What Is The Vertical Accuracy Of Your LIDAR Data?
Created: 26 July 2018 Updated: 14 October 2021
Our specifications require the absolute height error to be less than ±15 cm. This is the root mean squared error or RMSE. It quantifies the error or difference between the Ground Truth Survey and the LIDAR data. We expect the relative height error (random error) to be no more than ±5 cm.
To find out the Ground Truth result of a particular survey please see our LIDAR Capture Programme dashboard.
