I'm forwarding this on from the postgis list.  Is there are faster way of
determining such a matrix, short of doing n * m  shortest path queries from
n origins and m destinations?

Thanks,

Francis Markham

hello all, any of you know any library or know of any script for analysis of
transmission or some script to create matrices of origins and destinations,
and I can not work with arcgis, only free libraries, any suggestions thank
you for your answers and opinions. :)
