Terrestrial LiDAR Surveying

Terrestrial LiDAR is a surveying technology that uses laser pulses to create high-resolution 3D maps and models of the Earth's surface. The term "terrestrial" means that the LiDAR system is operated on the ground, rather than from an airborne platform such as a drone or aircraft.

Terrestrial LiDAR works by emitting laser pulses from a scanner, which then bounce off of the surrounding objects and return to the scanner. The time it takes for the laser to travel to the object and back is measured, and this information is used to calculate the distance between the scanner and the object. By repeating this process many times per second, the scanner is able to create a detailed point cloud of the surrounding environment.

Terrestrial LiDAR has a number of applications, including surveying and mapping of buildings, infrastructure, archaeological sites, and natural features such as mountains and forests. It is also used in civil engineering, construction, and urban planning to accurately measure distances and create detailed 3D models of sites.
