The limited existence of continuous spatiotemporal data always imposed considerable restrictions on transversal and diachronic approaches to the urban phenomenon. However, recent technological advances daily increase colossal databases with explicit geographic information (e.g., satellites, social networks, official data), enabling the multiplication of case studies. So, the deductive logic, hegemonic until then, is replaced by the inductive one. This approach applied from bottom-up perspective highlights local particularisms. Born even before the splendidness of 'Big Data', the synoptic and repetitive view of the Earth provided by Remote Sensing constitutes a key element in the reinterest and in the methodological and conceptual renewal of Urban Studies verified in the begin of the new millennium. In particular, the chronogeographic focus that is given to studies of urban morphology. Along with this, satellites multispectral view provides diverse information (e.g., soil moisture, surface temperature, pollution), which extends far beyond the mere extraction of urban fabric. In this sense, we seek to highlight the mutations that Remote Sensing - anchored on Geographic Information Systems - promoted in the Urban Studies. We focus on Geography domain were the integrated approach of the urban ecosystem is maximized.
