[GRASSLIST:5399] s.vol.rst

[Christoph Hoesli]

hi

I've interpolated precipitation data with r.vol.rst.
what is the advantage of this volumetric interpolation over a 2D
interpolation
(e.g. s.surf.rst) for precipitation data? s.vol.rst does not consider the
orography, does it? Is there a benefit using s.vol.rst instead of s.surf.rst
if I only need a 2D raster output?

thanks
christoph
