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.
Interpolation:
v.surf.rst
v.surf.idw
r.surf.nnbathy (Add-On)
etc
volume calculation:
r.volume
