9 Revolutionary Lidar Survey Projects
The history of Lidar goes back to the early 1960s. In 1969, a laser rangefinder and a target mounted on the Apollo-11 spacecraft was used to measure the distance from the Earth to...
Lidar, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics (NOAA, 2016).

Lidar, or Light Detection and Ranging surveying, is a measuring system that uses light. It is widely used in archaeology, forestry, geography, geology, seismology, remote sensing and contour mapping and is spreading to many more geomatics applications. The market for laser scanning is growing strongly as more efficient and cost-effective ways of processing Lidar data create new possibilities in a range of different fields, including construction and engineering, industrial facilities, topographical applications and cultural heritage. GIM International is closely monitoring these developments and will continually keep you updated on the innovations in this ever-changing market through this dedicated Lidar page.
