Ecuador has found a massive city concealed by the lush vegetation of the Amazon rainforest. A system of roadways and canals connected the homes and plazas in the ancient city located in the Upano valley, as reported by the BBC. The outlet went on to say that the region is shaded by a volcano, which has produced fertile local soils. LiDAR, commonly referred to as laser scanning or 3D scanning, is a widely used remote sensing technique that measures distances using light.
