Innovative Technologies Used to Investigate Segments of the Inca Road

A groundbreaking study of the Qhapaq Ñan, the Andean Road System, reveals sustainable engineering practices employed by the Inca civilization. The research, supported by the National Science Foundation and Smithsonian Institute, utilized advanced technologies such as satellite communication systems, GIS/GPS mapping, photogrammetry, laser range finding, and ground-penetrating radar (GPR) to analyze the road's design and construction methods in extreme conditions. These findings highlight innovative techniques that could inform modern engineering practices. The study also showcased its discoveries globally through live interactive satellite broadcasts, providing a unique educational experience for visitors at the National Museum of the American Indian.
