Abstract
The representation and visualization of more or less detailed 3-D urban scenes can be done using different techniques, from those more conventional (for example, photogrammetry) to the most recent ones (for example, laser scanning). However, the use and application of this kind of data for the study of urban environment quality (UEQ) remains unsettled; indeed, the correct definition of indicators related to this field is highly necessary for the analysis and planning of urban developments. Moreover, the state of the art of 3-D Geographical Information Systems (GIS) available in the market still lacks the possibility of applying complex spatial analysis operations to the urban scale. Hence, the applied methodology is directly related to the extraction of these indicators, which are calculated according to the available 2-D and 3-D geo-referenced urban data. The work here presented is part of a larger jointly project between many researchers, experts and end-users around Europe which integrates cross-disciplinary competences, like remote sensing, GIS, image processing, energy, environment, architecture and urban design. In order to extract and validate the use of the proposed indicators, some case studies have been applied to several pilot zones of the cities of Geneva, Lausanne and Lisbon and are here presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
