A research group led by Professor Masato Sakai of Yamagata University discovered 143 new geoglyphs in and around the Nazca Plateau in Peru, South America.One of these points has been confirmed in a demonstration experiment that processes aerial photographs using AI (artificial intelligence) conducted jointly with IBM Japan.In the future, we will create a distribution map of geoglyphs based on field surveys, grasp the whole picture, and accelerate conservation activities.
According to Yamagata University, this discovery was found in high-resolution 2016D image analysis and field surveys using drones from 2018 to 3.There are two-headed snakes with a total length of about 20 meters that try to swallow people, and those depicting orca and birds with a total length of over 100 meters, and it is estimated that they were drawn between 100 BC and 300 BC. ..
In a joint experiment with IBM Japan, when AI was made to learn geoglyphs and searched for geoglyphs from aerial photographs of Nasca, more than 500 candidates were raised.As a result of a field survey at Yamagata University, it was confirmed that the design of a person with a cane with a total length of 5 meters was a geoglyph.
Nazca's ground paintings are geometric figures and animal paintings drawn on the plateau of the basin surrounded by the Nazca and Ingenio rivers in Peru, and were registered as a UNESCO World Heritage Site in 1994.So far, 70 to 80 geoglyphs have been found.
Yamagata University has signed an academic agreement with IBM Watson Institute in the United States to carry out joint research.In the future, we will try to grasp the distribution of geoglyphs using IBM's AI platform.
