Abstract
Different aspects of enhancing the efficiency in using the ''Almaz'', ERS-1, and ''Landsat-TM'' satellite data for the documentation of tund ra ecosystems are discussed. Program modules for preprocessing ''Almaz '' satellite data were developed, which make it possible to control th e spatial resolution value, as well as the shape of the synthesized di rectivity diagram (SDD), and to suppress the speckle noise with the he lp of a set of adaptive filters. Different systems for classification of the earth surface are proposed, based on the data on the a priori k nown types of tundra vegetation and surface, and the efficiency of app lying these systems in comprehensive treatment of terrestrial and sate llite data is estimated. The results of classification of tundra ecosy stems are presented.
