Laser scanning (also known as LiDAR) is a method of surveying that uses optical remote sensing technology to measure a distant target. It can collect up to 1,000,000 points per second to produce a dense collection of individual measurements known as a “point cloud” with a positional accuracy of 2mm. By taking a distance measurement in every direction, a laser scanner rapidly captures the surface shape of objects, buildings and landscape. The resulting data is a point cloud which is a set of data points in a three-dimensional Cartesian (X,Y,Z) coordinate system!!
