                         land use for subsequent application for assessing soil loss of the 
                         municipality of Brotas (SP), through the Universal Soil Loss 
                         Equation (USLE). This is a highly relevant information to 
                         determining the anthropic factors of the equation, influencing 
                         directly to its results. The classification methods may lead to 
                         changes in the final results of the land use maps, and then the 
                         information generated from these. Two maps were generated for land 
                         use, the first one was obtained through classification of visual 
                         orbital image complemented by field surveys and cadastral 
                         information (location of cultivated areas from information 
                         obtained directly with companies that exploit the territory of the 
                         municipality) while the second was drawn up by supervised 
                         classification of images CBERS-2. The results show a reasonable 
                         similarity between the two procedures (Kappa Index of Agreement of 
                         62.11% overall, considering the classes of cover down), but no 
                         longer express some difficulties inherent in the definition of 
                         hedges associated with tree size vegetation (in the case, 
                         savannah, forest, orange and eucalyptus). In the case of the use 
                         of quantitative methods of analysis, as the implementation of 
                         USLE, it was found that the methods of classification may result 
                         in some variations in outcomes, but they were overcome with some 
                         corrections. From these corrections the two methods of drawing up 
                         the map of land use produced consistent and similar results.",
