AI and Drones Uncover Hundreds of New Nazca Lines in Peru

AI and Drones Revolutionize Nazca Lines Research

In a groundbreaking study published in the Proceedings of the National Academy of Sciences, researchers have uncovered 303 previously unknown geoglyphs in Peru's Nazca Desert, nearly doubling the number of known figures. This remarkable discovery was made possible through the innovative use of artificial intelligence (AI) and drone technology, marking a significant advancement in archaeological research methods 1

Cutting-Edge Technology Meets Ancient Mystery

The research team, led by Masato Sakai from Yamagata University in Japan, employed a sophisticated AI system called ResNet50 to analyze high-resolution aerial images captured by low-flying drones. This AI-driven approach allowed researchers to scan an area of approximately 243 square miles, efficiently identifying potential geoglyph sites 2

Marcus Freitag, an IBM physicist collaborating on the project, highlighted the crucial role of AI in the discovery process: "Artificial intelligence was able to eliminate 98 percent of the images. Human experts now only need to confirm or reject plausible candidates" 1

New Insights into Nazca Culture

The newly discovered geoglyphs, averaging 30 feet across, offer fresh insights into the enigmatic Nazca civilization that flourished between 200 B.C. and 700 A.D. Among the intriguing finds are depictions of plants, people, animals, and even a striking 72-foot-long orca wielding a knife and severing a human head 1
