Overview

This accuracy report describes the relationship between the ground control points and the LiDAR data. Each GCP is placed on the LiDAR data and a Z deviation is determined. The RMS takes into account the roughness of the LiDAR data to give a higher weight to GCP points on smoother surfaces.
