             abstract = "In the last decades, SW Amazonia presented an intense dynamics of 
                         changes of land use, mainly due to cattle raising activities 
                         (fazendas)and to agricultural settlement projects. The objective 
                         of this study is the analysis of the feasibility of multitemporal 
                         RADARSAT data to discriminate land use / land cover types, at a 
                         sector of SW Brazilian Amazonia, in Acre State. In order to 
                         perform this work, RADARSAT scenes from 2 distinct hydrologic 
                         periods were used: end of rainy season (April/May)and end of dry 
                         season (October), and the following thematic classes were defined: 
                         primary forest, secondary vegetation at different development 
                         phases, pastures at different phenological conditions and recent 
                         burned areas. The methodology used, included the following steps: 
                         antenna pattern correction, speckle reduction and linear stretch 
                         enhancement, and RADARSAT integration with TM bands 3,4 and 5 
                         through an IHS transform. Aerial color photographs at 1:20,000 
                         scale and physiognomicstructural profiles of the vegetation types, 
                         were also used. The results obtained indicate that the radar 
                         backscatter coefficient ( ) is very sensitive to rainfall 
                         occurring in the eve of the acquisition date, what can be seen at 
                         the deforested areas.",
