		<abstract>This work was developed based on the techniques of remote sensing and geoprocessing, aiming to delimit the study area, water courses, preservation permanent areas (PPA), survey of land uses, hypsometry, slope and the relief type of the headwater of the Córrego Boa Vista microbasin, located in the municipality of Ipaussu, SP, Brazil. For cartographic elaboration, Quick Bird satellite images, made available by Google Earth Pro and topographic map with a scale of 1:50,000. Digital Elevation Model (DME) was elaborated from data generated by ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) with use of Computer applications such as ArcGIS 9.3.1 and 10.3.1 and Microsoft Office Excel-2007. It was verified that the study area occupies 453.3 hectares, with preponderance of agricultural and urban uses. It has an altitudinal variation of 50 meters from the lowest to highest level. Regarding the areas PPA, it was observed that about 40% is occupied by infrastructure and buildings (urban area). The slope of the study area is less than 30% and the predominant relief is flat and smooth corrugated. By means of the results obtained, it can be verified that the inadequate occupation of the PPA may affect the water availability of the springs in the long term and compromise the water quality of the water sources of the study area, with emphasis on the municipal lake José Nicolau which receives a large part of the upstream flow, coming from different uses, requiring the public power and the local population conservation practices.</abstract>
