Color LiDAR Image (image) University of Central Florida Caption University of Central Florida researchers led a NASA-funded research project in April 2009 that collected the equivalent of 25 years worth of data in four days. Aboard a Cessna 337, LiDAR (Light Detection and Ranging) equipment bounced laser beams to sensors on the ground, penetrating the thick tree canopy and producing images of the ancient settlement and environmental modifications made by the inhabitants of the Maya city of Caracol. This LiDAR image shows the density of terracing in the Caracol epicenter.
