Pyramid structure discovered near Caral Peru

There is so much to discover in that region. On a geology class field trip, a few hours south of Lima, our instructor stopped and pointed out a mound that would not have caught my eye at all. Then he explained how it makes no sense for a geological feature like that to be there.<p>It was a covered structure. A Huaca. Lima has quite a few in the middle of the city. A stark reminder that we’ve been there ,intermittently, for millennia.

Have there been any recent books that try to reconstruct what pre-Columbian South America was like?<p>I know that 1491 was a pretty good book about this. But it&#x27;s like 20 years old now. And Lidar seems to have really opened up new insights in the past decade or so.

&gt; Chupacigarro<p>I love it when a plan comes together.

Has anyone worked on AI&#x2F;ML approaches for detecting ancient structures in LiDAR data? Given that training data for identifying remnants of man-made structures (e.g., Roman or medieval ruins) is quite sparse, how would you approach this problem?<p>Some initial thoughts:<p>- Data Augmentation: Using synthetic or simulated LiDAR data from known structures to improve training. - Few-Shot Learning &#x2F; Transfer Learning: Training models on better-documented archaeological sites and applying them to new areas.<p>Would love to hear thoughts from people with experience in remote sensing, computer vision, or archaeology!

Huh, I had not heard of Caral. This culture is apparently much older than the Incas. Like, 2000 BC rather than 1500 AD.

The fact that a pyramid was hidden for so long, just a kilometer from Caral, makes you wonder what else might still be buried in the region
