Lidar, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure variable distances to the Earth. These light pulses—combined with other data recorded by the airborne system—generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. Lidar is widely used for a variety of applications, including high-resolution maps, geology, forestry, environmental research, and urban planning. The technology is particularly renowned for its ability to penetrate dense forest canopy to reach the ground, making it invaluable for topographical mapping in wooded areas. Additionally, lidar technology plays a crucial role in autonomous vehicle navigation systems, where it helps to detect and map surroundings with high accuracy, enabling safe and efficient autonomous driving.
