Hidden treasures

Animation showing three images over the eastern outskirts of Rome: archaeological chart showing the former sites of aqueducts, buildings and roads; Kompsat-2 panchromatic image acquired on 12 May 2009; and a Kompsat-2 multispectral (infrared, red and green) image from the same date.
The sites of two historical roads are visible in the images from 2009. The results were found by Chris Stewart of Rome’s Tor Vergata University.
