The present work sought to the geotecnology use in the mapping of soil use in areas of PPA's, allowing their delimitations and diagnosis of possible humane interventions. The watershed with 4286,15ha, locates among the geographical coordinates 22o 31' 52" to 22o 38' 20" of latitude S and 48o 33' 40" to 48o 38' 47" of longitude WGr. The used cartographic bases were the planialtimetric chart for the georreferencing of the satellite image of 2011. GIS-IDRISI Selva was used in the supervised classification and the determination of the areas of the thematic map. The soil use showed that the culture of the sugar-cane occupies most of the area (81%), showing with that the predominance of the agricultural occupation in the area. The image and the use of GIS important tools were shown, supplying reliable results in a small interval of time. The obtained data will aid in the futures plannings of recovery of the area, because they made possible the verification that the area is not being preserved environmentally, link fact of presenting only 12,54% of forests, and the minimum demanded by the legislation of the Brazilian Forest Code effective is of 20%.
