Acompanhamento multitemporal do crescimento urbano de Macaé com suporte de imagens históricas e Sistema de Informação Geográfica

Abstract

The disorderly growth of cities leads to the emergence of urban settings which do not provide citizens with basic needs recognized by the Brazilian Constitution. The discovery and exploitation of oil in the Campos Basin in 1974 made the municipality of Macaé (RJ) suffered profound changes in its spatial configuration, accompanied by accelerated growth and population density. The aim of this research is to develop application supported by a Geographic Information System, enabling dynamic thematic mapping with main focus on multi-temporal accompaniment of urban growth, located in the coastal zone of the municipality and its vicinity by using a series of historical images, composed of seven times, for the years 1956, 1966, 1976, 1989, 1999, 2001 and 2004. Thus, it was done digital processing of aerial photography and Quickbird system images, in order to validate the potential of SPRING, with operation guided through the steps of segmentation and supervised classification, obtaining results for the growth of the urban area council, within a period of 48 years approximately. SPRING is presented as an important tool in this process, with potential use in studies relevant to the management of cities. So, it was observed the possibility of effective implementation in stages of preparation of the master plan items and activities related to executive projects, both in its planning, and in its implementation.
