Geoprocessing in the generation of thematic maps aiming at environmental planning

Abstract

The rising of the soil use in a certain area is fundamental for the understanding of the organization patterns of that determined space. The present work had as objective to evaluate the applied geoprocessing in the generation of thematic maps aiming at environmental planning, through the Geographical Information System Idrisi Andes 15.0. The Stream Comur watershed is placed in the municipality of Botucatu (SP) and among the geographical coordinates: latitude 22o 44’ 42” to 22o 48’ 12” S and longitudes 48o 23’ 04” to 48o 25’ 54” W Gr, with an area of 1458.4 ha. The results enabled to infer that the slope classes from 0 to 3% and from 3 to 6% which exist in the watershed represent more than 67% of the area and the one from 0 to 20% prevailed in more than 80% of the watershed. The areas with relief smoothly wavy (3 to 6%) they were the most representative (36.92%). the unit of soil Latossolo Vermelho Distroférrico happened in more than 45% of the area. The GIS was an excellent and indispensable tool, because it facilitates and it activates the obtaining of the data, besides enabling its storage, which can be used for other analyses in future geoenvironmental planning.
