[GRASS-user] real distance analysis

[Patton, Eric]

A first stab at this might be r.los:

That's just off the top of my head.

Dear All,

 

I am trying to solve the following problem, maybe does somebody an idea
and can help me.... (thanx in advance)

 

I would like to examine from an exact point that territory, which is
inside an determinated distance from the exact point. BUT I don't want
to use the map projected distance (=Buffer zone), but the datas of a
DEM.

I would like to measure the "really" surface, the climbing etc. For
example  I need the maximum distance "cirlce"  (30km or 30 mph doeas not
matter) around a point, but measured in the "filed"(=DEM) not on the map
(=projected area).

Does somebody have an idea, who can I start with it?

 

Many thanx

Regards

Andras
