[mapserver-users] network analysis in mapserver

[Seamus Thomas Carroll]

Hi,

I have post GIS installed but I am not currently using it.  I have a road 
network for British Columbia and some other provinces and two sets of 
point data.  I need to be able to find the shortest path along from point 
A (postal code) to point B (hospital data) using an impedance taken from 
the dbf.  For example, the length in metres for an arc or the amount of 
time to travel an arc.  I need the total impedance and a shape file 
representing the path as a result.  Would any of these tools solve this 
problem for me?
