                         inicialmente. Foi verificado que, al{\'e}m do erro de registro

                         haviam outros tipos de erros oriundos dos algoritmos do software

                         PRODES digital tivessem uma futura atualiza{\c{c}}{\~a}o e/ou

                         apresentar uma metodologia para corrigir as distor{\c{c}}{\~o}es 
                         observadas entre os dados de mapeamentos obtidos pelo projeto 
                         PRODES digital no ano-base de 1997 e a atualiza{\c{c}}{\~a}o dos 
                         incrementos de desflorestamento para o per{\'{\i}}odo coberto 
                         pelas imagens TM de 1997 e de 2000. ABSTRACT: The transposition of 
                         deforestation information generated from the Landsat images in 
                         subsequent years is not simple as it was thought initially. It was 
                         verified that, besides the image registration error that was 
                         around two pixels (60m)in average, there were other types of 
                         errors generated by the algorithms of the SPRING software. These 
                         problems commit seriously the main advantage of digital PRODES 
                         that is to eliminate the geometric distortion errors and the 
                         consequent lack of georreferencing and adjustment of the 
                         deforestation polygons very common in the visual interpretation 
                         (analogical)method. This situation would not admit that the data 
                         generated in the digital PRODES would have a future updating 
                         and/or integration with other information due to the introduced 
                         geometric errors. Considering the observation above, the objective 
                         of this work is to present a methodology for correcting the 
                         distortions observed between the mapping data obtained by the 
                         digital PRODES project in the 1997 base-year and the updating of 
                         the deforestation increments for the period covered by the 1997 
                         and 2000 TM images.",
