                         degradation caused by either selective logging or fires in 
                         tropical humid ecosystems. Our study area is located in the Mato 
                         Grosso state of Brazil, in a region known as Deforestation Arc. 
                         Eight consecutive Landsat Enhanced Thematic Mapper Plus (ETM+) 
                         images were available over this study area during the dry season 
                         of 2002 (from June to October). The proposed method is based on 
                         multi-temporal image segmentation and classification of a data set 
                         of soil and shade fraction images derived from Landsat ETM+ 
                         imagery. Areas of selectively logged forest are identified and 
                         mapped from the soil fraction images, whereas burned forest areas 
                         are identified and mapped from the shade fraction images combined 
                         with a map of deforestation happening during 2002. The main 
                         benefit of this approach is the capability to discriminate 
                         selectively logged forest from burned forest, which is a very 
                         important issue for estimating carbon emissions from forest
