I think I've seen your name in the scipy mailing list. My take on this is to rasterize my vector data with gdal_rasterize (you can have a look at the rasterisation code and see how it works, in case you need to eg buffer your vector data), load it up in python, load my dataset in python, and calculate whatever stats with scipy+numpy. If you look at this thread, you'll find it is very fast: <http://article.gmane.org/gmane.comp.python.scientific.user/19412>. Hope that helps! Jose -- Remote Sensing Unit | Env.
