A New Kind of Archaeological Remote Sensing

Actually, a very old kind:

The government is digging for treasure after a civic-minded Hindu village sage dreamt that 1,000 tonnes of gold was buried under a ruined palace, and wrote to tell the central bank about it. The state Archaeological Survey of India has sent a team of archaeologists to the village of Daundia Khera in Uttar Pradesh. They are due to start digging on Friday, Praveen Kumar Mishra, the head archaeologist in the state, told Reuters. Yogi Swami Shobhan Sarkar says the gold he dreamt of belonged to a nineteenth-century ruler, Rao Ram Bux Singh. He says he wants it in government hands to help India recover from an economic crisis. "I cried the day I realised that India is going to collapse economically," the seer told the Mail Today newspaper. The dead ruler's spirit has been roaming the palace and asking for the gold to be dug up, he added. "It is a hidden treasure for the country."
