How does mobile LiDAR work?

4 March 2021
Category: Mobile Mapping

LiDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. A continuously rotating LiDAR system sends thousands of laser pulses every second which collide with the surrounding objects and reflect back creating a 3D representation by measuring the speed of light and the distance covered by it. This helps to determine the vehicle’s position with other surrounding objects.
As well as being a useful component in mobile mapping systems, LiDAR technology will also be key to the development of autonomous vehicles.

Here at KOREC, we’re self-confessed mapping addicts, and we know that maps are so much more than this. So, to celebrate the arrival of KOREC Mapping in May, we asked our colleagues to send […]
