                         environments in the world, is also an endangered ecosystem due to 
                         the severe land conversion. Therefore, it becomes mandatory a 
                         systematic and operational monitoring of the vegetation cover. 
                         Within this scope, in this study we evaluated the use of a linear 
                         spectral mixture model for mapping the Cerrado physiognomies. The 
                         model was applied to a dry season (July 2001) Landsat 7 ETM+ scene 
                         (221/71) converted to reflectance values, for an area 
                         corresponding to the Brasilia National Park. Three endmembers were 
                         acquired directly from the image (vegetation, soil, and shadow) 
                         and the respective derived images were capable of discriminating 
                         the major Cerrado domains (herbaceous, arbustive, and 
                         arborescent), with proportions ranging from 0.7 to 1.0. Currently, 
                         we are evaluating a different set of endmembers and the use of 
                         segmentation techniques as an attempt to more precisely map the 
                         Cerrado physiognomies. In addition, the impact of atmospheric 
                         contamination on the model output is being assessed as well.",
