                         are extremely important for the selection of adequate strategies

                         management. This work presents the results of a set of digital 
                         image processing techniques used for the environmental sensitivity 
                         index mapping. Multispectral transformation (band fusion via IHS, 
                         principal component, and spectral mixture model), band ratioing, 
                         segmentation and unsupervised digital classification were applied 
                         to ETM+ Landsat 7 imagery in order to optimize the mapping 
                         process, making it quicker and more objective. The best mapping 
                         results were achieved with the segmentation and classification of 
                         the fused panchromatic and multispectral images via IHS, followed 
                         by raster editing.",
