The collection of about 300 giant geoglyphs known as Nasca Lines were etched into the ground in the Peruvian coastal plain 2,000-years ago by the Nasca culture in South America. They depict various plants, animals, and shapes and are so large that they can only be fully appreciated when viewed from the air. Unlike the NascaLines, most archaeological sites are hard to see from the air, especially those deep under thick jungle vegetation, as in the lowlands of northern Guatemala. Here, lidar’s ability to penetrate foliage makes it the ideal tool for archeological exploration. At the same time, the lack of infrastructure, including airports, makes UAVs the platform of choice for many such projects
