<p>Hi Francois,</p>
<p>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.<br>
</p>
<p>Cheers,<br>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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. </p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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. </p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.</p>
<p class="MsoNormal">As I have been trying this for many days, I
am sending this email to the mailing list. </p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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).</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your help!</p>
