Utilization of GIS in the interrelation of physical-natural and social-economical data of Campinas administrative region: A methodological proposal.

Abstract

he aim of this study is to develop a methodology for the integration of data from the physical-natural and social-economical background, using, for this, the Geographical Information Systems (GIS). Also the possibilities of cartographic up-to-dating of data by digital method are evaluated. The study area was the Campinas Administrative Region and the main data was the sugar cane distribution in the region, in 1980, digitized from the Land Utilization Chart of São Paulo State (IGC, 1980), using SGI/INPE software. Data about planted area and production of sugar cane (Crops and Livestock Census - IBGE, 1980) were structured in a data bank. A chart of types of soil (AGRICULTURE MINISTRY, 1960) was also digitized. The integration, using IDRISI system, of the cartographic and statistical data alloved identify and to map the sugar cane productivity in relatio of agricultural soil potential and the differences between statistical and mesured data. Key-words: Geographical Information Systems, cartogram, spatial analysis, produce and productivity of sugar cane, data bank.
