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 brand Leica, better known for Leica Cameras, was formed on 2 April 1990 after the merger of several companies.In 2005, the company was acquired by Hexagon AB.Leica was listed on the Swiss stock exchange until the 7 August 2006 which saw the cancellation of all publicly held registered shares in Leica Geosystems Holdings Ltd and delisting of all listed registered shares of a par value of ...

Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, 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.
This lidar scanner may be used to scan buildings, rock formations, etc., to produce a 3D model. The lidar can aim its laser beam in a wide range: its head rotates horizontally, a mirror flips vertically. The laser beam is used to measure the distance to the first object on its path.
A Dutch ISAF sniper team displaying their Accuracy International AWSM.338 Lapua Magnum rifle and VECTOR IV [3] Leica/Vectronix laser rangefinder binoculars. The more powerful models of rangefinders measure distance up to 40 km and are normally installed either on a tripod or directly on a vehicle, ship, jet, helicopter or gun platform.
Leica SL3 Leica T (Typ 701) – In 2014, Leica announced Leica T (Typ 701), the first camera with a body made completely of aluminum. Initially there were two available lenses for the camera, the Leica Summicron-T 23mm f /2 ASPH and the Leica Vario-Elmar-T 18–56 mm f /3.5 –5.6 ASPH. More lenses have been announced for 2015. [15]
A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation's terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources.
