Classification of geoglyphs and walking routes found on the Nazca Pampa. Walking routes are divided into winding trails and formal roads, while geoglyphs are divided into geometric and figurative. The geometric geoglyphs can further be divided into linear and areal, whereas the figurative geoglyphs can be divided into those produced in the line-type style and those in the relief-type style. This classification follows the one proposed by Lambers (3). With the help of AI, we were able to detect many new relief-type figurative geoglyphs. The improved inventory clarifies that line-type figurative geoglyphs are associated with the network of geometric geoglyphs and major roads (blue), whereas the relief-type figurative geoglyphs are associated with informal walking trails (green).
