Recent advances in remote sensing technology, such as airborne LiDAR scanning, have greatly facilitated the surveying and identification of archaeological sites. This technology has made it possible to detect traces of ancient societies in heavily forested areas that would have otherwise remained invisible to satellite imagery. LiDAR instruments mounted underneath an aerial platform emit approximately a million pulses per second, which can penetrate through the foliage and generate extensive 3D point clouds of the forest floor. These point clouds can be processed to remove the foliage cover and provide a precise and detailed map of the underlying terrain. Archaeologists can then use this information to analyze and categorize anthropogenic structures and plan potential explorations on site.
