Power spectrum of DEMs

Dear community,
is there a way to calculate the power spectrum of a 2D grid/1D profile in order to get an overview of the wavelength Distribution, e.g. in the topography?
I am aware of the Radially Averaged Power Spectrum Option in MAGMAP for depthtobasement estimates but this does not help here.
Cheers,
Martin

Hi @MartinVögele there are two other power spectrum calculations:
 From the 1DFFT menu click Power Spectrum to calculate the log power spectrum of a channel from a database.
 From MAGMAP, below the Radial Average Power Spectrum tool there is a 2D Power Spectrum option.
