To whome it may concern:
I am looking for information regarding a routing package for the
grass gis package. I have the grass v4.1.5, compiled for the linux
system, and I need a transportation routing package to go with it. I am
trying to use the grass software set with satellite imagery, tigerline
files, and a database product to overlay the address ranges onto the
road features of the tiger line files.
I would like to be able to find the shortest route between to
addresses, and the best route based on traffic volumes weighted against
time of day constraints. Any help in finding a routing package that will
integrate to the grass software set, and the postgress95 database system
would be greatly appreciated. I am running a linux system, and not a
sun, so some of the features of the grass distribution may not work yet.
Any and all help would be appreciated.
Any one that can help can reach me at the following e-mail address:

Bruce,
To the best of my knowledge, no one has developed a vector-based GRASS
program for network analysis. Network analysis in raster format is
probably not desireable, but if you are truly interested, check out:
Tomlin, Dana C. _Geographic_Information_Systems_and_Cartographic_Modeling_.
1990. Prentice-Hall, Englewood Cliffs, NJ.
PS. If this was readily done in GRASS, _everyone_ would be using it!
