The Companhia Energetica de Sao Paulo - CESP owns six hydroelectric dams in the state of São Paulo. The dams, both in its construction and in operation, cause some environmental impacts, most of them negatives, for example, the flooding in regions before not flooded, deviation of the river’s course, among others, bringing harm to flora and fauna of these environments. As a way to compensating these damages, the CESP has acquired a region that was influenced by Sérgio Motta Hydroelectric Plant Engineer, or Porto Primavera, and turned it into Reserva Particular do Patrimônio Natural Foz do Rio Aguapeí. By law it fits in a Conservation Unit, and thus should be contemplate for a management plan, ie, a multidisciplinary technical document which allows, simply, the practice of actions within and around in a sustainably way. This work aimed at developing a land cover map of the reserve for this plan can be made and executed more efficiently. Initially, the project included field visits and meetings with members of the CESP to be specified classes contained on the map. Later, we ran different types of classifications of multispectral images (TM / Landsat 5)... (Complete abstract click electronic access below)

The study aimed to obtain the land use of the watershed Stream São Caetano - Botucatu (SP), through the satellite image. The cartographic databases were: planialtimetric letter in digital format (IBGE) used in georeferencing, and satellite image. Geographic Information Systems (GIS) -IDRISI Selva was use to perform the image georeferencing and to do the final thematic map. In the software CAD - CartaLinx, it was performed the delimitation of the area under study (boundary, drainage network and areas of use and coverage). The land use of the watershed showed that pasture was the class which occupied most of the area, with 34.51% (1117,94 ha), the remainder of the area was urban (692,19ha), forests (809,79ha), cultures (599,96ha) and a very small part of reforestation (19,53ha). The use of remote sensing and geoprocessing were very satisfactory in the present work. Technologies must be increasingly used in agricultural and environmental studies, because technological tools, such as Geographic Information System (GIS), present speed, efficiency, reliable results, helping in increasing sustainability
