[Qgis-user] Curvature analysis

[Lester Anderson]

Hello,

A quick query. I can get the max and min curvatures of a surface using
the SAGA algorithms (Terrain analysis - morphometry), but was
wondering how one can derive the most-positive and most-negative
curvature attributes?

The most positive and negative attribute of curvature is supposed to
be good for structural mapping in geoscience.
