Scientists have used helicopters equipped with laser radars. Scan air has helped discover an ancient city and make it a detailed map, including the streets, canals and temples. The technology allows you to get an accurate model of the ground surface, hidden from the eyes of almost impenetrable rain forest.
The technology is in the area irradiated with laser beam pulses which are followed continuously at high speed. Most of the light reflects and absorbs the foliage, but part of it still reaches the ground is reflected from it, and is captured on-board receiver.
Scientists have suggested why the city was abandoned. According to them, the reason probably lies in the peculiarities of terrain. “We assume that people were forced to leave the city because of severe environmental conditions: dry forest, the water was gone,” – noted the researchers.
