REMOTE SENSING IN THE STUDY OF LANDSCAPE STRUCTURE

Applications of remote sensing, in particular space imagery, in the study of the physical structure of landscapes are described. Special attention is paid to space imagery's capacity for instantaneous analysis of extensive areas, its potential for combined use with more traditional methods, and the multiscalar quality of the data obtained. Joint use of a variety of image products and imaging sequences provides diverse information which can be integrated for a more comprehensive understanding of landscape structure in a variety of physical environments.

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.

THE USE OF REFLECTANCE OF OIL-POLLUTED SOILS IN MONITORING FROM REMOTE SENSING IMAGERY

A method is presented whereby soil reflectance on remote sensing imagery is used to estimate the level of soil pollution by oil production operations. This method can be used in lieu of the dangerous and toxic solvents now widely employed, and has the additional advantage of applicability to much larger areas. It is based on the construction of a graph and derivative equations depicting the relationship between the spectral reflectances of soils and the soil hydrocarbon content of sample soil plots.

THE STUDY OF SOIL-VEGETATION DYNAMICS THROUGH REMOTE SENSING

Remote sensing imagery at widely varying scales is used in the analysis of the soil-vegetation cover of the west-central Siberia. Space imagery and smaller-scale air photographs initially are used to divide a study area into basic soil-vegetation complexes based on the criterion of figure outline. The internal structure of the complexes are then analyzed in greater detail, using larger-scale air photographs and a standard interpretation key based on selected field observations. Tonal-textural variations establish the ecological affiliations of separate elements within each complex and their dynamic states at a particular point in time.
