Hi, Regarding the the smoothing, the description states:
"Flags: [..] -p Preserve original cell values By default original values are smoothed" The first paragraph under "DESCRIPTION" says: "Alternatively, setting the -p flag will preserve the original cell values." Is that not clear enough? If you want then I can add a more prominent statement at the beginning of the help page. The thing is: I originally developed this module for gradiometer data. That data is very noisy and has high local variation. Interpolating that type of data while preserving original measurements will usually result in unsatisfactory output. Also note that the smoothing increases with the interpolation radius. For tiny holes in LiDAR data, try "distance=1" or "2". Of course, LiDAR data probably has different properties and does not need low-pass filtering like gradiometer data. So try "-p" to preserve the original values. An alternative would be to invert the behaviour of the module and assume "-p" by default. I don't work with LiDAR data myself, but I would very interested to know your results!
