LiDAR—short for Light Detection and Ranging—is a cutting-edge remote sensing technique that uses pulses of laser light to measure distances with exceptional precision. By emitting thousands of laser pulses each second and analyzing the time it takes for the reflected light to return, a LiDAR sensor creates a highly accurate, three-dimensional representation of the surrounding environment. This technology not only captures surface elevation data but can also penetrate dense vegetation to reveal the true terrain underneath, making it an invaluable tool for industries ranging from surveying and forestry to archaeology and infrastructure inspection.
Mounted on drones (often referred to as LiDAR UAVs), LiDAR cameras and sensors deliver elevation maps and point cloud datasets at remarkable speed and accuracy. When compared to traditional photogrammetry—which relies on overlapping images and can be influenced by lighting conditions—LiDAR provides more direct and consistent measurements. The result is cleaner elevation models, detailed structural insights, and richer datasets that empower professionals to make confident, informed decisions across a wide range of applications.
