This study aimed to diagnose the use and occupancy of permanent preservation areas (APP) in the watershed of the stream Lageado localized in Uberaba (MG), based on digital images of the satellite
ResourceSat-1, Datum WGS84, Zone 23 and the corresponding date 05/04/2012. To develop this work were mapped areas of permanent preservation with the use of a classifier digital supervised and identified instances of conflict of use, with reference to cool the Brazilian Forest Code (Law no. 4771/1965), Law 14309/2002 (forestry policy and protection of biodiversity in the state of Minas Gerais) and resolution no. 303/02, CONAMA. This article analyzed through quantitative parameters and with the use of Geographic Information Systems to maintain permanent preservation areas, as recommended by the legislation widths along the water bodies. The results showed a deficit of preserved areas along the riverbanks of approximately 2,17 Km ², that are not in accordance with the law. The area occupied by the Agriculture improperly is 0,8257 Km ², livestock Km ²
1,3082, 0,0151 km ² urbanization, mining 0,0216 km ² and exposed soil within the APP 0,0117 km ². Thus, predominates in the Watershed study in the occupation of Permanent Preservation Areas for grazing areas.
