With the use of Lazers (LiDAR) a new really big Mayan Megacity complex has been revealed in Guatemala. That itself is impressive but happens from time to time. What´s out of the ordinary here is that the Mainstream Science outlets are saying that this complex was able to inhabit and sustain 10 to 15 million People. Thats millions !!!
Remember that Rom at it´s hight in the roman empire had 1 million inhabitants. That mayan Area had about 10 million if not 15 million inhabitants. Amazing that mainstrean Science has no problem with that. Just think of the logistics, water and food supply etc.....

Exclusive: Laser Scans Reveal Maya "Megalopolis" Below Guatemalan Jungle

In what’s being hailed as a “major breakthrough” in Maya archaeology, researchers have identified the ruins of more than 60,000 houses, palaces, elevated highways, and other human-made features that have been hidden for centuries under the jungles of northern Guatemala.
Using a revolutionary technology known as LiDAR (short for “Light Detection And Ranging”), scholars digitally removed the tree canopy from aerial images of the now-unpopulated landscape, revealing the ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.
“The LiDAR images make it clear that this entire region was a settlement system whose scale and population density had been grossly underestimated,” said Thomas Garrison, an Ithaca College archaeologist and National Geographic Explorer who specializes in using digital technology for archaeological research.
Garrison is part of a consortium of researchers who are participating in the project, which was spearheaded by the PACUNAM Foundation, a Guatemalan nonprofit that fosters scientific research, sustainable development, and cultural heritage preservation.
The project mapped more than 800 square miles (2,100 square kilometers) of the Maya Biosphere Reserve in the Petén region of Guatemala, producing the largest LiDAR data set ever obtained for archaeological research.
The results suggest that Central America supported an advanced civilization that was, at its peak some 1,200 years ago, more comparable to sophisticated cultures such as ancient Greece or China than to the scattered and sparsely populated city states that ground-based research had long suggested.
In addition to hundreds of previously unknown structures, the LiDAR images show raised highways connecting urban centers and quarries. Complex irrigation and terracing systems supported intensive agriculture capable of feeding masses of workers who dramatically reshaped the landscape.
The ancient Maya never used the wheel or beasts of burden, yet “this was a civilization that was literally moving mountains,” said Marcello Canuto, a Tulane University archaeologist and National Geographic Explorer who participated in the project.
“We’ve had this western conceit that complex civilizations can’t flourish in the tropics, that the tropics are where civilizations go to die,” said Canuto, who conducts archaeological research at a Guatemalan site known as La Corona. “But with the new LiDAR-based evidence from Central America and [Cambodia’s] Angkor Wat, we now have to consider that complex societies may have formed in the tropics and made their way outward from there.”
Laser technology known as LiDAR digitally removes the forest canopy to reveal ancient ruins below, showing that Maya cities such as Tikal were much larger than ground-based research had suggested.

Surprising Insights
“LiDAR is revolutionizing archaeology the way the Hubble Space Telescope revolutionized astronomy,” said Francisco Estrada-Belli, a Tulane University archaeologist and National Geographic Explorer. “We’ll need 100 years to go through all [the data] and really understand what we’re seeing.”
Already, though, the survey has yielded surprising insights into settlement patterns, inter-urban connectivity, and militarization in the Maya Lowlands. At its peak in the Maya classic period (approximately A.D. 250–900), the civilization covered an area about twice the size of medieval England, but it was far more densely populated.
“Most people had been comfortable with population estimates of around 5 million,” said Estrada-Belli, who directs a multi-disciplinary archaeological project at Holmul, Guatemala. “With this new data it’s no longer unreasonable to think that there were 10 to 15 million people there—including many living in low-lying, swampy areas that many of us had thought uninhabitable.”

I was reading an article on this yesterday -- thanks for the images! I hadn't seen those yet. Very awesome find. I do recall a year or so ago tat this project was about to get underway, so awesome to finally have proof of the vastness of advanced ancient American civilizations, that most of us already highly new to be true ...

I saw this on the BBC web page yesterday looks interesting...

Lidar has revolutionised archaeology and it has come along way since Time Team.
Though it does beg the question what intel has been able to see for decades...
The oil and mineral industries have been using something similar for a long time
using frequencies if I remember right from a old HAARP vid ?

I have watched virtually every episode from the 1990's to when it ended a few
years ago...Originally they pushed it up and down the field like a push lawn mower
and probably still do.Time Team Digital S20 DIG2 DAY1- Emma explains the LIDAR

Sprawling Maya network discovered under Guatemala jungle

The Maya city of Tikal was found to be just a fraction of an immense hidden metropolis

Researchers have found more than 60,000 hidden Maya ruins in Guatemala in a
major archaeological breakthrough.Laser technology was used to survey digitally
beneath the forest canopy, revealing houses, palaces, elevated highways, and
defensive fortifications.The landscape, near already-known Maya cities, is thought
to have been home to millions more people than other research had previously
suggested.The researchers mapped over 810 square miles (2,100 sq km) in
northern Peten.Archaeologists believe the cutting-edge technology will change the
way the world will see the Maya civilisation.


https://ichef.bbci.co.uk/news/624/cpsprodpb/FC5E/production/_99860646_6_whiteboxes1_vlcsnap-error508.png
"I think this is one of the greatest advances in over 150 years of Maya
archaeology," said Stephen Houston, Professor of Archaeology and Anthropology at
Brown University.

Mr Houston told the BBC that after decades of work in the archaeological field, he
found the magnitude of the recent survey "breathtaking". He added, "I know it
sounds hyperbolic but when I saw the [Lidar] imagery, it did bring tears to my
eyes."

Great, yes. But, just to save me searching! Is there a specific LiDAR analysis of Tikal?

I'd love to see the comparison between the forest there (which is still thick and very extensive, despite all the excavation done) and what LiDAR shows is really there underneath it all.

Here is something mentioned about Tikal:
(translated from german)
Hope for many more discoveries
The Lidar study has also provided new insights to the well-known Mayan city of Tikal, which is a popular tourist destination in the jungle of Guatemala. A previously considered natural survey in the city center was therefore recognized as another pyramid. In addition, the city was in its heyday four to five times as large as previously thought. The researchers also hope that the planned continuation of lidar surveying will lead to many more discoveries. The archaeologist Francisco Estrada-Belli, for example, still expects hundreds of cities that are hitherto completely unknown. "The Lidar data rewrite the history of the Maya," says Albert Lin of National Geographic.


From the Ithaca College:
The survey of 2,100-square kilometers encompassed several major Maya sites, including the largest at Tikal, and El Zotz, where Garrison focuses his research. The LiDAR mapping revealed over 60,000 previously unknown structures in total, from unknown pyramids, palace structures, terraced fields, roadways, defensive walls and towers, and houses. Archaeologists are realizing that the ancient population centers they’ve spent decades studying are much bigger than they speculated.
“Everyone is seeing larger, denser sites. Everyone,” Garrison said. “There's a spectrum to it, for sure, but that's a universal: everyone has missed settlement in their [previous] mapping.”
Especially telling to Garrison are newly revealed agricultural features that would be necessary to support the lowland Maya population during their centuries of civilization — population estimates have now expanded from a few million to 10-20 million — and defensive structures that suggest warfare was far more prevalent than previously known.
