High resolution images of coast available

The Coastal Resources Division(CRD) of the Georgia  Department Natural Resources (DNR) in partnership with coastal counties and federal, state and local resource agencies recently acquired high resolution aerial images of coastal Georgia.  These images, commonly referred to as orthoimagery data, are highly accurate and are used in geographic information systems (GIS) by local, state, and federal governments, natural resource managers, land use planners, foresters, and researchers.

State resource agencies such as DNR use this imagery for a variety of purposes including habitat mapping, land use analysis and permitting.  When up- to-date images are needed the Department will utilize photography taken from helicopters which provides an instantaneous image of a small scale area.  However, this is not practical for large areas nor is it spatially accurate for use in GIS.

“The new orthoimagery dataset provides an accurate, high resolution, regional picture of coastal Georgia,” says Sonny Emmert, CRD coastal resources specialist.  Besides being of great value to DNR, local governments and other state and federal agencies will benefit greatly from this dataset.”

The imagery project began in late 2011 when Savannah Area GIS brought the partners together.  The aerial orthoimagery was acquired during January 2013 at low tide by PhotoScience and delivered to DNR and the multiple partners: county governments of Chatham, Bryan, Effingham, Liberty, Bryan, McIntosh, Glynn, University of Georgia, Coastal Regional Commission, U.S. Fish and Wildlife Service, NOAA, and the U.S. Geological Survey.  Participation by such numerous partners lowered the individual cost contributions, assisted in gaining project support, and ensured thorough regional coverage.

The imagery is now available for download through the NOAA Coastal Services Center Digital Coast website at https://www.csc.noaa.gov/digitalcoast
