You will probably have to write some custom code, but ...


[5.0/5.3]
Perhaps interpolating to raster (s.surf.rst, s.surf.idw) and then making
a slope map (r.slope.aspect if needed), and then maybe masking with
s.to.rast and r.buffer will give you something to look at, if not
absolute values.


There is probably many other ways as well..
