I was just reading the discussion about an "Open Source ArcPy" today (I am doing a course project writing some modules for different software packages), and mixed in with all the reading and browsing I came across PySAL, which might have some interesting features.
http://pysal.org/ "PySAL is an open source cross-platform library of spatial analysis functions written in Python. It is intended to support the development of high level applications for spatial analysis." They just released version 1.0 yesterday. Has anyone used earlier versions? It looks promising, but I am not up to speed enough to use it myself, yet. Cheers, JP
