US: Researchers believe they may finally have uncovered the lost ”White City of gold” in Honduras using hi-tech scanners that let aircraft ”see” through dense forest. Researchers from the University of Houston and the National Center for Airborne Laser Mapping (NCALM) flew over the Mosquitia region in a small plane shooting billions of laser pulses at the ground to create a 3D digital map of the topology beneath the jungle canopy.
Compiling their data, the analysts revealed what appears to be man-made elevation changes that are thought to show a forgotten city plaza dotted with pyramids reclaimed by the jungle.
Over the course of a week, the NCALM and University of Houston engineers flew over 60 square miles of forest in their dual-engine Cessna planes. LiDAR’s computer-generated images allowed researchers to ”see” through the forest canopy to the ground surface, revealing any evidence of ancient settlements or human-engineered landscapes.
This was one of the first times that laser mapping, specifically LiDAR had been used to locate ancient ruins.
