This algorithm has been included in a larger software package being developed with Simon M. Mudd at the University of Edinburgh which should be available at a future date. +

Typically applied to high resolution (1 m LiDAR) gridded topographic datasets. Could pheasably be applied to other resolutions where the scale of noise is similar to the resolution of the topographic data. +
Filtered DEM: A new, filtered DEM in *.flt binary format.
Noise: A *.flt binary format grid of the filtered noise. +
Uses a non-local means filter image processing technique to perform filtering/smoothing of a DEM. +

Smoothes noise in a DEM by finding the mean value of neighbouring cells and assigning it to the central cell. This approach deals well with non-gaussian distributed noise. +
