Currently and in a more recurrent way, the trend of dispersed growth of the city is observed, which is why it is necessary to show that, although the city grows, causing a progressive disappearance of the differences between the parts and producing a new type of spatiality, the physical condition of the territory can still be emphasized (Paritá, 2013); Therefore, what can be the new way of interpreting and constructing limits and borders in a dispersed territory? It is a fact that, in the contemporary city, the identification and especially the measurement of undefined areas, increase the complexity of the metropolitan space due to the strong urban expansion of multiple heterogeneous spaces, characterized by their variety and difference, which are they move further and further away from the centralities of the city. Thus, the proximity of its parts is causing discrepancies that leave undefined spaces, which, based on the reformulation of the conceptualizations of limits and borders, are causing a new territory to be investigated. This is the theme that the document will address, in which it will reflect on the apparent end of a system and the beginning of a new territory, to understand what are the conditions of the urban contour that allow us to identify the many and different limits of a city that grows continuously, in such a way that its morphological representations can be recognized, named, and conceptualized.
