Avaliação do método aplicado ao mapeamento de cicatrizes de áreas queimadas utilizando um Sistema de Informação Geográfica - SIG

Considering the importance and the interest of the scientific community have to develop an efficient method of detection of scars of burning areas, this work shows the procedures using satellites images and free software. The images are from MODLAND/ NASA products and software Spring/ INPE. The study areas sampled selected are inside of Legal Amazonia since it is possible to state that the degradation process caused by fire in this area is a constant. The present paper aims to compare unsupervised classification methodology, automatically performed with the same results in the same classification after the corrections made by an interpreter. By this way is possible to evaluate the feasibility of the computing and human efforts in improving the quality of data.
