Airborne lasers peered through dense trees and ground cover to identify structures from that low-density urban network that have long eluded land-based archaeologists.
Prümers’ team opted to look through the Amazon’s lush cover from above, aiming to find relics of human activity that typically remain hidden even after careful ground surveys. The scientists used a helicopter carrying special equipment to fire laser pulses at the Amazon forest as well as stretches of grassland. Those laser pulses reflect data from the Earth’s surface.
Prümers’ team conducted lidar surveys over six parts of ancient Casarabe territory. The lidar data revealed 26 sites, 11 of them previously unknown.

So amazing what is being discovered with the use of lidar-based 3-D animation technology. Article asks question, whether sites like Cotoca, in the Amazon, in what is today Bolivia, with 'low-density urban sprawl' should be included in what scientists consider a 'city.'
