LiDAR helps transform the field of archaeology

The imaging abilities of LiDAR are dramatically changing the way archaeologists and anthropologists do their jobs. The technology can produce high-quality maps of terrains faster, and with more accuracy, than older tools. Being able to map areas more quickly means researchers can spend more time analyzing the terrain and using it to understand ancient peoples. "Each point that we have has a plus/minus range of 2.5cm -- roughly the size of a Rubik's Cube. So we can now use it to investigate not only ancient cities but the broader landscape, and connections between these features on the landscape," archaeologist Chris Fisher said.
