New Tech Sees Dead People

•The hyperspectral cameras detect slight changes in light coming from plants and bare soil.
•Researchers expect to discover mass graves and close missing persons cases using the tech.

The site of an animal cemetary in Quebec, Canada detected by hyperspectral imaging

A spooky-sounding technology is finding old, unmarked graves. Using hyperspectral imaging, scientists from McGill University have found unmarked animal graves with special cameras that measure changes in the light coming from soil and plants.

Hyperspectral imaging collects and processes light from across the electromagnetic spectrum, including visible light, as well as ultraviolet and infrared light. The research could help police solve missing persons cases or reveal new mass graves from hundreds, if not thousands, of years ago.

"As soon as there is some decay you can see a difference," said Andre Costopoulos, a professor at McGill University developing new techniques to find old graves.

"We suspect that some of these graves are over 40 years old, and are excited to try to find much older grave sites," some of which could be hundreds of years old, said Costopoulos.

The McGill project began in an unlikely place: an African animal safari park in Quebec called Parc Safari. Parc Safari officials wanted to exhume a buried elephant and reassemble the bones for an park exhibit. But the park official didn't know where the dead elephant was buried.

Costopoulos was enlisted to find the missing elephant. Over three seasons Costopoulos' team found seven animal graves at depths of two to three feet deep (including the elephant). They knew more animal graves existed at the site.

Sad that it is needed for some of these purposes.

1. so long as it's not Dead Men Walking.

I remember when the USSR collectively shit its pants after the USAF announced that it developed a new radar that found the old path of an ancient Suez canal, burried under 10 meters of sand. What the US really did was to warn the Soviets that their buried missile silos were visible.

It is no surprise that as we get more creative about how we look at things, the more we see.

I suspect Jimmy Hoffa will still remain unfound.
