UAV/drone surveying

The Water Research Laboratory has developed the expertise, qualifications and equipment range to now provide a professional UAV monitoring service for a wide range of engineering and scientific applications. Our fleet of UAVs includes a fixed wing SenseFly eBee RTK for projects requiring survey grade elevation data, a Vulcan Octocopter with an integrated LiDAR unit for high density surveying and a smaller DJI Phantom 3 Quadcopter with HD video camera suitable for visual aerial monitoring and inspections. Combined with our suite of RTK-GPS equipment, our UAVs provide an innovative and cost effective method to collect high quality survey grade elevation data, high resolution ortho-rectified aerial photography and high definition aerial video data, even in remote areas. 

All UAV deployments undertaken by WRL are carried out by one of our Civil Aviation Safety Authority (CASA) approved pilots, who ensures that every UAV survey is conducted in a safe manner that complies with professional flight regulations. Within Australia, WRL have pioneered the use of UAVs for monitoring in the coastal zone, and have now published summary papers to provide an overview and demonstrate the accuracy achieved with the UAV survey methods. We have undertaken numerous scientific surveys that have included analysis of beach erosion, high resolution mapping of breakwater and revetment structures, monitoring of emergency coastal protection works, estuarine vegetation mapping and wetland monitoring. These applied projects have proven the effective use of UAVs as a cost-effective survey tool that provides an alternative method of collecting aerial photography, videography and geospatial data.


 

Specialist expertise for analysis

In addition to providing general surveying and monitoring services, WRL provides a turn-key solution by leveraging our core technical expertise to interpret recorded data. WRL’s engineers and scientists have the skill set and track record to analyse survey data for a wide range of coastal, environmental and hydraulic engineering requirements.
