LiDAR, short for Light Detection and Ranging, is a remote sensing method that uses laser light to measure distances and create precise 3D maps of environments. The technology works by emitting laser pulses and measuring the time it takes for them to reflect back from objects. LiDAR is used in applications such as autonomous vehicle navigation, topographic mapping, forestry management, and infrastructure inspection. Its accuracy and ability to operate in various lighting conditions make it a critical tool in both commercial and scientific fields.
