UAV LiDAR Fast-Track’s Levee Damage Assessment After Hurricane Harvey

Editor’s Note: LiDAR Magazine recently published an article highlighting how LiDAR was used to aid the analysis of the levee system following Hurricane Harvey in Houston. Precision Aerial used the RIEGL VUX-1 LiDAR sensor and Sony A6000 36.4-megapixel camera to collect critical information for repairing and analyzing this vital levee system. This levee, built in 1913, provides flood control in the Houston area. Without it working to capacity many parts of the community would be flooded during heavy rain seasons or hurricanes.

Precision Aerial used RIEGL’s VUX-1 LiDAR sensor to get data in a fraction of the time necessary with previous methods.


In 2019, Precision Aerial performed three levee surveys utilizing their UAV LiDAR system. Using LiDAR, they were able to gather all the necessary data in just over one week. Traditional techniques would have required months of work and a survey crew. This updated process provided a viable means of delivering critical, accurate data from difficult-to-reach areas in a cost effective manner and in short period of time.
