Abstract

The access and quality of digital spatial data covering urban areas have increased substantially in recent decades. As a result new methods using different kinds of spatial data within the field of urban climatology has been developed. This paper illustrates how digital data could be used to analyze spatial variations of the urban climate using a detailed Digital Elevation Model (DEM). Parameters such as the Sky View Factor (SVF) and insolation properties are modeled using municipality data covering the central areas of the city of Göteborg in Sweden. Model validation is conducted using hemispheric photographs and meteorological measurements.
