A refiew of the literature on the nature of boundaries (political, social, and physical) and difficulties in their definition precedes a proposal for the use of remotely sensed and cartometric measurements for the more objective solution of boundary problems. A cartographic-morphometric method for the analysis of boundaries is outlined.

Abstract

It is doubtless true that the cadastral surveys of the British Empire are controlled more frequently by traversing than otherwise. Accordingly, although the traverse has been the subject of several papers in recent issues of this Quarterly, its widespread use appears to entitle it to every consideration, especially since there are elements in the completed procedure on which opinions are still fluid; indeed a few of them may long continue to arouse debate.  相似文献

The author outlines a structured approach to the use of maps in monitoring environmental change and natural hazards. Four levels of mapping are identified, corresponding to the activities of initial information gathering, preliminary forecasting, operational forecasting and control, and impact assessment. Cartographic monitoring of forest fires provides an example of the procedure. Translated from: Vestnik Moskovskogo Universiteta, geografiya, 1982, No. 6, pp. 79-84.  相似文献

A review of basic theoretical principles of “ecological” mapping and types of maps of the environment sets the stage for a more detailed treatment of ecological-geographic maps—maps portraying a wide range of nature-society and nature-nature relationships—as they are used in support of economic development and environmental monitoring in Siberia. Particular attention is devoted to the compilation of map series, which include ecological-geographical maps, for the Lake Baykal area, BAM service zone, West Siberia, and specific territorial production complexes (e.g., Kansk-Achinsk TPC).

A Russian geographer summarizes the results of a comprehensive study of modern landscapes and the mapping of diverse ecological situations. The procedure involves the development of a system of criteria and indices for the assessment of the properties of the environment, which provide a sound basis for comprehensive ecological mapping. The importance of an ecological assessment in the mapping of environmental problems and situations in support of the stable and balanced development of regions is demonstrated.

Another paper in a series of articles on ecological-geographic mapping (see for example, Mapping Sciences and Remote Sensing, Vol. 31, No. 3, July-September 1994, pp. 185-220) focuses on outlining a concise typology of such maps and providing a brief history of their emergence during the 1970s and 1980s. A subsequent section is devoted to methods and technology used in the compilation of ecological-geographic maps, particularly the multiple variants of data organization, processing, and cartographic representation that can be factored into research design.

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. Translated from: Geodeziya i kartografiya, 1984, No. 12, pp. 28-31.  相似文献
