WMPO County Boundaries

The North Carolina Geodetic Survey developed the GIS data set, County Boundaries, surveyed to facilitate planning, siting and impact analysis in the 100 individual counties of North Carolina. This file shows some of the boundaries of counties which have a completed boundary survey but the majority of lines have not been surveyed. Also some boundaries cannot be surveyed in cases where boundaries are coincident with river centers. Refer to the 'County Boundary as Lines' to find out the source of the lines using the field attribute for 'DESC'. Most of the lines currently are from the DOT county maps which originally come from USGS but might have been updated by the county parcel maps.

北卡罗来纳州大地测量局（North Carolina Geodetic Survey）开发了名为"县界（County Boundaries）"的地理信息系统（Geographic Information System，简称GIS）数据集，该数据集经专业测绘，服务于北卡罗来纳州下辖100个独立县的规划、选址及影响分析工作。本文件展示了部分已完成边界测绘的县界，但绝大多数县界线段尚未开展测绘作业。此外，当县界与河流中心线重合时，部分边界无法实施测绘。请参考"线状县界（County Boundary as Lines）"数据集，通过"DESC"字段属性即可查询获取对应线段的来源信息。当前多数线段源自美国交通部（Department of Transportation，简称DOT）的县级地图，该地图原始数据来自美国地质调查局（United States Geological Survey，简称USGS），但可能已通过县级宗地地图完成更新。
