[GRASS-user] thresholds for plan and profile curvature

[Andruit at gmx.de]

Hello,
I calculated profile_curvature and plan_curvature from a 10m DEM using r.slope.aspect...

Now I would like to classify the calculated values. 

Are there any thresholds for concave, straight, convex???

I was looking for thresholds  on the Intenet, but I haven´t found any.

Maybe you have any suggestions.

Thanx

Andreas
