Using Laser Signals via aerial LIDAR to Map an Ancient Civilization in a Matter of Days, Surpassing Decades of On-the-Ground Mapping : Caracol : Belize : Archaeology by Chase & Chase

Laser signals via aerial LIDAR (light detection and ranging) permit a twin-engine aircraft to map ancient Caracol in Belize in Central America in a matter of days, surpassing mapping results obtained by on-the-ground mapping over two and a half decades by the archaeological husband-and-wife team of Arlen F. Chase and Diane Z. Chase.
