I have a PostGIS database of geographic points which I would like to
find shortest paths between.
a) I have access to road network data. I've heard the new GRASS can
be used to do network analysis. anyone heard if it would be promising
in combination with postGIS, or could suggest another package?
b) as an alternative, can anyone suggest or point to an efficient
approach for computing the shortest path between two points which does
not go through, say, water polygons?
thanks in advance,
