Lost cities on Earth.

As Archaeologists have discovered multiple world heritage sites, that were previously undocumented. These include the medieval cities not far from the ancient temples of Angkor Wat. In Cambodia it has been groundbreaking for historians as these new discoveries promise to upend key assumptions about south-east Asia’s history. As Dr Evans, whose published his findings, these will be published in the Journal of Archaeological Science 2016. As he announce that cutting-edge science will be used, this will bring airborne laser scanning techniques. He revealed multiple cities have been discovered between 900 and 1,400 years old, beneath the tropical forest floor, some of Cambodia’s capitals cities similar to Phnom Penh. Some experts believe that the analysed data – captured in 2015 is the most extensive undertaken ever done to date on this region. This is by an 734 sq covering shows that the colossal, densely populated cities would have constituted the largest empire on earth by populations in and around at the time, of its peak in the 12th century. 

Evans said: “We discovered beneath the forest, that no one knew they were there. included was the survey of the ancient temples of Angkor Wat, Kompong this uncovered only a part of Mahendraparvata on Phnom Kulen in the 2012 survey. As this time we got the whole deal and it’s was big, the size of Phnom Penh its really that big.” As Laser technology reveals lost city around Angkor Wat. A research fellow at Française d’Extrême-Orient (EFEO) and the architect of the Cambodian Archaeological Lidar Initiative (Cali), Evans will speak at the Royal Geographic Society in London about the findings on Monday 13-6-16. Evans obtained European Research Council (ERC) funding for the project. Its based on the success of his first lidar search (light detection and ranging) survey in Cambodia in 2012. That uncovered a complex map network. Its connecting medieval temple-cities, such as being Mealea and Koh Ker, to Angkor, and its confirmed what they suspected, that there was a city beneath 'Mount Kulen'. It was not until the results of the significantly larger 2015 survey were analysed that the apparent. Mountain city allocator has uncovered and this survey including discoveries of systems that were built hundreds of years ago.

As historians debate like never before over the had findings. The ancient temples of Angkor Wat, existed. These challenge the theories on how the Khmer empire had dominated and developed. It yet went into declined around the 15th century and there with its climate management in that process? Coverage of the capitals also provides some fascinating new insights on the ‘collapse’of Angkor,” Evans said. “There’s an idea that somehow that back then. The invasion happened and everyone fled down south – that didn’t happen, there are no cities down south as revealed by the aerial survey, that they ever fled to. It calls into question the whole notion of an Angkorian civilisation collapse which maybe linked to desease” These temples at Angkor are across the UNESCO-protected regions that has become an archaeological park, these are the country’s top tourist destinations. As with the main temple-Angkor Wat, Cambodian national ancient temples of Angkor Wat, is the most extensive urban find since industrial times, it has a sophisticated water supply system. Angkor’s supposed to have been occupied. Archaeology as archaeologists have discover in Petra monument that could be dated to 2,150 years old. The new cities were found by firing lasers to the ground from a helicopter to produce extremely detailed maps of its surface.

Evans said new scanners had also identified large numbers of mysterious geometric objects like earthen embankments, these may have been gardens. As Experts in the archaeological world agree these are the new archaeological discoveries of recent years. Michael Coe, of anthropology at Yale University said its one of world’s pre-eminent sites at Angkor in Cambodia it specialises on civilisation. “I think that these airborne laser discoveries may mark the greatest advances into the past 50 or 100 years in universal history. Angkorian civilisation,” he said from Long Island in the US.

“I saw Angkor for the first time in 1954. Then I wondered at the magnificent temples, but there was nothing to tell us who had lived in the city, where they had lived and how such an amazing culture was supported. To a visitor, Angkor was nothing but temples and rice paddies.” Provided by this architecture in a forest in Cambodia Charles Higham, research professor at the University of Otago Zealand and the leading archaeologist of mainland south-east Asia. He said it was the most exciting papers he could recall reading. “I have been to all the sites described and at a stroke, they spring into life and it is as if a bright light has shone for us.This images illuminate the previous work that had a dark veil that covered these great sites.” Higham said. “Personally, it is wonderful to be alive. Now as these new discoveries are being made. Emotionally, I am stunned. Intellectually, I am stimulated.”

