finds and removes all duplicate points from a LAS/LAZ/ASCII file. In the default mode those are xy-duplicate points that have identical x and y coordinates. The first point survives, all subsequent duplicates are removed. It is also possible to keep the lowest points amongst all xy-duplicates via ‘-lowest_z’.

It is also possible to remove only xyz-duplicates points that have all x, y and z coordinates identical via ‘-unique_xyz’. For more details see the README file.
