             abstract = "This paper aims at introduce a methodology developed to recover 
                         the Amazon deforestation occurred before 1997. The official 
                         mapping performed by FUNCATE team along PRODES project since 1988 
                         was built initially by visual interpretation over printed maps in 
                         order to compute the overall deforestation rates. After 1997, the 
                         deforestation maps were developed by a computer aid process, 
                         hereafter producing digital deforestation maps available year by 
                         year until today. Even the deforestation monitoring exists since 
                         1988, the amount of deforested area was large mainly in decade of 
                         1970. Thus, deriving deforestation maps for years prior to 1988 is 
                         crucial to social, environmental, climatic and ecologic studies. 
                         Given the cost and labor intensity of the visual interpretation 
                         performed by PRODES, it is of great value to apply an effective 
                         methodology in order to recover this untouched information to 
                         support studies about issues so far unaddressed. The methodology 
                         consists in download images with fine quality and correction and 
                         compare this data with data provided by PRODES. The main aim of 
                         the proposed deforestation detection maps is to develop a mapping 
                         very similar to the one executed by PRODES team, keeping 
                         confidence and consonance with their results, but automatically 
                         made. The results were after spread through a WEBSIG system 
                         developed by the project specially to address the social demand.",
