Environmental urban quality index from satellite images and census data, and land use/land cover change analysis in Santana de Parnaíba


Certainly, in Brazil, the growth of cities is important since 1970, in this time the population of Brazilian cities surpassed the population of rural areas. This tendency initiated in 1970 did not show reversal. Today, closely, 81 per cent of Brazilian citizens live in cities after 30 years.The migratory processes originated the apparition of peripherical zones on Brazilian metropolis of southeast. In this areas emerge many social and environmental problems, insipient residences, build by auto-construction processes, slums, elevated index of illiteracy and violence. The principal aspects of the peripherical zones in metropolis are the buildings or the elevated density of them. Those areas can be studied by means of remote sensing technology products. Satellite images like as IKONOS 2 permit the elaboration of detailed maps of this peripherical zones. Many researchers attest the potential of the application the satellite data on urban environment. The development of this project intends to delineate one set of procedures to obtain environmental index from satellite images and to associate them with census data. The aim of this research is to obtain the characterization of the people’s life quality of the peripherical zones of São Paulo Metropolitan Region. (AU)
