PROBLEMS AND PROSPECTS OF THE COMPLEX ECOLOGICAL-GEOGRAPHIC MAPPING OF SIBERIA

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).

AUTOMATED MAPPING FROM THEMATIC INTERPRETATION OF SCANNER IMAGERY

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.     

THEMATIC RELIEF MAPPING BY COMPUTER

The authors describe a series of programs designed for the automated production of thematic relief maps. More specifically, a digital terrain model of a test site in northeastern Hungary provided raw data used in interactive processing and plotting of maps on relief (energy), slope angle, slope exposure or orientation, and tectonic structure lines. Applications in soil conservation, agroclimatology, and forestry are described briefly. Paper presented at the Euro-Carto III Seminar sponsored by the International Cartographic Association at Graz, Austria, October 23-25, 1984 and submitted to the Editor-in-Chief for publication.

THE CURRENT STATUS OF BATHYMETRIC MAPPING

A review article on world bathymetric mapping activity over the last quarter century from a Soviet perspective provides information about Soviet mapping programs of the deep sea and continental shelf. In addition, it addresses a number of methodological issues in bathymetric mapping which are attributed to the lag between advances in practical mapping activity and the development of cartographic theory—the selection of isobath intervals and appropriate scales for different sea floor features and intended map uses, and the proper use of layer tinting and other graphic techniques to depict variations in water depth without obscuring details of submarine topography.

EXPERIENCE IN MULTICOLOR THEMATIC MAPPING BY COMPUTER

The structure and operation of an automated hardware-software complex, in use in the Far East Division of the USSR Academy of Sciences (Vladivostok) to generate multicolor thematic maps for planning purposes, is described. Particularly noteworthy are adjustments, in the form of special interfaces, necessitated by the incompatibility of standard Soviet mainframe computers with the kinds of input-output devices commonly used in the West—notably the color display and graphics systems used to produce the final maps. Both preexisting maps and remote sensing imagery served, after digitization, as source materials. Translated from: Geografiya i prirodnyye resursy, 1986, No. 3, pp. 122-125.     

专题制图中多因素数据的Fuxxy-Grey局势决策综合分类

专题制图中，所收集到的数据经常是单因素的，而在专题地图上却往往需要把多个单因素专题数据进行综合分类来表示。本文中，采用Fuzzy-Grey局势决策（下简称F-G决策）来研究多因素专题数据的综合分类问题，把“数据的模糊性”引入到灰色局势决策之中，根据不同情况，讨论各局势上效果测度中模糊隶属度确定的建模方法，在合适的隶属函数的基础上，在计算机上对实例分类进行程序运行，获得满意的结果。研究表明应用该方法在专题制图中对多因素数据进行综合分类是一种有效的手段。     

苏州运河水质的TM分析

本文利用苏州地区陆地卫星TM数据和同期的地面水质监测资料建立了TM图像遥感水质模型,并将该模型应用于TM可见光彩色合成图像的分割处理,得到苏州地区水质空间分布图像。结合苏州运河水网的水文及水污染特征对遥感水质空间分布图像作了分析。结果表明TM数据真实地反映了苏州地区水质的空间分布规律,并得到当地环境监测部门的验证。     

遥感和生长模型相结合的小麦长势监测研究现状与展望

 遥感影像的信息波段及其组合可以反映农作物生长的空间信息，可对小麦进行长势监测和产量估算，具有及时性和广域性。生长模型是集气候、土壤、品种和栽培措施等因素为一体的，对作物的物候发育、光合生产、器官建成、同化物积累与分配以及产量与品质形成等生理过程及其与环境和技术因子关系综合量化的动态数学模型，具有机理性和预测性。将二者结合用于长势监测不但具有理论研究价值，还具有广泛的应用前景。本文在简要概述小麦生长模型和长势遥感监测研究进展的基础上，总结了生长模型和遥感相结合的小麦长势监测应用的研究进展，并提出一些今后研究设想。     

THE FUTURE PROSPECTS OF DATA ACQUISITION BY PHOTOGRAPHIC AND OTHER AIRBORNE SYSTEMS FOR LARGE SCALE MAPPING

This paper was the first to be presented at the Thompson Symposium 1984 which had as its theme “The future of photogrammetry”. The paper considers only the acquisition of imagery for large scale mapping and similar purposes. It discusses the role of the standard metric aerial survey camera and makes some proposals for the wider use of smaller format cameras. It also reviews the position with regard to other possible sources of imagery such as vidicon and solid state cameras.     

CURRENT PROBLEMS IN OCEAN MAPPING

The author, in a review of papers presented at the First All-Union Conference on the Geography and Mapping of the Oceans, outlines the present status and current trends of marine cartography in the USSR. Issues warranting increased attention include development of a systems approach for the mapping of marine ecosystems; improvement of methods and principles for the mapping of coastal zones, bottom relief, and shelf topography; and accelerated production of economic/resource maps of the oceans. Work now underway on a comprehensive, multi-volume A tlas of the Oceans reflects a Soviet concern with these issues. Translated from: Geodeziya i kartografiya, 1984, No. 12, pp. 38-42.
