ABSTRACT
Starting from complexity theory and self-organization, we focus in this chapter on an alternative reading of the morphology of emerging urban patterns by using a cross-scale approach based on fractal geometry. First, we give a general overview of the peculiar properties of the approach introduced. Then we focus on a new class of geometric reference models with which to identify the type of information that can be obtained about the spatial organization of cities. This leads us to morphological properties of a number of metropolitan areas. They are discussed and linked to their geographical and historical contexts. This allows us to come back to the underlying generating processes and the extent to which they are self-optimizing. This discussion introduces a new planning context based on fractal geometry through which to combine the different aspects of sustainable development harmoniously within the framework of a decision support system.
