“A journalist and photographer from the newspaper accompanied the ‘Indiana Jones-style’ expedition, led by a French-born archaeologist, through landmine-strewn jungle in the Siem Reap region where Angkor Wat, the largest Hindi temple complex in the world, is located. The expedition used an instrument called Lidar — light detection and ranging data — which was strapped to a helicopter that criss-crossed a mountain north of Angkor Wat for seven days. It effectively peeled away the jungle canopy using billions of laser pulses, allowing archaeologists to see structures that were in perfect squares, completing a map of the city which years of painstaking ground research had been unable to achieve.”
