Lidar Finds Overgrown Maya Pyramids

AlejoHausner writes "A team of archaeologists scanned the jungle of Belize with lidar. Although most of the reflections came from the jungle canopy, some light reflected off the ground surface. Using this, suddenly hidden pyramids, agricultural terraces, and ancient roads are revealed, at 6-inch resolution. The data allowed the archaeologists to bolster their theory that the ancient city of Caracol covered more than 70 square miles of urban sprawl and supported a population of over 115,000."

Other uses for this technology

[adeft]

Seems like it might be useful for finding downed aircrafts and other missing objects....maybe even people?

Great thought, but the time to process lidar data takes a while. So planes and objects sure, but even the logistics to get this done takes time. Not sure about people, due to resolution over a vast area and again logistics. The bare-earth relief (which strips away a degree of vegetation) lidar offers is incredible. Cartographers and geologist have only recently really taken advantage of the technology. But in time and $, these other uses could definitely be considered, especially when resolution and processing is more developed.

The summary alluded to this but mostly what you get is reflection off the canopy... when you start talking dense jungle.. triple canopy type areas then this is not going to be effective...

I built an irony detector, but it only detects 'everything but irony'.

Now find Atlantis.

You mock, but the discoveries of megalithic structures over the past twenty years have called into question a lot of our assumptions about the earliest civilizations with technology. There are rock carvings being discovered in the Southern part of Africa that show very advanced understanding of astronomy, geography and time measurement that appear to be over twenty thousand years old which is much, much earlier than previously thought.

If we can ever get scientists to be able to really research the pyramids and nearby structures without the dictatorial control of the Egyptian government, there is reason to believe that there are references to sophisticated understanding of astronomy going back over fifty thousand years.

When I worked at the University of Chicago, I used to hang with people from the Oriental Institute. From them, I learned just how shaky a lot of the theories regarding Early Egyptian culture really are, including but not limited to how in the hell the pyramids were built. One of the foremost Egyptologists in the world once confirmed to me that the accepted theories are clearly ridiculous, that the notion that you can drag, or roll on logs, granite blocks weighing up to 100 tons for several miles, and then erasing every sign of the way in which they were moved, is just nonsense. Further, he'd like to know, how in the hell were they able to move those stones over 100 feet in the air to place them at the top of the pile?

This gentleman, now dead, explained that Egyptology specifically, and archeology generally, are so political that any theory or work done outside the mainstream is killed before it can even be peer-reviewed. This guy, a professor emeritus at the time, told me he'd had a 20 year correspondence with crypto-archeologist Graham Hancock and he was careful to tell me that though he disagreed with most of Hancock's assertions, that some of them deserved much closer consideration. And it's not only academic politics that have shaped our "consensus" regarding those civilizations. Religious and political forces have played an even greater role in making sure that the accepted history supports certain orthodoxies.

Atlantis? Well, probably not, but once you get past 50,000 years it's not at all impossible that there was a relatively advanced civilization on this planet that subsequently disappeared. Almost every native culture on Earth has legends about a "golden age" when a more advanced civilization existed, which then disappeared during a subsequent "dark age".

You don't even have to go back that far. The Minoan people of ancient Crete were well on the way to an industrial revolution of of their own that predated that of England by a couple of thousand years. If it wasn't for an inopportune volcanic eruption which completely wiped the Minoans out back around 1400 BCE, we might have had electronic computers by Roman times and those flying cars and jet packs we all wish for by now.

The Egyptians were experts in using water. Easy to level the base of the pyramids, just flood the whole area on a calm day, and mark the water level. Likewise, why drag/roll stones for miles when you can just build a canal and float them to the work site? With use temporary dykes and thousands of people to pump water up hill, you could practically float them into place and drop them. Of course, there would be no trace left of temporary systems put in place to move stones, be they canals or ramps, any more than there are traces of scaffolding around the great cathedrals.

I also find silly our clinging to the belief that there was absolutely no interaction between Egyptian and South American civilizations, despite growing evidence of "native" South American plants showing up in ancient Egypt. It seems like blatant Euro-centricism to assume that Europeans were the only ones capable of "discovering" new continents, especially since these continents were already inhabited by other peoples!

A volcano... or the horrific results of their experimentation with bio-engineering and the creation of a man-bull hybrid?!

Food for thought.

[Sleepy]

It would be more accurate to say your history books are full of mistruths, but if you want examples, just pick nearly any thing from a high school history book... and then REALLY research it.

1) We're all told that Benedict Arnold was simply a traitor to the American Revolution... but not that he was mistreated prior to that. (note: I'm not drawing judgment, these are simply facts).
2) We're all told that the "Americas" were sparsely populated by a few tens of thousands - not millions - of "natives". The "Trail of Tears" gets about 1/2 page coverage - scant compared to other 19th and 10th century genocides..
3) General Custer died a hero, and was NOT a coward who engaged in genocidal killings of women and infants.
4) Jesus was blonde, blue-eyed, and never took a wife

I'm just rattling off 4 I could think of inside of a few seconds.

(And to any perceived anti-US bias comments, it's untrue to suggest that. I happen to be most familiar with my own culture and therefore capable of poking holes in the lies it teaches. Every culture is guilty of this, but I can't be expected to have the same level of familiarity with those other cultures. Whatever, most people get it right?)

Ah, so THEY are the originators of ManBearPig!

I have problem with people making statements about how the pyramids could not be built with the technology available. So called crop circle experts said there was no way humans could be behind crop circles, until they were shown video of two retired guys and a wood plank in fact doing it. People used to talk about how it was scientifically impossible for a bumble bee to fly, but yet it does.

I think some people think too highly of their ability to figure things out, and they don't give other people enough credit for their ingenuity.

Fast turnaround

[JustNilt]

What's most impressive to me is how quickly they got the results. It only took a couple days of actual data gathering then a few weeks of lab processing. Last I heard about anything similar (using satellite images, IIRC) it took months to get results.

Very cool stuff.

The NYT article was actually pretty good, but for those who want a bit more 'meat on the bone', here's the 2009 research project report:

There are some nice examples of the LIDAR images at the end of the page in the Figures section.

[city]

I was there in November and they have done a really good job there leaving some of the city as it exists today overtaken by the jungle and some restored to show how the Maya lived in the cities. You would have no idea the mounds and hills of the jungle are pyramids and structures. The people there say you can't buy land without diggin up a Maya house in your backyard. Today in Belize there are around 300,000 people in the whole country, versus estimations before the Maya collapse of a couple million. For perspective the largest city there today only has 70,000 people.
