The Oconee Rivers Audubon Society will launch its 2013-14 season with a presentation on the use of remote-control airborne cameras – drones – to map critical habitats at 7 p.m. Thursday, September 4, at Sandy Creek Nature Center. Thomas R. Jordan, associate director of the University of Georgia’s Center for Geospatial Research, will provide a detailed description of aerial drones, how they work and how they can be used in mapping and in other geography applications. Jordan is a leader in UGA’s Center for Geospatial Research, which promotes the application of geospatial technology in interdisciplinary research, education and public service. The center, part of the Department of Geography in UGA’s Franklin College of Arts and Sciences, specializes in remote sensing, geographic information systems (GIS), and other technologies that can be used in ecology, forestry, geography, geology and hydrology. The center recently completed the most detailed orthophoto and LiDAR (laser) mapping ever conducted for Great Smoky Mountains National Park in North Carolina and Tennessee and is now mapping vegetation in eight additional National Parks in the Southeast.
