TL;DR: A third installment in a series of articles devoted to the compilation of transformed images focuses on computer-assisted numerical image transformations, with particular attention to algorithms developed by Tobler, Tikunov, and Pikin.
Abstract: A third installment in a series of articles devoted to the compilation of transformed images focuses on computer-assisted numerical image transformations. Particular attention is devoted to algorithms developed by Tobler, Tikunov, and Pikin; Tikunov; White and Griffin; Kadmon and Shlomi; Petrov, Serbenyuk, and Tikunov; and Dougenik et al. Advantages and shortcomings of each of these methods are compared and a new algorithm is unveiled that is designed to eliminate some of the extant deficiencies in image transformation.

TL;DR: The capabilities of the various space-based sensors are compared in terms of their suitability for planimetric and altimetric mapping and some major applications of the resultant imagery are described.
Abstract: A French researcher surveys progress in geographical research associated with the interrelated development of remote sensing, computer-assisted mapping, and geographic information systems. The capabilities of the various space-based sensors are compared in terms of their suitability for planimetric and altimetric mapping and some major applications of the resultant imagery are described. Future research challenges and trends are addressed.

TL;DR: A second paper from a monograph devoted to the compilation and uses of transformed cartographic images focuses on analog/manual methods of areal image transformation—of particular relevance in areas and situations in which access to large volumes of computer memory is problematic.
Abstract: A second paper from a monograph devoted to the compilation and uses of transformed cartographic images focuses on analog/manual methods of areal image transformation—of particular relevance in areas and situations in which access to large volumes of computer memory is problematic. As such, it addresses problems relating to the transformation of a second type of transformed image—in which the areas of cartographic features of interest (rather than their linear dimensions) are scaled according to a nonspatial metric.

TL;DR: A Russian specialist describes the system employed in that country to monitor damage caused by forest fires and to assess the rate and character of forest regeneration and habitat change in burned-over areas using air photos and satellite imagery.
Abstract: A Russian specialist describes the system employed in that country to monitor damage caused by forest fires and to assess the rate and character of forest regeneration and habitat change in burned-over areas using air photos and satellite imagery. Particular attention is devoted to the use of such imagery for different scales of monitoring of fire damage—local, regional (oblast, Kray), and national; to classification of natural complexes based on frequency of fires; to compilation of forest combustibility indices; and to the compilation of maps showing the susceptibility of different natural landscapes to fire.

TL;DR: The author examines the development of theoretical thought in cartography over the past 50 years and argues that there is a convergence of these concepts and that an integrated geoinformation concept is taking form in modern cartography.
Abstract: The author examines the development of theoretical thought in cartography over the past 50 years. The following principal concepts are compared: cognitive, communicative, cartology, metacartography, and map language. Their differences in the interpretation of the subject of cartography, the essence of a map, cartographic generalization, and the relationships between cartography and other sciences are indicated. The argument is advanced that there is a convergence of these concepts and that an integrated geoinformation concept is taking form in modern cartography.

TL;DR: In this paper, the authors used remote sensing-based research on the structure of frontal zones of the Pacific Ocean portion of the Antarctic Ocean and found that the origin of the difference between stepped and intermittent types of frontal structure is attributable to a different type of baroclinic-barotropic instability along these fronts.
Abstract: Results of remote sensing-based research on the structure of frontal zones of the Pacific Ocean portion of the Antarctic Ocean are discussed. The principal remote sensing technique employed is infrared radiometry. Satellite radiometric measurements of the sea surface temperature are compared with surface temperature measurements. The hypothesis is tested that the origin of the difference between stepped and intermittent types of frontal structure is attributable to the prevalence of a different type of baroclinic-barotropic instability along these fronts.
TL;DR: Specific transformed images used to illustrate the range of existing applications include those scaled according to population size, GNP, various illness rates, density of ocean vessels, oil pollution in the ocean, and fisheries and offshore oil and gas deposits.
Abstract: A final installment in a series of papers on transformed cartographic images in geogaphy (see Mapping Sciences and Remote Sensing, 1993, No. 4, pp. 306-319 and 1994, No. 1, pp. 33-85) focuses on their applications in more effectively depicting a variety of spatially distributed phenomena. Most applications are demonstrated using images compiled via a method developed by the authors. Specific transformed images used to illustrate the range of existing applications include those scaled according to population size, GNP, various illness rates, density of ocean vessels, oil pollution in the ocean, and fisheries and offshore oil and gas deposits.
