Together, they will compare traditional methods of using a 3-man ground crew and Robert’s LiDAR drone system to create a digital map with 1 foot outlines as the deliverable.

Each surveying method faces challenges in the form of thick vegetation, elevation changes, river embankments and more. “Looking at the distances between the shots taken by the Total Station, it leaves a lot of little ripples and information to locate”,
Chrismon noted on the ground. “This is what we find with LiDAR. “
