CONSIDERAÇÕES PARA O MONITORAMENTO DO USO DO SOLO COM DADOS MODIS PARA LONGOS PERÍODOS E EM ESCALA REGIONAL, E SUA APLICAÇÃO NA BACIA DO ALTO TAQUARI, MS/MT

Abstract

This paper discusses a methodology for the systematic classification of land use/land cover on a regional scale and over a period of several years. The basis of this methodology has been presented earlier by JONATHAN et al. (2005, 2006) and is centered on multitemporal analyses of data from the Moderate Resolution Imaging Spectroradiometer (MODIS), which is located on board NASA’s Terra and Aqua satellites and features high temporal frequency, extensive coverage, and extremely low costs for data acquisition. In this article, special emphasis is given to the evaluation of the possibilities and potential hindrances regarding the use of such a methodology for the pluriannual monitoring of land use and land cover. It is concluded that the monitoring of large regions for an extended period of time with low cost and high levels of automation is indeed a viable proposition. In this sense, the High Taquari Basin, located in the states of Mato Grosso do Sul and Mato Grosso, Brazil, is used as a study area for the analyses, so as to point out the relevance of the approach for detecting and quantifying phenomena such as deforestation and agriculture dynamics, which are themselves essential for the better understanding of the degradation processes within the Pantanal ecosystem.
