Dear all, I need to compute the frontal area of a set of buildings. I know it depends on a fixed direction and I found this tool isovist analyst that can do it. (http://www.ucl.ac.uk/~ucessan/software/isovist-analyst.htm) I need it to research purpose, but I can not find it (I also wrote to Sanjay Rana). Someone know or use this tool??? Where can I get it?
