LiDAR Sensors

Capture high quality, accurate elevation data

Light Detection and Ranging (LiDAR) sensors use light energy, emitted from a laser, to scan the ground and measure variable distances. The end result is a rich set of elevation data that can be used to produce high-resolution maps and 3D models of natural and man-made objects.

LiDAR technology dates back to the 1960s, where it was first used by engineers and surveyors to produce high-fidelity topographical maps that included roads, streams and other important landscape features.

Compared to other aerial survey methods, drone-based LiDAR collection yields the highest fidelity data. The point cloud generated from drone-based LiDAR can yield 100–500 points per square meter at a vertical elevation accuracy of 2–3 centimeters.
