[Gwyddion-users] Obtaining 2D slope statistics

[Eric Blair]

Hi all,

I am interested in obtaining the 2D equivalent of the Δa and Δq values
given by the 1D roughness tools. In MetroPro, I am able to create a slope
map and then take the Ra and Rq of this slope map to get the values I need.

Is there a way to get this information in Gwyddion?

Thanks,

Eric

The slope map is available as Integral Transforms → Local Slope. It
calculates the absolute value of the local derivative in each point.
