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?
