What would we learn and what could we save, if we had a 3D-scan of the entire earth?

LIDAR technology is an innovation in archeology and ecology that has uncovered lost civilizations. But archeologist Chris Fisher realized it could help track and study the effects of climate change.

Christopher T. Fisher is an archeologist, professor of anthropology at Colorado State University, and a National Geographic Explorer. He is also the founder and co-director of the Earth Archive, which is an initiative to scientifically document the entire surface of the Earth using 3D technologies before it changes forever. Since the early 1990s, his archeological research has centered on unraveling the complex set of social and environmental variables that resulted in the formation of the Late Postclassic (CE 1350-1520) Purépecha (Tarascan) Empire located in the Lake Pátzcuaro Basin, Michoacán, Mexico. During the course of this work in 2007, he and his team first documented an ancient city that they now call Angamuco.

Chris's work explores the connection between human societies and environments through a variety of archaeological and earth science methodologies including geoarchaeology, full coverage survey, excavation, and remote sensing. He earned his master's and doctorate in anthropology from the University of Wisconsin in Madison and his bachelor's in anthropology and archeology from Michigan State University.
