             abstract = "The area under study, located in SW Amazonia, Acre State, Brazil, 
                         has been studied in the last few years, using both optical 
                         (TM-Landsat)and microwave (airborne C-band SAR, ERS-1, 
                         SIR-C)remote sensing data. Recently data from RADARSAT in both 
                         Standard and Fine mode beams were acquired. The objective of this 
                         study is to show the capabilities of RADARSAT and merged 
                         RADARSAT/Landsat TM images for land use/land cover discrimination 
                         in SW Amazonia. The concept of the study is to analyze the 
                         feasibility for systematic mapping of similar land use / land 
                         cover features in the tropical rainforest areas. Two distinct 
                         periods of the tropical hydrological cycle, i.e. at the end of 
                         both the rainy (April/May)and at the dry season 
                         (September/October)were investigated. The main features 
                         discriminated were: phenological conditions of pasture, recent 
                         forest burning, and changes in regrowth patterns. The separation 
                         of small (50-100 ha)and large (200 to several 1000 ha)clearing is 
                         also feasible. Furthermore, a stratification of primary forest and 
                         regrowth is also in progress. The RADARSAT products used were 
                         pre-processed at CCRS. It consisted of scaling the data from 16 to 
                         8 bit real integers, antenna pattern correction, attenuation of 
                         speckle and linearly contrast stretch. The RADARSAT data was then 
                         registered to Landsat TM Bands3, 4 and 5 with IHS/RGB transforms, 
                         to integrate the data. This study is supported by both color 
                         aerial photographs (scale 1:20.000)and physiognomic-structural 
                         profiles of the vegetation types.",
