Morris P. Hebert, Inc. uses drone LiDAR to analyse a Marsh restoration project in Southern Louisiana by Microdrones.com
Down to Earth, a surveying reality series, journeys into the remote wilderness of the Southern Louisiana wetlands, to follow surveying and engineering firm, Morris P. Hebert, Inc. (MPH,) as they use drone surveying equipment from Microdrones to verify fill levels in a marsh restoration project.
The next three new episodes are set to premiere Wednesday, May 26, 2021. Viewers can register to watch at either 9am ET or 6pm ET here.
Down to Earth is a reality series that shows how real surveyors collect data and turn it into real deliverables, despite challenging terrain, rough weather, and hidden dangers.
For this project, we learn that coastal Louisiana faces some of the highest land loss rates in the world due to both natural and manmade factors. To help prevent further land erosion, extensive coastal protection and restoration plans are underway. Part of these efforts include marsh creation projects, to quickly restore wetlands, expand habitats and help prevent future land loss.
MPH was tasked with surveying over 200 acres of a marsh restoration project to analyse pre and post conditions. They’ll need to determine if quantities of fill material meet the design specifications that were set forth for the restoration. This three-part series of Down to Earth follows the MPH team as they deploy drone LiDAR and the use of an airboat to conduct the survey with minimal environmental disturbance.
The first episode introduces the MPH Surveying team of Dakota Dagenhardt, an Environmental Regulatory Specialist and Kiley Cressionie, a Remote Sensing Tech, as they give an overview of the project and discuss some of the challenges they face.
In Episode 2 Dagenhardt and Cressionie utilize the assistance of an airboat to help keep tabs on the drone LiDAR system as it flies over the extensive marsh.
“Our survey area extends to over 1,000 meters away from our launch site,” Cressionie explains. “While we can maintain line of sight, it’s better to have a visual observer in closer proximity to the drone and in constant communication with the pilot. The airboat gets us out to the edge of our survey area with relatively little environmental disruption.”
The final episode in the series is set in the Houma, Louisiana offices of MPH, where their R&D and Training Coordinator, Lee Drennan, processes and visualises the LiDAR data to create a point cloud and orthophoto of the marsh restoration project.
“We’ve used the mdLiDAR3000 for landfills, construction projects, and marsh restoration areas,” Drennan said, “because the LiDAR really lends itself to anything involving volume calculation. Not only can we do the project faster and more efficiently, but we can provide a better product, since the LiDAR point cloud is so dense.”
