LIDAR which stands for Light Detention And Ranging is a remote sensing method that utilizes pulsed lasers to measure ranges spread within the variable distance of the Earth. These pulses combined with the recorded data of the airborne system generates a 3D information about the Earth’s atmosphere. The data gathered by LIDAR is precise and efficient, collected through its specialized scanner, laser, and a distinct GPS. Usually, helicopters and planes use these techniques. The LIDAR is categorized into two types Topographic and bathymetric used to determine land, seafloors, and riverbeds. The system further allows the scientists to accurately examine both natural and man-made environments with flexibility.
