I have soil samples from boreholes where i have data

changes. i would like to create a weighted average

the DEM, so that i can evaluate potential for
infiltration across a watershed. <br>

You can use v.what.rast to read the DEM value into the
attribute table of your points. Then you can do
whatever calculations you need based on that. <br>

<p>After Moritz's answer, It seems that your question is
a data aggregation problem. If we can see the actual
structure of your data (i.e. <tt><a
href="http://v.info" rel="noreferrer"
target="_blank" moz-do-not-send="true">v.info</a>
-c</tt> or <tt>v.db.select</tt> then more specific
responses might be possible. Best would be a small
subset of the actual data.</p>

Or, if you mean zones of equal height, you can
transform them to vector <br>
polygons and use v.vect.stats on these polygons
and the points. <br>
