Microdrones has unveiled two cases where surveying companies are using lidar integrated into drones to quickly gather data for project analysis and volume measurements.
Adams Surveying, an outfit in Richardson, Texas, is using drone lidar for pre- and post-development projects for site verification.
“We’re using the drone to verify the roads, pads and lots,” said Josh Adams, an unmanned aerial system pilot for Adams Surveying. “We can check the elevations to see how the contractors did versus the engineering plans, to verify that everything was built the way they wanted it to be.”
The first project is at Spradley Farms, an 800-acre undeveloped site where the team will perform a pre-development flight to provide data to Graham Associates to create engineering plans. Microdrones lidar help to meet its goals in surveying open fields where photogrammetry won’t work through canopy or tall grass.
In a Karis project in Crowley, Texas, a 900-acre active project is underway to assess progress and calculate dirt levels.
“Deploying a system from Microdrones over the site really provides us a quick picture of what’s going on,” Adams said. “Using the tools available to us, we can provide survey-grade accuracy to the data we’re providing the client.”
Using drones and lidar in both projects allows surveyors to collect data in the field faster than traditional methods. In a recent flight, a snapshot revealed where the dirt was left at the site and determined how all the pads were created, the side yard swales were cut properly and that the roads are all much lower than the pads by design.
