STUDYING A MEDIUM SIZE CITY GROWTH IN BRAZIL AND ITS CONSEQUENCES USING GEOTECHNOLOGIES

摘要

The city of Sao Jose dos Campos is the most important city located at the Region of Paraiba River Valley, considering the process of industrialisation. It was, and it continues being, marked by an intense industrialisation, which started to command the growth of the municipal district after the decade of 50. The city grew without the local government could control the process definitively. In this sense, this research detected and evaluated the changes happened in the urban space of the city of Sao Jose dos Campos and analysed the environmental occupation, as a consequence of the process of urban growth without a town planning, using remote sensing data and techniques and a geographical information system (geotechnologies). This research will analyse the period of larger urban transformation, in respect to the industrialisation and recent economical changes: 1953 to 1997. A 3D model of the urban perimeter and a slope map have been produced to investigate how the city has occupied the site, which was assessed using digital topography data. The urban area was mapped using aerial photography obtained in 1953, 1962, 1973, and 1985, and SPOT Pan image, obtained in September 1997, all of them in scale of 1:25,000. The idea was to verify the city performance considering the relation between growth and site (environmental limitations) using the geotechnologies performance.
