Explanation of used tools. The ‘Sky View Factor’ (SVF) tool computes the ratio between the radiation received/emitted by a surface and the theoretical total hemispheric radiating environment. The sky view factor (SVF) has an important role in the analysis of the urban micro-climate. A new vector-based SVF calculation tool was implemented in a free and open source Geographic Information System named OrbisGIS. Its accuracy and computational performance are compared to the ones of an existing raster based algorithm used in SAGA-GIS. SAGA GIS Brought to you by: oconrad I'm running a sky view factor calculation on a number of DEMs (geoTIFF files), but I wonder what the unit of the radius 2.3.1 Sky View Factor (SVF): SVF is defined by Stewart and Oke (2012) as the ratio between the amount of visible sky from the ground to an unobstructed hemisphere. A Digital Surface Model (DSM) was generated in ArcGIS by incorporating the building heights to the DTM. It was assumed that the buildings The sky view factor (SVF) is a dimension-reduced UCP capturing 3-dimensional form through horizon limitation fractions.
