LIDAR Mapping Reveals a Far Greater Mayan Civilization

A 2016 aerial survey of ten sites in Guatemala’s Maya Biosphere Reserve used LIDAR to digitally remove the tree canopy from the landscape, revealing, National Geographic reports, “the ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed”—and one that likely supported a much higher population than previously thought. The survey and its findings are the subject of a documentary special premiering tomorrow on the National Geographic channel. More coverage: CBC NewsThe New York Times, The VergeThe Washington Post.

Guatemala’s Giant Relief Map

Atlas Obscura has the story of Guatemala’s Mapa en Relieve, an exaggerated-relief 3D relief model of the country. The 1:10,000-scale horizontal, 1:2,000-scale vertical map is approximately 1,800 square metres in area and made of concrete. Built by Francisco Vela and put on display in 1905, the map includes present-day Belize as part of Guatemala, which claimed the British Honduras at that time. It kind of reminds me of British Columbia’s Challenger Map, only a half-century older and made of concrete rather than wood. [WMS]
