Archaeology is being revolutionized by remote-scanning techniques that use lasers to detect otherwise invisible ground features. The technology digitally extracts vegetation for a clean image of the earth’s surface. Archaeologists in Germany have already discovered thousands of new sites.
In the coming years, looking at sites from above could also become the standard method for investigating the past because the costs continue to go down. Just a few years ago, researchers still had to board planes to take such images, but now unmanned drones are being used to perform jobs that can be handled from low altitudes. The combination of LIDAR technology and computer-supported image analysis is providing fantastic opportunities, according toPosluschny.
