Hi Bin, In case it is of interest, here's what I can share: 1. Matlab code to trace isovists; 2. The Matlab code used in CASA paper 69. The code is far from optimized, but it may allow others to work on similar problems.

I found that there is another set of datasets could be useful for the community, i.e. T shape layout used in both Alasdair and Mike papers in EPB. As far as I remember, Sanjay has also a H shape layout, would you be willing to share with us:-). I have a dataset of a fictive urban system used in one of papers, and would be willing to share if it is of interest. Cheers.
