LiDAR, also known as Light Detection and Ranging has become an established method for collecting very dense and accurate elevation values. This active remote sensing technique is similar to radar but uses light pulses instead of radio waves. LiDAR data is typically collected from planes and produces a rapid collection of points i.e. more than 70,000 per sec, over a large collection area. Collection of elevation data using LiDAR has several advantages from recent advancement in GPS and IMU technology.
