Kevin, There is plenty of visibility releted stuff done at UCL London. A large group of people are working under loose frame work of Space Syntax (http://www.spacesyntax.org/). It might be a bit dogmatic sometime refering only to early work of Hiller and Hanson, but there are interesting and inspiring people around also. Unfortunatelly much of this is not done for MI. (Please follow the Place Syntax Tools at http://www.arch.kth.se/sad/index_subpages/ps_factsheet.htm to find out more the only one I know of). Personally I favour isovists approach over lines of sight. None of it is at MI platform, but Sanjay Rana has made Isovist Analyst for ESRI platform that can be found at: http://www.ucl.ac.uk/~ucessan/software/isovist-analyst.htm <http://www.ucl.ac.uk/~ucessan/software/isovist-analyst.htm> Alasdair Turner (http://www.vr.ucl.ac.uk/people/alasdair/ <http://www.vr.ucl.ac.uk/people/alasdair/> ) have made a standalone Depthmap software and also some nice multi-agent thingies Theoretical background is also discussed Centre of Advanced Spatial Analysis workpaper series (http://www.casa.ucl.ac.uk/publications/full_list.htm) by Mike Batty and others. I hope this helps you out.

Hi list, I am trying to work out the lines of sight from a given point. Basically I have view point situated on a street network and I am trying to work out the amount of shop frontage can be seen from a given point. I can do this in an approximate way by drawing straight lines from my view point and lining them up with the corners of obstructing buildings - then I can roughly see how much shop frontage I can see (in between the obstructing ones). While this method has given me an approximate indication I was wondering if anyone had come across a more methodological way of achieving this.
