                         for monitoring land cover changes in Acre State, western Brazilian 
                         Amazonia. For this study, the 2000 Landsat ETM+ (ETM+, Enhanced 
                         Thematic Mapper Plus), the 1990 Landsat TM (TM, Thematic Mapper) 
                         and 1980 Landsat MSS (MSS, Multispectral Scanner System) were 
                         used. The 2005 and 2007 Terra MODIS (MODIS, Moderate Resolution 
                         Imaging Spectroradiometer) images were also used to map 
                         deforestation that had occurred during the recent years and to map 
                         burned areas that occurred in the 2005 dry year. The ETM+, TM, MSS 
                         and MODIS images were converted to vegetation, soil and shade 
                         fraction images, using linear spectral mixing model, in order to 
                         reduce the data volume for digital processing. Then land cover 
                         maps were produced by digital classification of these fraction 
                         images. The results showed that deforestation increased by 7100 
                         km2 from 1980 to 1990, by 5100 km2 from 1990 to 2000 and by 3300 
                         km2 from 2000 to 2007. About 2100 km2 of vegetation regrowth areas 
                         were observed in the 2000 ETM+ images. The analysis of 2005 MODIS 
                         images showed that 3700 km2 of deforested areas and 2800 km2 of 
                         forested areas were burned in Acre State in 2005. This kind of 
                         information is important for regional and global environmental 
                         studies and for efforts to control such burning and deforestation 
                         activities in the future.",
