As a side project, the Bureau wanted to collect some sample data to try different approaches to ground classification, and decided to do so at the nearby Maya site of Copan in western Honduras. "However, the layout of the settlement itself tells us that planners and many active hands were at work here," says Heiko Prmers. Although LiDAR has been used for decades in geomorphology studies (primarily airborne and tripod systems), mobile LiDAR systems are only just beginning to be used. Here are just a few of the amazing discoveries that have been made with LIDAR technology. The newest generation of tripod and mobile LiDAR scanning systems offer the ability to measure surface topography in unprecedented detail. Laser technology known as LiDAR digitally removes the forest canopy to reveal ancient ruins below, showing that Maya cities such as Tikal were much larger than ground-based research had suggested. With a combination of excavation and LIDAR Technology, its possible that many more exciting discoveries await. Angkor Wat is the most famous structure in the complex, and is the largest religious structure in the world. These different angles improve the chances that part of a laser beam will slip through gaps in the foliage and reach the ground, resulting in fewer wasted canopy-only shots. These technologies made the survey in Honduras quite successful, covering 140 square kilometers in only eight flights and revealing several small settlements composed of structures and plazas scattered here and there. The team is excavating household clusters on the edge of Coba and Yaxuna along the Great White Road to find similarities in goods between the two sites.
