The Use of LANDSAT Data to Monitor the Urban Growth of Sao Paulo Metropolitan Area,
INSTITUTO DE PESQUISAS ESPACIAIS SAO JOSE DOS CAMPOS (BRAZIL)
The urban growth monitoring of Sao Paulo Metropolitan region has been done by conventional techniques which involve a high cost sistematic control. On the other hand, the orbital remote sensing allows a continuous land use control at lower cost. For being under governmental control the region located between Billings and Guarapirange reservoirs was chosen as test site for monitoring urban growth through LANDSAT data. Mapping the urban growth over the period from 1977 to 1979 and identifying the problematic urban areas with several LANDSAT products constitute the basic aims of this work. Visual and automatic interpretation techniqes were applied to the data. Computer compatible tapes CCT of LANDSAT multispectral scanner data were analyzed through the Maximum Likelihood Gaussian algorithm. The results pointed out the feasible monitoring of fast urban growth by remote sensing techniques leading to an efficient urban planning and control.
