The derivation of aerodynamic properties of the city surface needs accurate and spatially highly resolved information on the surface form (morphometry). Canyon radiation models, dispersion models, remote sensing approaches and wind tunnel modeling count on 3d models of urban buildings and trees.

Data : ©
For the surrounding of the main urban sites Basel-Sperrstrasse
and Basel-Spalenring, and for the tracer
experiment domain, high resoluted 3d building data is available either
in raster or in vector format (DXF). Data is provided by the
authorities of the city of Basel (GVA
Grundbuch- und Vermessungsamt Basel-Stadt). For the suburban site no
digital data is available at this time.
