Savage Minds points us to the Nature.com article about an Italian programmer who, while scooting around his home town on Google Earth and Google Maps, stumbled upon the remains of an ancient villa.

Using satellite images from Google Maps and Google Earth, an Italian computer programmer has stumbled upon the remains of an ancient villa. Luca Mori was studying maps of the region around his town of Sorbolo, near Parma, when he noticed a prominent, oval, shaded form more than 500 metres long. It was the meander of an ancient river, visible because former watercourses absorb different amounts of moisture from the air than their surroundings do.

His eye was caught by unusual 'rectangular shadows' nearby. Curious, he analysed the image further, and concluded that the lines must represent a buried structure of human origin. Eventually, he traced out what looked like the inner courtyards of a villa.

Mori, who describes the finding on his blog, Quellí Della Bassa, contacted archaeologists, including experts at the National Archaeological Museum of Parma. They confirmed the find. At first it was thought to be a Bronze Age village, but an inspection of the site turned up ceramic pieces that indicated it was a Roman villa.

These tools are so powerful because they open up whole new lines of knowledge and inquiry to everyone who has access to the internet, most importantly to the locals who have both the interest and the indigenous knowledge to make discoveries that scientists at far away Universities never could.
