Visibility graph analysis(Redirected from Visibility analysis)
In architecture, visibility graph analysis (VGA) is a method of analysing the inter-visibility connections within buildings or urban networks. Visibility graph analysis was developed from the architectural theory of space syntax by Turner et al. (2001), and is applied through construction of a visibility graph within the open space of a plan.
Visibility graph analysis was firstly implemented in Turner's Depthmap software and is now widely used by both academics and practitioners through the open source and multi-platform depthmapX developed by Tasos Varoudis.
