Motivated by the increasing demand for detailed real city morphology information, a low cost and low tech Digital Elevation Model (DEM) construction methodology is described and applied to neighbourhoods of a Southern European city. An image processing technique is used to derive various morphometric parameters. The analysis focuses on the effect on wind and dispersion due to building layout, building height and shape that are characteristic of a pre-Roman Mediterranean city. It will be argued that f and p parameters together with their vertical distribution comprise the necessary synthetic information about a city morphometry. This research intends to contribute to fill a gap in knowledge about building morphology of Southern European cities. The outcome is of interest for future parameterisations of urban canopy closer to the real spatial configuration of a city within flow and dispersion models.

Abstract
Motivated by the increasing demand for detailed real city morphology information, a low cost and low tech Digital Elevation Model (DEM) construction methodology is described and applied to neighbourhoods of a Southern European city. An image processing technique is used to derive various morphometric parameters. The analysis focuses on the effect on wind and dispersion due to building layout, building height and shape that are characteristic of a pre-Roman Mediterranean city. It will be argued that f and p parameters together with their vertical distribution comprise the necessary synthetic information about a city morphometry. This research intends to contribute to fill a gap in knowledge about building morphology of Southern European cities. The outcome is of interest for future parameterisations of urban canopy closer to the real spatial configuration of a city within flow and dispersion models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
