On the relationship between the sky view factor and the land surface temperature derived by Landsat-8 images in Bari, Italy
2015
This study investigates the impact of landscape composition and urban morphology on land surface temperature LST in the city of Bari, Italy. For this purpose, correlation between sky view factor SVF and LST was done assigning weights to the output results and moreover expressing the latter according to the four main surface classes of the Corine land cover CLC classification method. To do this, several daytime Landsat 8 and night-time Landsat 7 ETM+ images acquired during different months of the year were used to retrieve LST by using the radiative transfer equation. The results show a positive relationship between LST and SVF, and this trend is emphasized particularly in the more dense urb…
Comparing the morphology of urban patterns in Europe
2004
The sprawling urban patterns typical for the outskirts of many europen metropolitan areas seem to be amorphous and it is difficult to find references for describing them. However, for managing sprawl it seems important to have quantitative descriptors, which allow distinguishing different types of urban patterns and which are less ambiguous than traditional density measures. a better knowledge of these patterns should also point to the underlying context of urbanisation at their root. More concretely: to what extent are planned patterns different from less planned ones? Do planned or unplanned patterns show comparable morphological features?

Muratorian urban morphology: the walled city of Ahmedabad
2015
This paper investigates the complexity of the urban fabric, from the urban scale to the building and neighbourhood scale, by using the concepts and tools of urban morphology according to the Muratorian School. Specifically, basic concepts such as ‘urban polarities’, ‘routes hierarchical system’ and ‘building neighbourhood’ are used. They are deployed in the walled city of Ahmedabad, India, which has a rich architectural heritage clearly recognizable in Indo-Islamic monuments and particularly in aggregative structures called pols.
School choice criteria and school segregation in the city of Valencia
2022
El objetivo de este estudio es conocer cuáles son los patrones que intervienen en la elección de centro escolar y detectar los factores sociodemográficos, económicos y de localización que subyacen tras ellos. Para ello, se ha realizado una encuesta a la demanda potencial de los centros públicos que imparten el segundo ciclo de educación infantil en la ciudad de Valencia. Los resultados indican que el principal criterio de elección de centro escolar es la proximidad entre el hogar y el colegio, y que el modo de desplazamiento más utilizado es el peatonal. Sin embargo, los costes de desplazamiento y los medios utilizados están directamente relacionados con las características socioeconómicas …
L’Infrastruttura che cura : scenari architettonici di trasformazione per gli ecosistemi ai margini della circonvallazione di Palermo
2022
Nella prospettiva circolare di produzione, consumo e rigenerazione ormai divenuta indispensabile, costruire si afferma come uno degli atti a più elevato impatto ambientale. Per un’autentica mutazione, l’architettura deve affrontare il progetto attraverso un approccio interrelato e intendere ogni atto di costruzione come un atto di co-costruzione. Ciò significa comprendere la Terra non come somma di luoghi, ma come sistema inscindibile di viventi e materie che non possono evolvere separatamente o in una condizione di squilibrio determinata dal predominio di una specie sulle altre. Su questo sfondo, l’articolo discute un punto nevralgico nel ripensamento in chiave ecologica dei territori antr…
La morphologie des tissus urbains et périurbains à travers une lecture fractale
2005
Urban expansion produces an irregular urban fabric. This phenomenon influences areas which are distant from urban centres, a problem for sustainable development. Solutions proposed to reduce urban expansion are modelled on the pattern of the compact town. Generally, it is believed that these solutions are unacceptable to the people concerned. In this article we present an alternative approach to the study of urban fabric, which shows that, despite their irregular form, it is possible to describe their development using fractal analysis. This permits understanding of the socio-economic causes of this process and the development an alternative conceptual approach to the management of urban ex…
Urban morphology detection and it's linking with land surface temperature: A case study for Tehran Metropolis, Iran
2021
Abstract Expansion of urban areas and alteration of natural land cover exacerbate the local climate change. To find out the effect of land cover changes on the local climate, in this study, the Local Climate Zone (LCZ) concept was utilized to detect urban morphology in Tehran Metropolis. LCZ and Land Surface Temperature (LST) can be identified and classified based on available remote sensing products. Firstly, LCZ maps of Tehran metropolis were extracted using Landsat imagery, and secondly, relationships between LCZ and LST were explored for three years (1990, 2004, and 2018). We found that Tehran urban structure has 13 LCZs based on imagery from Landsat 5 and 14 LCZs based on images for La…
Morphological similarities between DBM and an economic geography model of city growth
2009
International audience; An urban microeconomic model of households evolving in a 2Dcellular automata allows to simulate the growth of a metropolitan area whereland is devoted to housing, road network and agricultural/green areas. Thissystem is self-organised: based on individualistic decisions of economic agentswho compete on the land market, the model generates a metropolitan area withhouses, roads, and agriculture. Several simulation are performed. The resultsshow strong similarities with physical Dieletric breackdown models (DBM). Inparticular, phase transitions in the urban morphology occur when a controlparameter reaches critical values. Population density in our model and theelectric …
