Urban morphology retrieval bymeansofremote sensing for the modelling of atmospheric dispersion and micro-meteorology

This paper describes a prototype of an urban morphological database for micro-meteorological and dispersion modelling. The database relies on digital maps and satellite observations including optical images, SAR interferometry and digital maps. The structure of the database is presented and methods to produce thematic layers in an affordable way are shown. A fine resolution model was compiled regarding urban morphological features that cover a rectangular area of 6 × 3 km
²
in central Paris. The model contains selected thematic layer types on water, parks, trees, streets, buildings, average height of blocks, digital elevation model of the terrain, coherence and the urban heat fluxes. This study is part of an EU-funded project ¿Megacities: Emissions, urban, regional and Global Atmospheric POLlution and climate effects, and Integrated tools for assessment and mitigation¿ -MEGAPOLI.
