I have used the
lidR package (https://github.com/Jean-Romain/lidR) to produce a normalized point cloud. I then filter out the points tagged with the overlap bit using:
opt_filter(ctg) <- "-drop_overlap" catalog_retile(ctg)
The resulting point cloud appears to have a directional pattern, where points are present in somewhat uniform strips. It seems the unfiltered point cloud has a similar pattern but much it is much less pronounced. Is this a normal feature of lidar data?
