Résumé:
That work aimed the elaboration of the use shart of Rio Claro basin, Municipal
district of Pratânia and São Manuel - SP, seeking the adapted planning of the occupation of the
soil, used of System Geographical Information - SPRING 4.1 and of the images you originating
from of the satellite CBERS II, scene of 03/05/2005. The basin locates among the geographical
coordinates 22o
45' and 22o
51' of latitudes S and the meridians 48o
32' and 48o
38' of longitudes
W Gr., presenting an area of 4973,87ha. They were used for definition of the limit of the basin,
the planialtimetrics sharts of the IBGE of Pratânia and São Manuel. The used methodology
allowed to end that the images of the satellite CBERS was efficient sources of information; that
SIG-SPRING, was efficient and precise in the elaboration of the maps and in the calculation of
measures; that the gratuity and access easiness for acquisition of the images CBERS and of SIG-
SPRING for INPE allow the development of hundreds of works for the Country, being the
techniques of remote sensing and fundamental geoprocessing for the agility and precision of the
results. The results allow to infer that the watershed comes being preserved in environmental
terms, because it comes covered with more than 20% with forest covering of the type forest,
brushood and reforestation, because the minimum demanded by law is of 20%. The high index of
2
use of the earth for stands with pastures, brushoods and forests reflect the predominance of sandy
soils with low fertility, as well as the presence of 2/3 with agricultural use and pasture, they show
the regional predominance of the agricultural.
