Airborne laser technology have busted a network, roads and canals, connect Cambodia, the famous Angkor Wat temples out of the bustling city.
The discovery was announced on Monday night in the early release of the national academy of sciences journal articles peer review sheets of paper. Laser scan revealed no record before formal planning of urban landscape with 1200 years of ancient temples.
Cambodia, angkor temples, the most popular tourist destinations and one of Asia's most famous landmarks, was built in the 12th century, the powerful Khmer empire. Angkor Wat is the pride of Cambodia deep point, appear on the flag, named as a UNESCO world heritage site.
Archaeologists have long suspected the phnom penh, siem reap Kulen mountain vegetation under the dense canopy hidden city Mahendraparvata layoffs. But first airborne laser produced a huge detailed maps of urban landscape, including roads and previously undiscovered temple.
"No one has ever before mapping the details of the city, any kind, so it is a real inspiration to see so clearly reveal the city," archaeologist damien Evans in Sydney, the study's lead author, university, said by telephone from Cambodia. "It's fantastic, see the traces of human activity is still engraved on the ground of the forest are many, many centuries, after the city, stop working, and growing."
, called laser radar, laser technology, the working principle from the plane to ground laser pulse and measure the distance, in order to create a detailed, three-dimensional region of the map. This is a useful tool, archaeologists, because the laser can penetrate the thick vegetation, far faster than they can walk on and cover large tracts of the ground for analysis. Laser radar has been used to explore other archaeological sites, such as the huge rock.
In April 2012, the researchers on the helicopter loaded equipment, spent days crisscrossed the dense forests, 800 meters (2600 feet) above the ground. Australian and French archaeologist and a team of the results of a survey has confirmed that on foot through the jungle in search of adventure.
Archaeologists have spent years doing field research, mapping a 9 square kilometers (3.5 square miles) of prosperous area of the city. But the centre of laser radar for the much larger - at least 35 square (14 square miles) in male - populous more than once thought.
, "Evans said:" is to find the real revelation, densely populated downtown, formal planning is greater than previously believed. "To see things, we missed before has completely changed our understanding of how these structures of the city."
Researchers don't yet know why Mahendraparvata civilization collapsed. But Evans said, the current theory is that the city's water management system may have driven the potential problems.
