Abstract


This study aimed to analyze the current  land use of  the Alto do Rio Pardo - Botucatu (SP),  through data collected on bands 3,  4 and 5 from Landsat 5 “Thematic Mapper” sensor.  The image date is June 8 1997, corresponding to orbit 220, point 76, quadrant A.  The image was used in colorful compositions, scale 1:50.000 and digital format. It was done a visual interpretation on a photographic paper image and a field check.  To confirm the land use, each band from Landsat image was examinated.  According to the results obtained in the research the conclusions are: a) the data collected by the “Thematic Mapper”  of Landsat have  valuable  information  for diff  erent  targets  of  land occupation,  therefore  very  useful  in mapping  studies  of current land usage; b) The results of visual analysis on the data from Landsat, presented that the type of pasture plant were the most signifi  cant occupying 69.70% of the area; c) Through visual analysis of data from Landsat it was possible to verify that there is environmental preservation only in areas of forest gallery occurrences.
