Word Count : 529
LiDAR remote sensing, which stands for Light Detection and Ranging, is an active remote sensing technique that uses laser light to measure distances between the sensor and the Earth’s surface. Unlike passive sensors that depend on sunlight, LiDAR operates by emitting its own laser pulses and detecting their return after reflection from objects such as vegetation, buildings, or terrain. This capability allows it to generate highly accurate three-dimensional information about the shape and surface characteristics of the Earth. LiDAR has become an essential tool in remote sensing and digital image processing for applications ranging from topographic mapping and forestry to urban planning and disaster management. ________ __________ _______ ________ _______.
