Boots on the Ground or Drones in the Air?

Down to Earth, a surveying reality series, heads into the woods of North Carolina to compare traditional and drone surveying methods on a 15-acre design survey for a development project. In these 4 informative episodes, Allen Geomatics, a land surveying, and consulting firm located in Advance, NC, utilizes a 3 man crew to collect their ground shots and survey the site while Robert Chrismon, PLS, takes a different approach high in the sky with Drone LiDAR.

“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.

These days, many surveying professionals are considering adding drone surveying equipment to their toolbox. In these episodes of Down to Earth, we meet Jeff Allen, owner of Allen Geomatics P.C., a land surveying and consulting firm located in Advance, NC, who is also curious to see if drone surveying methods can enhance his practice.

That’s why he invited Robert Chrismon, PLS, a former surveying co-worker and early adopter of drone surveying equipment, to one of Allen Geomatic’s design surveys for a development project. Together they’ll compare the traditional methods of using a 3 man crew on the ground and Robert’s drone LiDAR system to create a digital map with 1 foot contours as a deliverable.

Episode 2 sees the duo step into the woods to join the Allen Geomatics 3-man crew as they use a Total Station to collect their shots on the ground. Each surveying method faces challenges in the form of thick vegetation, changes in elevation, river embankments and more. “Looking at the distances between the shots taken by the Total Station, it leaves a lot of little undulations and information left to be located,”
Chrismon noted in the field. “That’s what we pick up with the LiDAR.”

The Allen Geomatics office is where Episode 3 begins, as Robert and Jeff compare the results and assess the differences between the traditional and drone surveying data. Both the conventional and drone data.

The series concludes with the fourth episode set in a local restaurant, where Jeff and Robert review the project, workflow, and discuss the changing landscape of surveying technology, all while enjoying a cold beverage.
