Dispersed growth and its metropolitanization process

Abstract

The growth of the city of Boston has strengthened in the last two decades, developing an urban model composed mainly of suburbs of low and medium density, a characteristic pattern that mentions the theories of "Urban Sprawl". Therefore, this work will pay special attention to the gaze of James O'Connell, who tells us the historical process, the social effects, the events and the different public-private administrative decisions that have led her to become one of the largest metropolis in the world today. The interaction value is calculated to determine the level of polycentrism between municipalities, and an approach to the morphological analysis of discontinuity is proposed, one of the physical patterns that idealize urban expansion, proposed by Galster, et al (2001). To do this, the existence of “Sprawl” in the Boston metropolitan area (MAPC) will be analyzed based on the characterization of urban fabrics. For this it is necessary to obtain the growth of the multitemporal urban spot of the metropolitan area, to objectively assess the land consumption in the territory. To carry out the procedure, satellite image processing from NASA Landsat 5 TM was used, using SIG (remote sensing) technology, years 1985, 2002, and 2011 respectively. The objective is to calculate the BU (Build-up Index) or constructed area index, which shows that the higher the construction index, the lower the green area index (He, et al, 2010). It is necessary to observe how the soil cover changes (water and vegetation in relation to the artificialized surfaces), the results derived from this analysis will also be manifested in the study of the tissues revealing certain patterns of discontinuity.
