LiDAR AND ITS APPLICATIONS
1. What is LiDAR?
LiDAR, or Light Detection and Ranging, is a remote sensing technology that uses pulsed laser light to measure distances between a sensor and the Earth’s surface. It creates high-resolution 3D models of ground elevation, even through dense vegetation.
2. How does LiDAR work?
LiDAR systems consist of a laser, a scanner, and a GPS receiver. The laser pulses towards the ground, reflecting off various surfaces, such as trees or buildings. The sensor records the reflected light, and the system calculates distances, using GPS and IMS data, to produce a detailed elevation ...
