HATTERAS_SHORELINES_1978_2002: Hatteras Island shorelines from 1978 to 2002: fourteen high water shorelines from Oregon Inlet to Cape Hatteras Point, North Carolina (geographic, WGS84).

The shoreline of Cape Hatteras, North Carolina, is experiencing long-term coastal erosion. In order to better understand and monitor the changing coastline, historical aerial imagery is used to map shoreline change. For the area of Hatteras Island from Cape Point to Oregon Inlet, fourteen aerial datasets from 1978-2002 were scanned and georeferenced for use in a Geographic Information System (GIS). Shoreline positions (high water line) were digitized from georeferenced imagery. The shoreline vectors were then compiled for use in the Digital Shoreline Analysis System (DSAS) ArcGIS extension in order to generate rates of shoreline change.

北卡罗来纳州哈特拉斯角（Cape Hatteras）的岸线正遭受长期海岸侵蚀。为更好地理解并监测岸线动态变化，研究团队采用历史航空影像开展岸线变化制图工作。针对哈特拉斯岛从霍特角（Cape Point）至俄勒冈湾口（Oregon Inlet）的区域，研究人员对1978年至2002年间的14份航空数据集进行扫描与地理配准，以应用于地理信息系统（Geographic Information System, GIS）。从经地理配准的影像中数字化提取岸线位置（即高水位线），随后将岸线矢量数据整合，用于数字岸线分析系统（Digital Shoreline Analysis System, DSAS）的ArcGIS扩展工具，进而生成岸线变化速率。
