grass, xgrass gis, routing

[Malcolm Williamson]

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!
