摘要：
A representative area of Manaus (Brazil) was evaluated using two geo referenced Landsat TM images from August 1990 and May 1992 with TNTmips; four classes of interest were identified and their spatial distribution evaluated through supervised classification method in three samples using two band combinations and cloud masking, the resulting maps were filtered for enhancement and noise reduction. The results showed the dispersion of located areas of forest recovery at a rate of 0.3% and of forest degradation at a rate of 0,6516 annually, confirming the cited complexity of the problem concerning its causes, tendencies and variability on time and space.
