ResumoThere is a need for continuous monitoring of tropical forests due to the impact of deforestation on climate, biodiversity, and soil degradation. Current used methods are heavily based on visual interpretation of Landsat TM imagery or on digital classification using limited algorithms based on pixel-by-pixel analysis without contextual information. Hydrological and biogeochemical models require data on a georeferenced digital basis (geographical information system). This implies the needs for digitizing the maps from the visual interpretation which is a cumbersome and cost task and in some cases not even doable at any level of acceptable accuracy. The reason for this is the large number of small polygons that result from year-to-year assessment of deforestation. An alternative method of image segmentation based on a region-growing method followed by a per-field clustering algorithm based on Mahalanobis distance has proved to be feasible and reliable for deforestation assessment using Landsat TM digital data. This paper shows results for two test sites of the Amazon region. Comparison of results with conventional techniques (PRODES Project)showed good agreement, differences were smaller than 3 in area. The mapping accuracy was within acceptable errors for the 1:250.000 scale. Even though additonal testes are necessary to demonstrate the operational feasibility of this approach for large area surveys (e.g. 5,000,000 km2 such as the area of the Brazilian Legal Amazon)the techinical feasibility has been demonstrated.
