Spatial aliasing

An omnipresent theme in geophysical surveying is that we never have enough spatial coverage. In my book GEE, a theme is that we cope with insufficient data not via autocorrelation calculation but via prediction-error filter (PEF) estimation. Multidimensional PEFs are also a natural way to handle non stationarity. No doubt, we could return to the PEF approach for dealing with scattering too.
