Georeferenced Aerial Imagery of Hatteras Island from Oregon Inlet to Cape Hatteras, North Carolina 1978 - 2002 (North Carolina State Plane, NAD83, Feet)
This data series will be published by the USGS at a later date.
Fourteen sets of hard copy historical aerial images were acquired from the US Army Corp of Engineers, Field Research Facility, Duck, NC. These were digitally scanned and georeferenced to 2007 NC state orthophotography, (1:4,800, 1ft pixel, color, NAD83, North Carolina (ftUS)) using ERDAS Imagine (v9.3). Eight to ten control points were established for each image by visually identifying coincident points between the historical imagery and the orthophotography. Additional points were added as necessary to achieve acceptable root mean square (RMS) error (< 1 m). The images were georectified using a second order polynomial transformation with a nearest neighbor resample method and quality assessments were conducted. The average RMS value for each year is reported as the georeferencing RMS for that dataset which can be found in Table 1 of the corresponding Open File Report:
