             abstract = "The Upper Acre River Basin of Bolivia, Brazil and Peru in the 
                         center of southwestern Amazonia covers 7590 km2 and is one of the 
                         few tri-national basins in Amazonia. The PRODES method developed 
                         at INPE for the analysis of deforestation was adapted and tested 
                         for use in measuring forest cover in the basin. The test used the 
                         Landsat TM+ scene 002/67 of 10Aug02 and subsets. Deforested area 
                         differed by 4% between analysis at INPE and the unmodified PRODES 
                         method used for this study for the entire scene and <3.5% for the 
                         subsets. The modification of the PRODES method included: 1) no 
                         application of the prior deforestation mask; 2) spatial resolution 
                         of 30 m in place of 60 m; and 3) minimum area of 0.36 ha rather 
                         than 5.76 ha. The modified PRODES method when applied to the 
                         entire Landsat scene resulted in a 14% small deforested area. In 
                         comparison with a Quickbird scene of 21Jun02 used for accuracy 
                         assessment, the modified PRODES method overestimated the forest 
                         area by 16% and underestimated the deforested area by 4%. The 
                         total area deforested in the trinational Upper Acre River Basin, 
                         using the modified PRODES method was 13% (1014 km2) in 2002.",
