From The Atlantic CityLab by Mimi Kirk:
“Earlier this month, archaeologists announced new finds at the site of Angkor in Cambodia—the medieval temple complex that includes the famed Angkor Wat. Researchers have discovered vast networks of cities surrounding the complex that would have been in their heyday in the 12th century. The largest of these cities may even rival the contemporary capital of Phnom Penh in size.
New methods in the field of “space archaeology”—which, just like it sounds, uses space-based technology to pinpoint undiscovered sites—are helping archaeologists make such spectacular finds. Tools such as satellite imagery, as well as sky-based methods like lasers, help show what lurks below the earth’s surface, even in areas with thick vegetation. In the case of Angkor, researchers used lasers attached to helicopters to map the ruins of subterranean infrastructure such as walls, roads, and canals.”
