                         for monitoring land cover changes in Acre State, Brazilian 
                         Amaz{\^o}nia. The 2000 Landsat ETM+, the 1990 Landsat TM, and 
                         1980 Landsat MSS were used. The 2005 and 2007 MODIS images were 
                         also used to map deforestation occurred during the recent years 
                         and to map burned areas occurred in the 2005 dry year. The Landsat 
                         and MODIS images were converted to vegetation, soil, and shade 
                         fraction images. Then land cover maps were obtained by digital 
                         classification of these fraction images. The deforestation 
                         increased 7,114 km2 from 1980 to 1990, 4,900 km2 from 1990 to 
                         2000, and 3,258 km2 from 2000 to 2007. It also showed that about 
                         2,815 km2 of regrowth areas were observed in the 2000 ETM+ images. 
                         The analysis of MODIS images showed that 3,700 km2 of deforested 
                         areas and 2,800 km2 of forested areas were burned in Acre State in 
                         2005. These information are critical for regional and global 
                         environmental studies and for efforts to control such burning and 
                         deforestation in the future.",