David Chandler, Monash University in Melbourne, Australia, the foremost expert on Cambodian history and the author of several books and articles on the subject, said the work was thrilling and credited. Evans and his colleagues with “rewriting history”. Chandler said he believed it would open up a series of perspectives as people know civilisation, come and eventually collapse. Related this is Why the new fossils have shed light on evolution of Flores, as ‘hobbits’“It will take time for their game-changing findings to drift out as guides, and published histories,” Chandler said. “But their success at putting hundreds of ordinary, nameless, people back into Cambodia’s past is a giant step for anyone and one for Cambodian history.”David Kyle, an archaeologist and ecological anthropologist has conducted a study of Phnom Kulen, the location of the biggest findings, there past and Mahendraparvata, is the size of Phnom Penh, beneath the forest floor he said. This has evolutionised our approaches. It’s excited us. It facilitates a paradigm shift in our comprehension of the complexity, size and the questions we can address.”

While the 2012 survey identified a sprawling, highly urbanised growth Angkor, including rather “spectacularly” in the “downtown” area of the temple-city of Angkor Wat, the 2015 project has revealed a similar pattern of equally intense urbanised to the remote archaeological both in pre- and post-Angkorian sites. Graphic of lidar images as Dr Peter Sharrock, who is on the south-east Asian board at London University’s School of Oriental and African Studies and has a decades-long connection to Cambodia, said the findings showed “clear data for the first time of dense populations settled in and around all ancient Khmer temples”. “This urban and rural landscape, linked by road and canal networks, now seems to have constituted the largest empire on earth in the 12th century.” Sharrock said Evans, whose domain is an air-conditioned room full of computers shows archaeological centre in Siem was Reap, rather dirt trenches we are modest about his achievements and quick to credit his colleagues on the Cali project. Ancient temples of Angkor Wat,  he believed the discoveries would completely upend many assumptions about the Khmer empire. He also hoped it would bring the study of people back into the picture. Coe, who has been to many of the places covered by the survey and has seen the imagery, said that while the 2012 survey of Kulen and Phnom

Technology could do – “it as could look through the dense jungle covering these hills and reveal an unexpected city which predated Angkor itself” – the 2015 survey took this into new dimensions. This view had begun Hendrickson, the director of the industries of Angkor project and assistant professor in this department from University of Illinois. This survey has been “an incredible leap forward” in archaeologists’ ability to see everything for the first time and had been “a major game-changer” in understanding how the Angkorian Khmer people who built, modified and lived in their cities. But he was “stunned” by the second survey. “The results for Preah Khan of Kompong Survay are truly remarkable and are arguably the jewel in the crown of this mission. The lidar shows us that there was much, much more,” Hendrickson said, referencing a full-blown community layout that was previously unknown. “It’s both humbling and exciting. There are so are its discoveries.” “We knew that Preah Khan of Kompong Svay was significant before the lidar – it’s the largest complex.

Angkorian period has connected to Angkor directly by a major fitted site with substance it had played a role in facilitating the iron supply to the capital. École Reap’s Siem Orient look at a map of the site. “The new results suggest that it may have been more important than many temples built in Angkor and that it had a decent-sized population supporting it.” Dr Martin Polkinghorne, a research fellow in the department of archaeology at Adelaide’s Flinders University who is conducting a joint research project on Longvek and Oudong, the post-Angkorian capitals, said his team would use the new scheduled until these cities were built. “The decline of Angkor is among the most significant events in the history of south-east Asia, but we do not have a precise date for the event,” Polkinghorne said. “By using lidar to guide excavations on the capitals of Cambodia that followed we can determine when the kings of Angkor moved south and clarify the end of Angkor.

Also are related are the drowned worlds they have been posted these are Egypt's lost cities. “Cambodia happened after that its understood in terms of loss, retreat and absence; A dark era in Cambodian history was lost as in Angkor. As South-east Asia was the hub of international trade between east and west. Using the lidar at Longvek and Oudong in combination with conventional archaeology we will reveal the dark age as equally rich, complex and diverse.” What is a lidar survey? An airborne laser scanner (ALS) is mounted to a helicopter skid pad. Flying with pre-guidelines, Its determined flight path and airspeed, the ALS pulses the terrain with more than 16 laser beams per square metre during flights. The time the laser pulse takes to return to the sensor determines the elevation of each individual data point. This data is downloaded and calibrated and creates a 3D model of the information captured during the flights. In order to negate tree foliage and man made obstacles from the data, any sudden and radical changes mapped out, with models of the thresholds in processing these data points. Once completed, its handed over to analysis teem, which can take months to process into maps. As middle east cross roads to the ancient open their gates to lost civilisations.
