LiDAR technology helped researchers to uncover evidence of architectural structures hidden under vegetation in the vicinity of Machu Picchu in Peru. Among the newly discovered structures are terraces and platforms and pathways of the Inca Trail stretch. The discovery was made by a team led by Roland Fletcher of the University of Sydney.

Applied technology helped to reveal Incan buildings on the hillside of the citadel through aerial and three-dimensional images. They portray not only buildings, features of the landscape, including previous slides and erosions.

The images depict additional trails and provide evidence of terraces and forms that are likely to be constructions or stairways. This new date will be very helpful to point out places where to carry on future research.
