The description I have is "a method to quantify the influence of terrain on GPS radiocollar performance by creating a variable called "Available Sky" (Rodgers et al. 1997). Abstract: 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. processing. runalg ('saga:skyviewfactor', dem, maxradius, method, level_inc, ndirs, visible, svf, simple, terrain) 2020-02-28 The Sky View Factor plugin can be used to generate pixel wise sky view factor (SVF) using ground and building digital surface models (DSM).
