[GRASS-user] GRASS raster curvature analysis type

[Djordje Spasic]

Hello,

I would like to know whether raster curvature analysis in GRASS is Gaussianor Mean curvature analysis?
https://en.wikipedia.org/wiki/Gaussian_curvature
https://en.wikipedia.org/wiki/Mean_curvature

This GRASS 7.2 manuals page mentions that raster curvature analysis can be conducted in direction of steepest slope and in the direction of the contour tangent, therefor distinguishing two curvature options: profile and tangential.

Still are these two Gaussian or Mean curvatures?

Thank you for the reply.

Kind regards,
Djordje Spasic
