Summary

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 spring of 2015. [...]

Purpose

Mapping forest-cover type is a fundamental approach for assessing the success of hydrologic and other management techniques used to restore forest-cover types across the Great Dismal Swamp National Wildlife Refuge (the swamp) to those present in early colonial times. The accompanying data were used to map forest-cover types across the swamp.
