NV5 Geospatial and Oklahoma DoT to Showcase Innovative Applications of Aerial Lidar During TRB Annual Meeting

HOLLYWOOD, Fla.NV5 Geospatial, North America’s largest provider of geospatial data services and solutions, will share ground-breaking research on the use of low altitude drone and rotary wing lidar surveys for transportation applications during the 2021 Transportation Research Board (TRB) Annual Meeting, a virtual event taking place in late January. The presentation – “Detailed Comparison of Three Lidar Captures from Drone and Rotary Platforms, and at Different Altitudes on Oklahoma DOT Roadway” – will be part of the session, “The Continued Evolution of UAS for Transportation Design,” scheduled for 4 p.m. on January 28.

 

During the presentation, Mark Meade, P.E., PLS, CP, senior vice president at NV5 Geospatial and Kyle King, PLS, chief of Surveys for the Oklahoma Department of Transportation (DOT), will discuss the performance and accuracy of lidar applications over a two-mile stretch of rural highway. The three applications evaluated were:

 

·         Traditional linear-mode RIEGL 480i sensor flown on a helicopter

·         NV5 Geospatial’s comprehensive low-altitude sensor solution (CLASS), which combines two RIEGL VUX-LRs with nadir and oblique imagery, mounted to a helicopter

·         Single RIEGL VUX-1 flown on a small unmanned aerial systems (sUAS)

 

The project demonstrated that the different, cutting-edge lidar technologies and aerial platforms could deliver extreme horizontal and vertical accuracy for airborne systems flown at altitudes of 250 feet to 600 feet. These configurations also offered results that were similar to those achieved by mobile or terrestrial collection.

 

The results of the Oklahoma DOT research project showed that options exist to provide even greater flexibility for transportation projects, as well as for broader use by airports, railways, utilities and general engineering design.

 

“Helicopters and drones both play an important role in many types of large- and small-scale projects,” Meade noted. “These platforms appeal to many specialized applications where extreme accuracy and resolution are needed, including utilities, infrastructure, asset management, forestry, environmental, and emergency response as well as transportation. The technology aerial platforms can carry is impressive, allowing us to use lidar, multispectral imagery, and long wave infrared (thermal) sensors to derive highly informed answers for our clients.”
