[GRASSLIST:10770] Re: How to calculate maximum & minimum elevation across a raster?

[Ian MacMillan]

Michael, I am sure you have already thought of this, but have you tried 
to use r.profile?  This would work if you know the two endpoints.  If 
you don't know the endpoints, but are trying to calculate the general 
case between a point and an area, doesn't r.sun deal with this somehow? 
  I am not superfamiliar with it, but that would be where I would start.

G'luck,
Ian

What happens if a big asteroid hits Earth? Judging from realistic 
simulations involving a sledge hammer and a common laboratory frog, we 
can assume it will be pretty bad.
