[GRASS-user] Compute volume of water using depth vector points.

[Nagesh Bhatkar]

Dear all,

I imported and digitized a hydrographic chart for depth vector points in 
the ocean and
vector lines along the coast enclosing these ocean waters.
I am looking to  the interpolate these randomly digitized depth points
over a grid of any resolution and then later compute the volume of the 
water in the ocean
channel  between two land masses.
Which modules of GRASS GIS would help me accomplish the above two tasks.

Regards
