Focus: Lidar

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).

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 the Moon. Now, more than four decades later, Lidar has become a fundamental technology in the geospatial sector. GIM International has compiled a list of nine inspiring and spectacular Lidar projects that show the almost unlimited possibilities... (read more)

Producing High-quality 3D Maps from Lidar

DIPPER, a spin-off company from the University of Twente, provides a breakthrough solution for processing massive amounts of Lidar data accurately and efficiently. It offers comprehensive services related to Lidar data processing and 3D scene modelling. Since the self-developed software is highly automated, one operator working with DIPPER on one laptop can create high-quality 3D maps for 10,000 buildings within just one... (read more)

LIDAR

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. Whether you are interested in latest articles and news on Lidar in general or in specific topics like Lidar Survey and Mobile Lidar, you will find it here!
