Operação Arco Verde: Análise do desmatamento por meio de imagens do SIPAM R99/SAR - 2008

Considering the agreement between the Ministry of Environment (in portuguese, Ministério do Meio Ambiente - MMA), Brazilian Air Force and the Center Manager and Operating of System of the Amazon Protection (in portuguese, Centro Gestor e Operacional do Sistema de Proteção da Amazônia - CENSIPAM) imaging was performed of the 36 municipal districts in the Amazon Biome, the states of Amazonas, Pará, Mato Grosso and Rondonia, selected by the Entrance no28 of MMA, to January 24, 2008. According to this entrance, these municipal districts "will focus on priority actions to protect areas threatened with degradation and rationalization of land use in order to prevent, monitor and control illegal deforestation" (Arco Verde Operation). The images used in this study were obtained by aircraft remote sensing, R99-B, operating in the L and X bands, HH, VV, VH and HV, with a spatial resolution of 6 m, with 8 bits and 8 looks. The Brazilian Air Force was responsible for imaging and the CENSIPAM was responsible for data processing and analysis of deforestation of the images obtained by the sensor Synthetic Aperture Radar (SAR) of SIPAM. The analysis in this study showed the importance of using images R99/SAR indispensable for a more precise quantification of deforestation in the Amazon.Pages: 2997-300
