Artificial Intelligence & Drones Uncover 303 New Nazca Lines in Peru

If you vis­it one tourist site in Peru, it will almost cer­tain­ly be the ruined Incan city of Machu Pic­chu. If you vis­it anoth­er, it’ll prob­a­bly be the Naz­ca Desert, home to many large-scale geo­glyphs made by pre-Inca peo­ples between 500 BC and 500 AD. Many of these “Naz­ca lines” are lit­er­al­ly that, run­ning across the desert floor in an abstract fash­ion, but oth­ers are fig­u­ra­tive, depict­ing human beings, flo­ra, fau­na, and var­i­ous less eas­i­ly cat­e­go­riz­able chimeras. The preser­v­a­tive effects of the cli­mate kept many of these designs iden­ti­fi­able by the time mod­erns dis­cov­ered them in 1927, and thanks to arti­fi­cial-intel­li­gence tech­nol­o­gy, researchers are find­ing new ones still today.

“A team from the Japan­ese Uni­ver­si­ty of Yamagata’s Naz­ca Insti­tute, in col­lab­o­ra­tion with IBM Research, dis­cov­ered 303 pre­vi­ous­ly unknown geo­glyphs of humans and ani­mals, all small­er in size than the vast geo­met­ric pat­terns that date from AD 200–700 and stretch across more than 400 sq km of the Naz­ca plateau,” writes the Guardian’s Dan Col­lyns.

“The use of AI com­bined with low-fly­ing drones rev­o­lu­tion­ized the speed and rate at which the geo­glyphs were dis­cov­ered, accord­ing to a research paper pub­lished this week in the Pro­ceed­ings of the Nation­al Acad­e­my of Sci­ences,” and many more Naz­ca lines could remain to be iden­ti­fied with these meth­ods.

The new­ly iden­ti­fied geo­glyphs “include birds, plants, spi­ders, human­like fig­ures with head­dress­es, decap­i­tat­ed heads and an orca wield­ing a knife,” writes CNN’s Katie Hunt. She also cites hypothe­ses about why the orig­i­nal cre­ators of these fig­ures did the painstak­ing work of dis­plac­ing stone after stone to cre­ate images most­ly invis­i­ble to the human eye: it’s pos­si­ble that “they formed a sacred space that was per­haps a place of pil­grim­age. Oth­er the­o­ries pro­pose they played a part in cal­en­dars, astron­o­my, irri­ga­tion or for move­ment, such as run­ning or danc­ing, or com­mu­ni­ca­tion.” Some of them, sure­ly, were meant only for the eyes of the gods, and so it may stand to rea­son that only our mod­ern gods of arti­fi­cial intel­li­gence have been able to reveal them.
