USE OF REMOTE SENSING IMAGERY IN MULTIPURPOSE MAPPING

This paper focuses on remote sensing's role in support of diverse mapping tasks, including those of interest to soil scientists (land use, soil, and botanical mapping). It analyzes new opportunities and challenges provided by remote sensing imagery with respect to map compilation and revision: the interdisciplinary yet goal-oriented character of map themes, the large stock of data to be processed systematically for coherent information yield, the numerous linkages of map elements to be represented on a series of closely interrelated maps, and the need for standardization and a unified approach to map design and symbolization.

REMOTE SENSING IMAGERY AND ECOLOGICAL PROBLEMS OF COASTAL ZONES

Materials derived from aerial and space surveys provided the basis for compilation of a series of geomorphological, geological, morphostructural, and lithodynamic maps as well as a map showing sources of manmade pollution. A derivative map of geoecological regions based on these maps makes it possible to estimate qualitatively the ecological state of any coastal region. The Buor-Khaya Gulf of the Laptev Sea is used as a test case. Translated by Edward Torrey, Alexandria, VA 22308 from: Geomorfologiya, 1995, No. 4, pp. 23-34.     

MAPPING THE AVALANCHE HAZARD FOR MOUNTAINOUS AREAS OF AFGHANISTAN

The authors describe a procedure for the compilation of maps of the avalanche hazard in high-mountain regions of Afghanistan. The basic sources of information include space imagery (photographs and scanner imagery), weather station data, and other geographic information on relief, elevation, location of moisture sources, etc. The methodology features the compilation of series of increasingly more specific and informative maps and graphs regarding the avalanche hazard: terrain types, snow cover depth and seasonal extent, duration of snow cover and its elevational zonation, snow as a factor in avalanche formation, and summary map of avalanche hazard.

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).

FORECASTING LOCATIONS OF POTENTIAL INFESTATIONS OF FOREST INSECT PESTS BASED ON REMOTELY SENSED DATA

The authors describe a methodology for the compilation of a final map from remote sensing imagery (that can be rapidly updated) showing the location of likely future sites of infestations of forest insect pests. A series of preliminary maps is compiled, with each stage of mapping providing information used in compiling a map in the subsequent stage, in this case wind damage $$ resistance to further damage $$ locations of potential centers of insect infestation. The design and informational content of maps at all stages in the process are described. Translated by Elliott B. Urdang, Providence, RI 02906 from: A. S. Isayev, V. I. Sukhikh, Ye. N.

STUDY AND MAPPING OF LAND USE FROM REMOTE SENSING IMAGERY IN AGRICULTURAL MONITORING

A series of soil and agricultural land-use monitoring activities planned and carried out under the auspices of a local branch of the recently formed State Agro-industrial Committee is outlined. A general discussion of the place of agricultural monitoring within the overall system of environmental monitoring is followed by detailed examples of the use of space photography in preparation of photomapbases of local-level land use maps and in the compilation of the thematic detail of related agricultural maps.

USE OF TRANSFORMED CARTOGRAPHIC IMAGES IN URBAN CONSTRUCTION STUDIES

The authors describe how maps compiled according to non-spatial “metrics” or systems of scaling can be used in the support of urban planning and construction efforts. In particular, maps scaled according to travel time instead of ordinary distance reveal inadequacies not only in urban mass transit, but permit assessment of the rationality of urban land use as a whole, by demonstrating the degree of effort that urban residents must expend to perform such basic activities as shopping, the journey to work, and access to essential services. A methodology for the compilation of such maps is described. Translated from: Izvestiya AN SSSR, seriya geograficheskaya, 1987, No. 1, pp. 100-105.     

DIGITAL PHOTOGRAMMETRIC MODELING OF MOUNTAINOUS TERRAIN AND SNOW COVER DISTRIBUTION PATTERNS

This paper explores applications of digital photogrammetric modeling of mountainous terrain in forecasting snow depth and the meltwater avalanche hazard in a mining region of northwestern Russia. A series of initial maps (initial terrain points, relief of snow-flow centers, slope angles and orientations) provides successively more specific information, culminating in the compilation of a map of maximum snow cover depths at a center of water-saturated snow flows (representative reference site) on the northern slope of Mt. Aykuayvenchorr. Translated by Edward Torrey, Alexandria, VA 22308 from: Geomorfologiya, 1993, No. 3, pp. 75-83.     

Land productivity assessment and mapping through integration of satellite and terrain slope data

Evaluation and mapping of spatial variations of land productivity is very important for effective landuse planning. The present study was undertaken in watershed of the Song river (Dehra Dun district, U.P.), for assessing and mapping land productivity using modified Storie Index following integrated approach. This approach utilizes soilscape information (derived from digital IRS-IA LISS-II data), soil characteristics (field observed and laboratory analysed) and terrain slope information (obtained from Survey of India topographical maps). The approach consists of preparation of Storie Index productivity rating factors such as: A (soil profile character), B (soil texture), X (soil physical and fertility conditions), and C (land slope), and computerised integration of these maps to generate land productivity map. The results indicate that in the watershed 30.6%, 19.6%, 12.2%, 11.8% and 18.8% areas have been found to be under good, fair, poor, very poor and not suitable, land productivity classes, respectively.     

