Urban morphology "implies 'form,' 'land use,' and 'density,' and has connotations with the shape, structure, pattern and organization of land use, and the system of relation between them" (Donnay, Barnsley, and Longley, 2001). It reflects the combination of complex special artificial areas such as buildings, roads, parks, gardens and even ecological systems of soil and water. To understand the dynamics and patterns of urban extend related with their interactions in heterogeneous landscapes, the spatial complexity needs to be quantified accurately, depending upon the morphological analysis and their relation with territory. Morphological analysis, which refers to the geometric characteristics of urban sites, illustrates its usefulness in determining the analogies between patterns of cities and their "physical" characters providing indicators of the aspect of settlement form and structure. Remote sensing might be helpful on the regional scale in evaluating the role that landscape play in connecting different settlements within urban regions and in separating the core city from the surrounding countryside. It used to map urban morphology of human settlements and monitoring urban growth (Batty and Longley, 1987). The information produced by remote sensing is spatially referenced through an implicit geometric location of the pixels. Various urban forms are potentially discernible using such devices, including linear objects (Sohn and Bowman, 2001). The aim of this paper is to classify, evaluate and compare different urban forms related to street networks and land characters, also considering the morphological typologies of urban settlements by moving from the spatial scale of a municipality to a wider territorial. The intent is to discover secure principals to find the most likely urban models of cities, taking topographical parameters into account. This research carried out focusing upon the metropolitan region of Barcelona, with urban sites defined according to the contiguity of artificial and administrative boundaries. The TeleAtlas and land activity classification deriving from Spot Imagery form the basis of this study. We will focus on the development of a methodology to classify the geometric properties and intrinsic space of urban settlements based on their characteristics and fundamental forms.
