Isovist Analyst is an extension for ArcView, which computes isovists and more than 20 isovist
measures.The extension is available for free for all non-commercial and
non-profit personal use purposes. Please contact me for a copy along with a sentence on the nature of your intended use of the software.
Some noteworthy features of Isovist Analyst include:
Computes isovists and isovist measures based on
ray tracing and the visibility polygon approach, which unlike the
conventional regular grid based approaches, is scale-invariant.
Computes isovists for line, polyline, polygonal
(both convex and nonconvex) obstacles.
Allows an arbitrary sweep angle for the line of
sight (ray interval).
Computes isovists and more than 20 isovists measures
circularity, convexity, clustering coefficient, control and standard
Does not require any other ArcView extension (except IAE-3D versions).
Computes novel measures which allow an objective
identification of the major lines of visibility in a space.

NEWS: A new faster and improved version of Isovist Analyst, which will also work for ArcGIS and potentially other software, is now being
developed. Please check back towards the end of next month for further news.
