Segmentação e classificação supervisionada para identificar pastagens degradadas

Lucimar MoreiraEduardo Delgado Assad

One of the major environmental issues in the Brasilian Cerrado region is the identification of the levels of degradation in the cultivated pastures. About 50 million hectares of Cerrado is currently covered by cultivated pastures, with different degradation levels. This paper assesses the performance of supervised classification per region for identifying different degradation levels in cultivated pastures. The study area is located in the córrego Lamarão Watershed , Federal District. The satellite images were processed by using the SPRING/INPE Geographical Information System. We were able to identify five levels of cultivated pasture degradation.
