Dr. Juan Carlos Fernandez-Diaz has been with The National Center for Airborne Laser Mapping (NCALM) since 2005 and has coordinated 18 archaeological lidar surveys totaling over 5600 km. Unlike the survey of Copan, this one was intended to be an archaeological survey from the start. Even though the savannah plain, which flooded several months a year during rainy season, does not encourage permanent settlement, there are still many visible traces of the time before Spanish colonization at the beginning of the 16th century. It implies a low degree of sociopolitical complexity and integration, Canuto said. 3+ PHD (some are still teaching at universities) on board. Archaeologists at Miami University and the Yucatan have carried out the first lidar study of the 80 mile stone highway (sacbe) that connected the Maya sites of Coba and Yaxuna in the Yucatan. Mexico is even more fascinating because archaeologists found 478 new Mesoamerican sites dating between 1400 B.C. As in so many domains, tech is an enabler (Prmers estimated it might have taken 400 years of digs to unearth all the things they found using lidar) but can never replace the hard work and expertise that humans bring to the equation. Credit: Heiko Prmers / DAI. Lidar had been used by archeologists since the 1970s to map European castles and structures, but always in open areas and fields. . Aerial sensors such as LIDAR are particularly effective at showing the characteristic rises in topography that mark the presence of mounds. Takeshi Inomata, from the School of Anthropology at the University of Arizona said . While NCALMs current schedule includes more surveys in Mexico, Guatemala, and Central America, the next big frontier is expected to be the Amazon.
