The Sky View Factor plugin can be used to generate pixel wise sky view factor (SVF) using ground and building digital surface models (DSM). Optionally, vegetation DSMs could also be used. By definition, SVF is the ratio of the radiation received (or emitted) by a planar surface to the radiation emitted (or received) by the entire hemispheric environment (Watson and Johnson 1987).

The DEM of the test area has been processed with GRASS GIS, Whitebox GAT and SAGA GIS. SAGA is a free geographic information system (GIS) having advance spatial data processing capabilities. QGIS Documentation. QGIS has a lot of documentation. All documentation is in English but some documents such as the user guide are also available in other languages.
