The Great Dismal Swamp (the swamp) is a forested peatland in southeastern Virginia and northeastern North Carolina. Since early colonial times, timber harvesting and drainage through a network of ditches constructed to facilitate the harvesting have altered these ecosystems. The U.S. Fish and Wildlife Service has managed the swamp as the Great Dismal Swamp National Wildlife Refuge since 1974 to restore its forest communities to those present in early colonial times. Part of the approach to forest restoration has been to "restore the hydrology." The report by Speiran and Wurster (2020) describes the hydrology and water quality across the swamp. Part of the data used to describe the hydrology and water quality of...

Mapping of the current distributions of forest-cover types across the Great Dismal Swamp National Wildlife Refuge (the swamp) is critical to understanding the success of ongoing hydrologic and other management techniques used to restore the forest communities of the swamp to those present across the swamp in early colonial times. Aerial photographs, orthophotographs, and vector digital data were used to map forest-cover types of the swamp. The forest-cover types were interpreted and mapped using composition, height, and canopy-closure classes derived from this imagery and field verification. The imagery was obtained using a near-infrared sensor (NIR) carried in an airplane flown across the swamp during the mid-to-late...
