Hi Megha,
import your vector map (e.g. with v.in.ogr)
then
g.region vect=yourvectormap #where yourvectormap is the map just
imported
g.region res=X #where X is the resolution of the dem you wish
v.surf.rst input=yourvectormap layer=1 zcolumn=column elev=elevation
#where column is the name of the table column containing elevation data
and elevation is the name of the DEM you need
try to have a look to
g.manual v.surf.rst
for more info on the interpolation procedure...
hope this help
Ivan
