Great transformations along the Spanish Mediterranean coast have generated considerable changes in the traditional structure of the landscape, far from the typical model of Mediterranean cities, and the rapidity of these modern dynamics has been a significant impact on the spatial patterns, also associated with the expansion of urban connections through the whole territory. The increase of large peri-urban areas, sprawled on the territory, and caused by uncontrolled, uncoordinated and unplanned growth, inevitably has brought the cancellation of clearly identifiable boundaries between the city and the rural areas. Spatial analysis, within quantitative geography and linked to the emerging field of regional science, represents a synthesis of urban and regional economics that is consistent with the complex sciences which dominate the simulation of urban form and functions. Most urban models deal with the city in terms of the location of its economic and demographic activities, but there is also a move to link such models to urban morphologies (Batty 2008). According with these concepts, the investigation, also supported by the use of technologies such as remote sensing and GIS, aims to complement the spatial analysis of regional development dynamics by classifying urban structures and quantifying some of main characteristics based on morphological features. 1. INTRODUCTION 1.1 Overview and motivations During the last decades, Spain has been undergoing important processes of urban growth, which has implied the consumption of large amounts of land, although the total population has hardly increased. This consequence has been very important along the coastal territory of Spanish Mediterranean side, where modern and actual dynamics of development are requiring new ways to analyze and quantify urban growth phenomena. Urban settlements, and their own formal characteristics, have to be wholly defined, being this basic information essential in spatial planning, in order to prepare the best practices apt to "respond" to the current challenges of territorial changes. How to extract and analyze information about residential settlements quickly and objectively is the foundation of the studies about economic and social development. The improvement of remote sensing technology provides a rapid tool for acquiring such information quickly (Chen et al. 2010). Quite a lot of useful techniques based on remote sensing technologies and methodologies for automatic classification of urban landscape have been developed, but there is still a challenge to find a generalized and objective methodology to be applied in different situations and geographical contexts. The use of automatic processes requires the reduction, as much as possible, of subjective interpretations and arbitrary interventions of analysts. 1.2 General objectives The investigation aims to find a relative fast and objective methodology to extract impervious areas on large landscapes and define different types of urban models, depending on morphological characteristics of land occupation. The work pretend to strengthen the idea that new technologies can really support all the process of planning both in the detection phase than in the analysis, and in order to support all the decisions which bring the final drafting of spatial plans. 1.3 Specific objectives First pursued result is the classification of several land cover categories along the Mediterranean side of Spain, through the use of satellite imagery and remote sensing techniques. It will be place emphasis on the impervious areas. After that we pretend to improve a methodology for automatic categorization of different typologies of urban texture, depending on their physical characteristics and based on a set of indicators such as size, shape, density and fragmentation of the urban settlements. Final result will be the automatic classification of three main morphological models of urban fabric: continuous, discontinuous, and scattered. It will be achieved by using statistical techniques such as factorial and cluster analysis. * Architect and PhD candidate in Urban and Architectural Management and Valuations at UPC, Universitat Politecnica de Catalunya, Barcelona Tech.
