Spectral filtering as a method of visualising and removing striped artefacts in digital elevation data [PDF]

, 2008
Spectral filtering was compared with traditional mean spatial filters to assess their ability to identify and remove striped artefacts in digital elevation data. The techniques were applied to two datasets: a 100 m contour derived digital elevation model

Single beam bathymetric data modelling techniques for accurate maintenance dredging

Egyptian Journal of Remote Sensing and Space Sciences, 2014
Most ports have dredged channels, berths and anchorages. Such infrastructure suffers from siltation which reduces the depth available for shipping, at which, maintenance dredging is required.
