Light Detection and Ranging (LiDAR) is an optical remote sensing technology that use laser light to examine surface on the earth to find variable distances on the earth. LiDAR is comparable to radar in certain aspects. However, LiDAR uses waves of shorter wavelengths unlike radar, which uses radio waves for measuring targets. The LiDAR technology uses waves typically in the visible, ultraviolet and infrared range. This technology enables direct measurement of 3D structures and underlying terrain with high resolution and high data accuracy. The capability of LiDAR equipments to achieve high resolution makes them superior to other traditional optical instruments used for measuring heights. The LiDAR market can be segmented based on types into airborne and terrestrial LiDAR and based on applications into coastal, forestry, transportation, infrastructure, defense and aerospace, transmission lines and flood mapping among others
