Tool Destriping

Destriping filter removes straight parallel stripes in raster data. It uses two low-pass filters elongated in the stripes direction; the first one is 1 pixel unit wide while the second one is wide as the striping wavelength. Their difference is the striping error which is removed from the original data to obtain the destriped DEM. This method is equivalent to that proposed by Oimoen (2000).
