LiDAR (Light Detection and Ranging), is a method of remote sensing which generates 3D images through the use of laser pulses. Consisting of a laser, a scanner, and a GPS receiver, LiDAR can be used to capture data over a broad area in a short amount of time. Horner & Shifrin has used aerial, mobile and terrestrial LiDAR scans on a variety of projects; from capturing roadway information for a state DOT to asset locating and recording for a short line railroad. With increased accuracy over other methods and ease of data capture, there is no limit to what can be done with LiDAR.
