USE OF REMOTE SENSYNG AND GEOPROCESSING TECHNIQUES IN THE TAQUARI VALLEY/ RS ENVIRONMENTAL ZONING

Abstract

The maps, historically, have been used as primary source of information, being a visual instrument of the human perception and a way to get the register and the analysis of the landscape. In this context, this paper aims to evidence the use of remote sensing and geoprocessing techniques with sights to elaboration of the environmental zoning of the Taquari Valley, region formed by 37 cities and located at Rio Grande do Sul State. The cartographic base used to generate the thematic maps was extracted from topographical maps elaborated by Geographic Service of the Army, in 1/50,000 scale. Landsat satellite images were used to generate the land use and land covering. The environmental zoning evidenced the lack of planning of land use and land covering in the study area. The results presented in this paper are important in the attempt to surpass the problems of the development and to reduce the deterioration of the environmental quality in the Taquari Valley.
