[GRASSLIST:195] help with shortest distance

GRASS GRASS user

I'm trying to figure out the closest point from another point based on
vector layer. I am planning to have 2 tables one for the roads and
another
for the points. Can v.distance help me with this?

Also can these roads and sites be stored in a postgres database?

yes, v.distance should be the right tool, if you plan on creating road and
point maps. If you only plan on using tables, then you should think about
PostGIS: http://postgis.refractions.net/.

You might also want to look at the experimental GRASS5.1 for much better
vector and database support.
