Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Atmospheric lidar is a class of instruments that uses laser light to study atmospheric properties from the ground up to the top of the atmosphere. Such instruments have been used to study, among other, atmospheric gases, aerosols, clouds, and temperature.
Laser based lidar (LIght raDAR) technology applications in geology, seismology, remote sensing and atmospheric physics. Three-dimensional structural modifications and writing inside technological materials. [1] Lasers have been used aboard spacecraft such as in the Cassini-Huygens mission. [2]
IBM Research will carry out a pilot program in Britain with Cera Care to explore the utility of LiDAR sensors for elderly care. IBM Research will carry out a pilot program in Britain with Cera ...
How Cars Use Lidar to Map for Hands-Free Driving BMW For a hands-free driving system to keep a vehicle safely in its lane, the software first needs to know where that lane is and some information ...
UC Merced Land Use Dataset These images were manually extracted from large images from the USGS National Map Urban Area Imagery collection for various urban areas around the US. This is a 21 class land use image dataset meant for research purposes. There are 100 images for each class. 2,100 Image chips of 256x256, 30 cm (1 foot) GSD
LiDAR system emits pulsed and continuous-wave lasers to acquire 3-D information. The laser scanner is the main component of LiDAR. Lasers with a wavelength of 550-600 nm are used on a ground-based system (handheld laser scanning and terrestrial laser scanning), whereas airborne systems use lasers with 1000-1600 nm wavelength.

The images are then taken and processed by an archaeologist who specializes in satellite remote sensing in order to find any subtle anomalies on the Earth's surface. Landscape features such as soil, vegetation, geology, and man-made structures of possible cultural interest have specific signatures that the multi-spectral satellites can help to ...
