  • Archeologists beam lasers from the sky to unearth ancient settlements hiding in plain sight.

  • LiDAR uses laser pulses to penetrate dense vegetation, revealing human-built structures underneath.

  • State-of-the-art laser technology is transforming archaeology by creating 3D renderings of ruins.

    In recent years, archaeologists have turned to lasers in order to unearth ancient civilizations that were previously invisible.

    A laser technology known as LiDAR — short for light detection and ranging — uses planes to beam thousands of laser pulses from the sky at the ground below, penetrating through thick, deep forest canopy. That provides researchers with three-dimensional maps underneath the vegetation, revealing human-built structures.

    From a Mayan city to complex villages deep in the Brazilian Amazon, here are five previously unknown civilizations that were discovered through state-of-the-art LiDAR technology.

    Using laser pulses, researchers detected a 2,000-year-old Mayan civilization in northern Guatemala with nearly 1,000 archaeological sites.
