[GRASS-user] Creating Geological Cross Sections

[Travis Kirstine]

I currently have several raster layer representing overlapping
geological surfaces.  Each layer has both top of surface elevation and
thickness.  I would like to create a cross section like this one based
on a vector line:

Is this possible, any hints?

Thanks for your time
