Building extraction from remote sensing data for parameterising a building typology: A contribution to flood vulnerability assessment

The analysis of flood impacts on buildings in large areas require both a building typology and a method to calculate its physical impacts. This paper focuses on the importance of extraction of building characteristics from remote sensing data in areas where the characterisation of the building structure is lacking. A comprehensive description of a number of building parameters which are necessary for deriving a building typology in the context of flood vulnerability assessment is given. This paper briefly summarises different methods for the extraction of those parameters from remote sensing and GIS analyses. Finally, the application of the extraction of the parameters on one set of data is shown, concluding some advantages of this approach for further analysis of flood damages.
