[GRASS-user] real distance analysis

[Bödőcs András]

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
