             abstract = "Polarimetric signatures for different tropical land covers were 
                         extracted from RADARSAT-2 data. Subsequently, the data were 
                         classified. The objective of this work was to assess the potential 
                         of RADARSAT-2 polarimetric C band data on land cover mapping. 
                         RADARSAT-2 data were acquired over Tapajos National Forest, a 
                         tropical forest reserve in Brazil, and surroundings, in September 
                         2008. A field campaign was conducted during the same week of the 
                         SAR data recording. Polarimetric signatures for the different land 
                         covers were extracted for co- and cross-polarised bands and 
                         results indicated the variety of scattering mechanisms in the 
                         study area. Following that, the coherence and covariance matrices 
                         were used for the Freeman-Durden target decomposition, which 
                         decomposed the image targets in new bands representing the main 
                         scattering mechanism in the resolution cells corner reflection, 
                         volumetric and superficial. Data were later classified by a 
                         k-means-Wishart classifier. The bands representing volumetric and 
                         superficial scattering helped discriminating vegetated and 
                         nonvegetated areas. Classification accuracy reached around 80% for 
                         forest and pasture/bare soil classes. For the remaining classes, 
                         the classification accuracy results did not reach 50%.",
