A research team from Yamagata University, in collaboration with IBM, has made a groundbreaking discovery by utilizing AI to survey the Nazca Lines. Over a six-month period, they identified 303 new geoglyphs, nearly doubling the number of known figures on the Nazca Plateau. The team employed cutting-edge technology to analyze a vast array of aerial photographs, significantly increasing the probability of discovery by 16 times. The newly discovered geoglyphs, which are estimated to date from 100 BCE to 50 CE, predominantly depict humans and camelid animals like llamas, with an average length of about 9 meters. The research revealed two main types of geoglyphs: "surface type," which were likely used as markers and can be observed from small paths, and "line type," which are larger and believed to have been created for communal ritual activities. The study's findings, which shed light on the cultural aspects of the Nazca society, are set to be published in the Proceedings of the National Academy of Sciences (PNAS). Professor Masato Sakai noted that the use of AI has accelerated the research pace, paving the way for the discovery of even more geoglyphs and a deeper understanding of their purposes.
