Habitat points collected in the field in addition to the planned habitat points placed across the Masonboro Island study site. Each point was examined using imagery from various sources, including Google Earth, Google Maps, North Carolina OneMap, and the National Agriculture Imagery Program (NAIP) to determine whether the point matched its previous NWI habitat type designation, and to update the point if it did not match its previously given habitat type. Confidence levels were then assigned to each point’s full NWI habitat code as well as to each point’s NWI habitat code shortened to contain the habitat’s main system, subsytem, and class levels.
