3D laser scanning technology or popularly known as LIDAR is a Light Detection and Ranging Technology that helps to create an accurate 3D representation of any given earth structure such as buildings, dams, roads, forest, etc. The technology is capable of emitting millions of infrared light pulses every second from a laser scanner to the target and recording the time of travel. Knowing the speed of pulse and time of travel, the location of target coordinates can be found, which finally results in “point cloud” consisting of millions of data points with X, Y, Z coordinates. This data can then be used to prepare the 3D - map of any given structure after removing the unwanted noises. The entire scanning can be completed in just three minutes of time with modern ground based terrestrial laser scanning systems having an accuracy of 6mm.
