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 consists of emitting millions of infrared light pulses every second from a laser scanner to the target. The coordinates 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 maps after removing the unwanted noises. The entire laser scanning can be completed in just 3 minutes of time with modern ground based terrestrial laser scanning systems having an accuracy of 6 mm.
