Laser-mapping LiDAR revolutionizes archaeology


Not specifically Egyptology but of general archaeological interest.

"This is it—the paradigm shift," archaeologist Chris Fisher told Ars. "Just like the advent of radiocarbon dating, LiDAR will have the same impact."

LiDAR, or "light detection and ranging," acts as a sort of radar with light, painting the target area with lasers and recording the time it takes to reflect back to the instruments.

An archaeologist specializing in Western Mexico, Fisher studies the way environments affect and change cultures. LiDAR has helped him repaint the picture of ancient Mexico, bringing the little-known Purepecha empire a lot more historical prominence. . . .

Last year, LiDAR enabled Fisher to create a full-fledged picture of the important Mesoamerican capital in greater detail. This included the discovery of several pyramids, ceremonial complexes and thousands of residences and other buildings that no one knew existed in the city.
