Caracterização do uso e ocupação do solo através de imagem CBERS

Abstract

The present study aimed the generation of the soil use map and occupation of the basin of High Capivara - Municipal district of Botucatu (SP), that can be used as per-diagnosis of the physical aspects of the same. The characterization of the area they were used image Cbers - CB2CCD156/126, generated by the satellite CBERS2, bands 3, 4 and 5 of August 15, 2005, vertical aerial sharts of 2000, generated by the BASE - Aerial fotogrammmetry and Projectors S/A, with scale of 1:30000, System Geographical Information Ilwis 3.2 and field confirmation. The basin presents an area of 3348,27 ha and it is placed among the coordinates 760375,7467145,770545,7456915 of the spindle 22 of the Universal projection of Transversa of Mercator - UTM. The results allowed concluding that the basin is mainly occupied by pasture in more than 70%. The area of natural vegetation (savanna rangeland, esclerofilous woodland, semiciduos forest and riparium forest) they correspond at 22,73%. The images Cbers and GIS Ilwis 3.2 was effective for in the elaboration of the results, showing the immediate need of the elaboration of handling politics integrated for the preservation of the basin.
