Nuevas geografías urbanas en Santiago de Chile 1992 - 2012. Entre la explosión y la implosión de lo metropolitano.

Abstract

Within the framework of a discussion on the redefinition of the urban and the growth trends of the city of Santiago in the last decades, this work analyzes the influence of Santiago on its regional environment and the urban growth resulting from explosion and implosion processes. in the period 1992 - 2012 that have made the real limits of the Metropolitan Area of Santiago more complex. First, through the application of the OECD’s Functional Urban Areas methodology (2012) for the years 2002 - 2012, the limits of the city were redefined from the 34 traditional communes to 48 communes that are divided into a nucleus and a hinterland, which generates a better territorial understanding of the metropolitan phenomenon. Secondly, the supervised interpretation of satellite images allows us to identify a new urban form characterized by a new geography, in which the growth within the city and to the periphery has taken place in parallel. The application of mixed methodologies that analyze the urban allows us to understand that urbanization is a process, in which the form is only the result of many factors.
