LiDAR – Light Detection and Ranging

LiDAR is a remote sensing technology that uses laser pulses to measure distances to the Earth’s surface or objects. By recording the time it takes for the laser to return, LiDAR generates high-resolution three-dimensional maps of terrain, vegetation, and built environments. In geodesy, LiDAR is used for precise topographic mapping, monitoring land deformation, measuring ice sheet and glacier changes, and supporting geospatial modeling and Earth observation applications.
