Abstract

The objective of this work was to survey the land use at Limoeiro watershed placed on the Presidente Prudente and Álvares Machado counties in the West of the São Paulo State. The related survey was effected using an image of TM sensor of the satellite Landsat 7 and the Geographic Information System Idrisi. The result of the survey was statistically analyzed through the kappa index. After that, it was digitalized the level curves of the watershed which were interpolated to supply the slope classes of all the studied area. Subsequently, the slope spaces were crossed with the land use with the purpose of verifying the main land uses in each slope class. It was observed that cattle and the urban area are the main ground occupations in the watershed. It was still observed that the predominant slope spaces in the studied area are those between 3 and 12 percent.
