The use of high resolution 3D urban raster and vector
databases in urban climatology is presented. It applies two
different methods to the calculation of continuous sky view
factors (SVF), compares their values and considers their
usefulness and limitations in urban climate studies. It shows
and evaluates the relationship between urban geometry,
quantified by SVF, and intra-urban nocturnal temperature
variations using areal means in the whole urban area of
Szeged, a city located in southeast Hungary. Results from
the vector and raster models shows similar SVF values
(r(2)=0.9827). The usefulness of using areal means in SVFtemperature
relations is confirmed. The vector and the raster
approaches to the derivation of areal means of SVF are
both shown to be powerful tools to obtain a general picture
of the geometrical conditions of an urban environment.
