| Abstract | Methodologies for Urban Agglomeration Growth Fractal Dimensions Estimate: a Contribution to Study of Sao Paulo Metropolitan Area Urban Expansion (1905 – 2001) The aim of this research is to evaluate and apply fractal dimension analysis methodologies to study the growing of metropolitan areas, using thematic maps and satellite images of time series. The Sao Paulo metropolitan area it was choose as test area to calculate fractal dimension variability over 96 years time series (1905-2001). Fractal dimension of the metropolitan area as a whole and urban expansion radial sectors it was calculated using the following fractal dimension methods: occupation urban density (Dd); area-perimeter (DPA) and perimeter-scale(DPR). The study was accomplished to thematic maps and orbital images from 1905 to 2001 that supplied information to estimate fractal dimensions from relations of density (Dd), areaperimeter and perimeter-scale (DPR). Fractal dimension of maps and images were to evaluate the time oscillation of empty urban spaces and the radial growing of urban perimeter. Over period analyzed, urban agglomeration as a whole show means values of Dd = 1.755 a trend to fill central areas and dilution of occupation density at peripheral ones; DPA = 1.400 related to tortuous urban boundary at time the urban peripheries were occupied; and DPR = 1.859 related to low spatial organization of urban structures. The radial growing fractal analysis was accomplished to eight urban radial sectors, whose show means values of Dd parameter over 1905-2001, as following: (I) Cantareira=1.829; (II) East Zone=1.898; (III) Maua=1.848; (IV) Ipiranga=1.852; (V) Billings=1.858; (VI) Santo Amaro/Interlagos=1.848; (VII) Castelo Branco/Anhanguera=1.859; e (VIII) Anhanguera/Bandeirantes=1.863. Among determinants factors on fractal behavior of sectors I, III, IV, V, VI e VIII, the results show the topographical, hydrographical and environment-legal constraints influenced the fragmented occupation and; for sectors II, III, IV, VI e VII the high occupation density was determined mainly due public incentives to industrial, business and road development. |
