Hi Micha,
I have soil samples from boreholes where i have data points at every meter
interval and where soil type changes. i would like to create a weighted
average of soil property for lets say the first 1 m below the DEM, so that
i can evaluate potential for infiltration across a watershed.

You will most likely have to convert the points to raster. But before
that, can you explain what you mean by "located for 10 m from DEM", "10
to 20".
Or, if you mean zones of equal height, you can transform them to vector
polygons and use v.vect.stats on

Hi
Hi
I would like to use mapcalc with types of input a DEM (raster) and xyz
property (vector). basically, I would like to do a weighted average of
data points located for 10 m from DEM, then 10 to 20 etc.

Dear all,
Since there is a lot of expertise on the ML in hydrology and LiDAR, I was
wondering if someone is aware of a GRASS approach for identifying and carving
Culverts (as well as removing bridges) in LiDAR DEMs.
Here some non-GRASS examples of what has been done earlier:
