Comment(by hamish):

 > See the r.in.xyz man page for discussion about it.

 the choice raster resolution in r.in.xyz and r.in.lidar has a profound
 effect on the result, and must be chosen wisely. I typically do several
 iterations at different raster resolutions and do some stats on the
 (masked) results to find the optimal one. I have purposely avoided having
 the modules make any attempt to choose that for you since it is such a
 dataset and purpose driven choice, and needs the human operator to
 consider factors beyond the numbers themselves.
