What Is LIDAR?
Lidar (also called LIDAR, LiDAR, and LADAR) is a surveying method that measures distance to a target by illuminating that target with a laser light.
The name lidar, sometimes considered an acronym of Light Detection And Ranging (sometimes Light Imaging, Detection, And Ranging), was originally a portmanteau of light and radar.
Lidar is popularly used to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. Lidar sometimes is called laser scanning and 3D scanning, with terrestrial, airborne, and mobile applications.
And The Benefits ?
Time frame is relatively fast
Accurate (vertical accuracy up to 20cm)
Eliminates data manipulation
Minimizes contact with people who potentially have social impacts,
Capable to reach areas that are geographically difficult to access.
The data management is easier and more secure since it is stored in a digital format.
