LiDAR, which stands for Light Detection and Ranging, is an advanced remote sensing technique that uses laser light to measure distances between the sensor and the target surface. Unlike traditional optical or radar systems, LiDAR generates highly accurate three-dimensional data of the Earth's surface and objects by emitting laser pulses and recording the time it takes for the pulses to return after hitting a target. This method allows for precise elevation measurements, vegetation mapping, infrastructure monitoring, and detailed topographical modeling. LiDAR is widely used in applications such as forestry, urban planning, archaeology, disaster management, and autonomous navigation due to its high resolution and capability _______ _______ ______ ____ _____ _____ ___ _________ ________ ______ ___.
