Purpose: This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS). Supplemental_Information: >system filename: gdc file size = 3.2 mb > >Revisions and updates to this layer include: >7.) filename: gdc0803 Layer updated August, 2003. 29939 points. > >6.) filename: gdc1299 Layer updated December, 1999.

Logical_Consistency_Report: Using ESRI's ARC/INFO GIS software, the dataset was built for points using the "build" command. Topology has not been edited since the last build or clean. Completeness_Report: Points depicting horizontal and vertical survey control locations as fixed by the NC Geodetic Survey. Horizontal control markers based on North American Datum 1983 geodetic network and used as a base for mapping. Vertical control markers based on National Geodetic Vertical Datum 1929 geodetic network. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Points meet either the First-Order positional accuracy (not to exceed 1 part in 100,000) or the Second-Order, Class 1 positional accuracy (not to exceed 1 part in 50,000) for the National network of horizontal control.
