A group of archaeologists led by Dr. Damian Evans have discovered a vast network of cities, roads, elaborate water systems and gardens surrounding Angkor Wat that were hidden beneath the thick tropical forest floor. The discovery of the massive cities was made thanks to the use of advanced airborne laser scanning technology called LIDAR, a surveying technology that rapidly fires lasers at the ground from an aircraft. LIDAR is capable of penetrating thick vegetation and foliage in order to map the topography of the ground beneath the forest floor. This allows highly accurate representations of roads, paths, ruins, geological features and cultural heritage sites to be converted into a 3D point cloud model. The 2015 airborne survey of Angkor Wat is the largest archaeological project to ever use LIDAR technology and it covered more than 734 square miles of Cambodian jungle.
