‘Lost’ Roads of Ancient Rome Discovered With 3D Laser Scanners
19th October 2016
Laser scans of Britain’s terrain may reveal weathered Roman roads that have been hidden for centuries across the countryside of northern England.
Over the past 18 years, the U.K.’s Environment Agency has used a technology called lidar to collect data for more than 72 percent of England’s surface. This remote sensing technique bounces laser light beams off the ground to make 3D terrain maps that can peer below vegetation and reveal the contours of every ditch and boulder below.
