                         decomposition techniques and the polarimetric ratios applied to 
                         the ALOS/PALSAR-2 satellite polarimetric images to discriminate 
                         the land use and land cover classes in the Tapajos National Forest 
                         region, Para State. Three full polarimetric ALOS/PALSAR-2, level 1 
                         single look complex scenes were selected to generate the coherence 
                         and the covariance matrices to derive the Cloude-Pottier and the 
                         Freeman-Durden target decomposition attributes. From the 
                         radiometrically calibrated PALSAR-2 images, we generated the 
                         backscatter coefficients, the cross polarized ratio (RC; HV/HH), 
                         the parallel polarized ratio (RP; VV/HH) and the Radar Forest 
                         Degradation Index (RFDI). The images resulting from these 
                         polarimetric attributes were processed by the Maximum Likelihood 
                         (MAXVER) classifier coupled with the Iterated Conditional Modes 
                         (ICM) contextual algorithm. We found that the classifications 
                         derived from the target decomposition attributes, mainly from the 
                         Cloude-Pottier technique, with a Kappa index of 0.75, presented a 
                         significant higher performance than those derived from the RC 
                         ratio, RP ratio, and RFDI.",
