[GRASS-user] real distance analysis

[Andrew Schroeder - Charone Concepts Ltd.]

If I'm not mistaken, you mean the distance as it would be measured on the
ground, rather than in plan.  In mountainous areas, 1km in plan is a lot
different from 1km on the ground.  I've wondered how to approach this as
well, and would like to hear what others think.

r.surf.area, r.volume?
