Determining the rate of erosion and lichen spread on Samaipata rock by comparing 3D laser scan results from two different surveying epochs

Abstract

The paper describes the possibility of using 3D laser scans from two different surveying epochs for structural health monitoring. It uses the results of two particular projects-the 2006 3D laser scanning of Samiapata rock by the University of Arkansas and the 2016 3D laser scanning by the Laboratory of 3D Laser Scanning at Wrocław University of Science and Technology-and discusses the methods, results, and limitations of comparing them.
