[GRASS-user] v.surf.rst vs r.slope.aspect

Dear list,
For a project, I need to derive parameters like slope and aspect from
a high-res DEM from a LiDAR point cloud.
There are several way to do this in GRASS:
- v.surf.rst
- r.slope.aspect
- r.param.scale is a bit special and, I think, has a different purpose.
How do RST and r.slope.aspect compare? I can see (using difference
maps or the profile tool) the results are different, but I'm not too
sure which one to use at the end of the day.
Any thoughts/references on that?
Cheers,
Pierre
