A new remote sensing technology has peeled away layers of mud and rock near Peru's Cahuachi desert to reveal an ancient adobe pyramid, Italian researchers announced on Friday at a satellite imagery conference in Rome.

Via Quickbird, Masini and colleagues collected high-resolution infrared and multispectral images. After the researchers optimized the data with special algorithms, the result was a detailed visualization of a pyramid extending over a 97,000-square-foot (9,000-square-meter) area.

Airborne gravity gradient survey techniques were used decades ago to find or deposits especially uranium. Also simple 3D optical photography can pick up anomalies under the overburden.

Why did they build the Pyramids TITQ.
