述遥感图像的几何畸变特征的基础上,本文着重讨论了包括陆地卫星多光谱扫描图像 (Lanasat-MSS)、陆地卫星专题制图仪图像(Landesat-TM)和航空多光谱扫描图像在内的各类 全景扫描图像(panoramic scanner image)系统几何畴变的成因、大小及其变化规律,提出了定 量计算图像上任一像元处系统几何畴变量D的计算公式。 本文探讨了全景扫描图像系统几何校正的基本原则,并根据这些基本原则,用Fortran语言编 制了可直接用于校正各类全景扫描图像系统几何畸变的实用程序。 用该程序对德国南部某地的航空多光谱扫描图像实施系统几何校正的结果表明,偏离航线不 同距离各部位影像的系统几何畸变均得到合理校正,图像上由于全景扫描造成的不程度的压缩现 象均得到相应的补偿。 相似文献

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. 相似文献

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.

Feature classification maps derived from visual and automated methods of interpreting band-specific and composite imagery from the “Fragment” multispectral scanning system are compared in the study of vegetation and related features along the Gulf of Riga. The automated method, featuring a two-stage unsupervised/supervised classification algorithm developed at Moscow University (see MSRS, 1984, No. 3, pp. 255-261) provided for enhanced discrimination of wetland areas, farm land, and settlements, as well as for the elimination of extraneous components (especially the above) visually classified as deciduous forest.

A method for determining areas of most intensive melting within a mountain snowpack is described, based on an inverse relationship between reflectance and age of snow at wavelengths greater than 0.8 μm. Comparisons between the area of snow cover detected on visible and near infrared satellite imagery at different times during the spring thaw, and more specifically differences in position of the snowline, permit identification of the upper boundary of a zone of intensive snow-melt and water discharge from the snow cover.

On the basis of data recorded by a thermal infrared multispectral scanner (TIMS) carried on board an aircraft laboratory, maps of volcanic regions in Russia were compiled on which portions of lava dating to different periods were identified. SIR-C (Shuttle) data, processed by computer, made it possible to obtain distinct boundaries of lava flows with cross-polarization. A three-dimensional digital model of the Northern Fissure of the Great Tolbachik Fissure Eruption, on which TIMS, Zeiss, and SIR-C data were plotted, was constructed. A lineament analysis was made it possible to genetically classify cinder cones on the eastern slope of the Klyuchevskoy volcano, and a zone of areal volcanism was defined. 相似文献

Algorithms, designed for digital image processing in standard mainframe computers and representing sequential stages in a land-use classification procedure, are used to produce maps of agricultural crop types from multispectral satellite imagery. Pixel reflectance values are first grouped according to an unsupervised “rapid classification algorithm,” or data compression procedure. Mean reflectance values of the resulting classes then go into a supervised “sequential clustering algorithm” where classes are refined according to training value and other parameter inputs. The objective is to increase the accessibility of automated image interpretation while balancing classification accuracy and processing time.

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.

General principles are outlined for the use of a series of remote sensing images (obtained for the same area of the earth's surface for different points in time) in the detection of significant changes in land use and environmental conditions. Emphasis is placed on visual methods of interpretation, and a number of different methods for graphically analyzing the dynamics of earth surface features on photographic image products are described. A final section describes procedures for cartographically representing the dynamics of features interpreted from multitemporal images.
