Charting Hazardous Terrain With Drone LiDAR

The McGehee Engineering Team Keeps Safe and Uses LP360 to Create High-End Deliverables

In this 3-minute Case Study video, see how the UAV Surveying Team at McGehee Engineering Corp. is using drone LiDAR surveying equipment from GeoCue to conduct aerial surveys over 300 acres of cliffs and dense forest.

Drone LiDAR surveying allows the survey team to conduct more surveys and provide data to their customer quickly and more efficiently.  What normally might take weeks with traditional surveying methods, they anticipate completing in a das. See how in this 3-minute case study video:

McGehee Engineering Corp., incorporated in 1989, found its niche in the coal mining industry in Alabama and has since grown its business into a multi-disciplined consulting firm providing mining, environmental, civil, geotechnical, analytical, and specialized expertise to a broad range of clients.

Keeping up with the times means keeping up with technology, and Jordan McGehee, a partner in the firm, has become an expert in aerial mapping and surveying.  Especially on a particularly challenging project for a coal mining customer who needs to build a large conveyor belt on the side of a steep bluff to transport material down the cliff.

The sheer size, extreme terrain, and extensive vegetation would take months to survey using traditional methods to create the topography of the bluffs and forests. That’s why McGehee Engineering utilized TrueView drone LiDAR technology from GeoCue to quickly survey the project, safely collect the data, and more accurately provide the contours and surface designs needed to engineer the coal conveyor belt.

Stephen Blankenship, the Environmental Engineering Department Manager at McGehee helps with project management. To get started, Jordan and Stephen reviewed the project site and set up the TrueView 515 for action.   

One of the main difficulties is the terrain and the thick canopy in the area. Also, the safest take-off zone for the survey, is far across the river, adding to the complexity of the flight.  Through proper planning, safety protocols, observation, and some beautiful, spring-Alabama weather, everything went according to plan. In a day’s worth of flights, the team covered 300 acres of challenging terrain and headed back to the office to process the data.

Using LP360 Lidar and Point Cloud processing software, Jordan will create a complete orthophoto, a digital contour mapping, and the topography of the site. This will enable the client to establish the necessary design work for the conveyor belt and the barge loadout facility.

The final results? McGehee’s Clients couldn’t be happier.

With the TrueView 515 3D Sensor and LP360 software, McGehee Engineering delivers unmatched precision and efficiency, ensuring success for every project.