A CONCEPT FOR THE MAPPING OF MULTI-STATE SOCIAL AND ECONOMIC SYSTEMS

The paper investigates the use of maps in obtaining, based on the cartometric and geographic analysis of form, information about the content of multi-state social and economic systems. Examples of specially compiled maps of multi-state systems are described and various considerations in map design and compilation are discussed: scale selection, identification of typologies and design of map legends, principles for the location of geographic features on the map, and stages in cartographic research and mapping of multi-state systems.

MEDIUM-SCALE MAPPING OF THE FOREST ECOSYSTEMS OF MONGOLIA

The paper describes the organization and preliminary results of a joint Mongolian-Russian program for mapping forest vegetation in an area of Mongolia adjacent to the Russian border. The project involved the compilation of a map of ecosystems, which provided a base for a subsequently prepared map of ecosystem disturbance by humans. The paper includes a discussion of procedures followed in compilation of the legends of the two maps, as well as a detailed analysis of the spatial patterns of human disturbance revealed by analysis of the second map.

Integrated approach of using remote sensing and GIS to study watershed prioritization and productivity

Soil data obtained from soil resource inventory, land and climate were derived from the remote sensing satellite data (Landsat TM, bands 1 to 7) and were integrated in GIS environment to obtain the soil erosion loss using USLE model for the watershed area. The priorities of different sub-watershed areas for soil conservation measures were identified. Land productivity index was also used as a measure for land evaluation. Different soil and land attribute maps were generated in GIS, and R,K,LS,C and P factor maps were derived. By integrating these soil erosion map was generated. The mapping units, found not suitable for agriculture production, were delineated and mapped as non-arable land. The area suitable for agricultural production was carved out for imparting the productivity analysis; the land suitable for raising agricultural crops was delineated into different mapping units as productivity ratings good, fair, moderate and poor. The analysis performed using remote sensing and GIS helped to generate the attribute maps with more accuracy and the ability of integrating these in GIS environment provided the ease to get the required kind of analysis. Conventional methods of land evaluation procedures in terms of either soil erosion or productivity are found not comparable with the out put generated by using remote sensing and GIS as the limitations in generating the attribute maps and their integration. The results obtained in this case study show the use of different kinds of data derived from different sources in land evaluation appraisals.     

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.

Primitives as building blocks for constructing land cover maps

Land cover maps play an integral role in environmental management. However, countries and institutes encounter many challenges with producing timely, efficient, and temporally harmonized updates to their land cover maps. To address these issues we present a modular Regional Land Cover Monitoring System (RLCMS) architecture that is easily customized to create land cover products using primitive map layers. Primitive map layers are a suite of biophysical and end member maps, with land cover primitives representing the raw information needed to make decisions in a dichotomous key for land cover classification. We present best practices to create and assemble primitives from optical satellite using computing technologies, decision tree logic and Monte Carlo simulations to integrate their uncertainties. The concept is presented in the context of a regional land cover map based on a shared regional typology with 18 land cover classes agreed on by stakeholders from Cambodia, Laos PDR, Myanmar, Thailand, and Vietnam. We created annual map and uncertainty layers for the period 2000–2017. We found an overall accuracy of 94% when taking uncertainties into account. RLCMS produces consistent time series products using free long term historical Landsat and MODIS data. The customizable architecture can include a variety of sensors and machine learning algorithms to create primitives and the best suited smoothing can be applied on a primitive level. The system is transferable to all regions around the globe because of its use of publicly available global data (Landsat and MODIS) and easily adaptable architecture that allows for the incorporation of a customizable assembly logic to map different land cover typologies based on the user's landscape monitoring objectives     

Further Thoughts on the Representation of Vegetation on Topographic and Planimetric Maps

Abstract

The content of topographic and planimetric maps in relation to vegetation is examined with reference to the evaluation of contouring, the degree to which vegetation impedes movement, forestry, recreation, the planning of development projects, route planning, vegetation as base map information, and land use. This is an extension of the paper published in the Cartographic Journal, vol. 2, no. 2, and refers in particular to Africa South of the Sahara.     

COMMENTS ON K.A. SALISHCHEV'S PAPER

A method is described for the mapping of exogenous geomorphologic hazards (mass movements, frost heaving, suffosion, melting of permafrost) in the Lake Baykal area using space imagery. Black-and-white photography from the Salyut-4 space station (1:2,100,000 scale) was used as a base for the preparation of a series of maps depicting natural conditions (morphotectonic and physical geographic regions, faults, climate, dominant exogenous processes) used as a base for compiling a map of planning and engineering measures for the prevention and amelioration of geomorphologic hazards.
