By deviation
Not Lite
By deviation routine classifies points based on the Deviation attribute. The deviation is usually derived from the Riegl Extra Byte attribute Pulse shape deviation. A small deviation value indicates a normal shape return pulse. A big deviation value indicates an abnormal shape return pulse which may be caused by noise. Thus, the routine is useful for eliminating potential noisy points from more reliable points.
