If by hard you mean no smoothing, extrapolation, etc, just what the data
points say, you might try 'v.out.ascii | r.in.xyz method=n' after setting
up an appropriate grid size with g.region.

maybe a r.neighbors run could smooth things over.


I don't know much about using v.kernel beyond the basics, so no advice
there.
