In the coming age of the autonomous vehicle, fast and accurate LiDAR surveying will be increasingly important, explains Valdis Vanags. The game-changing introduction of autonomous vehicles relies not only on intelligent traffic systems but well maintained roads to help computer-guided systems navigate using road markings. Laser scanning technology, too, is a game changer when it comes to planning and executing many civil engineering projects, including transport network upgrades and smart city initiatives.
