Hi Francois,
I think you can use directly v.vol.rst directly on a 3D vector
(v.in.ascii with -z flag) to interpolate the points and obtain the 3D
raster.

Hi,
I am trying to build a Raster out of a vector file (points) which
consists of soil properties at a given elevation and coordinates XY.
I have attached an example file that I have extracted from the main
table which contains all XY Z and properties. I am proceeding with
building a raster for each elevation as I think that grass has issues
with using 3D vectors with stacked data (vertically) from Borehole
logs (that’s a different issue). Then I will combine the 2D raster
into one 3D raster.
I am reasonably new to Grass, and so far I have been able to combine
multiple DEM together, add attributes to table from different Rasters
(DEM, Bedrock surface), but I am unable to create a raster from a
simple table, or at least see the raster. In Grass it shows that the
raster is in the Tree, but I am unable to show the colors etc. I am
not sure what I am doing incorrectly. I have tried several methods
such as v.in.ascii, etc.
As I have been trying this for many days, I am sending this email to
the mailing list.
My ultimate goal is to build a 3D raster of soil properties over a
large area (40 km x 40 km x 200 m depth).
Thanks for your help!
F.
