520 _a Abstract Light Detection and Ranging (LiDAR) data has proved to be useful in recent years since it gives information, such as item height and attributes, and statistics over large regions, and it all becomes available by capturing the intensity of backscattered pulses in addition to 3D coordinates. A LiDAR may generate a 2D angle image and a 3D picture containing angle/range information. It can directly measure range in each pixel since it controls when light is emitted, allowing it to calculate range based on the Time of Flight (ToF) to and from the object in a particular pixel. If there is enough signal, a 3D picture can also have grayscale and color. Coherent LiDAR can detect velocity quite precisely. A brief introduction of airborne laser scanning technology, also known as LiDAR, and research findings on its application in forest assessment and monitoring are discussed in this paper.
_b Introduction Light Detection and Ranging (LiDAR) employs electromagnetic (EM) pulses of optical and infrared wavelengths. It is an active sensor which emits an EM pulse and receives the signal that bounces back. It is similar to microwave radar, but with a much shorter wavelength. That means it has far greater angular resolution than radar, but unable to see through fog or clouds. It is similar to passive Electro-Optical (EO) sensors in wavelengths, except that it creates its own radiation rather than utilizing existing radiation and has several sensing modes due to control over the scene illumination (De Raedt et al., 2009, p. 1/10). Definition of Key Terms LiDAR LiDAR employs lasers to determine the heights of objects, such as the ground, woods, and even buildings. It resembles a radar, which uses radio waves to map things, or a Keywords LiDAR, 3D, Time of Flight (ToF), Pulsed Time of Flight, Electromagnetic pulse
