Description:
Abstract:
The North Carolina Office of State Planning, Geodetic
Survey in cooperation with the NC Center for Geographic Information
and Analysis, developed the GIS data set, Geodetic Control Points,
to identify points in North Carolina depicting horizontal and
vertical survey control locations as fixed by the NC Geodetic Survey.
Purpose:
This data was created to assist governmental agencies
and others in making resource management decisions through use
of a Geographic Information System (GIS).

>Revisions and updates to this layer include:
>7.) filename: gdc0803  Layer updated August, 2003.  29939 points.
>
>6.) filename: gdc1299  Layer updated December, 1999. Geodetic control
>points added and attribute z-value added. 28549 points. Data is in
>83, state plane, meters.
>
>5.) filename: gdc1298  The December 1998 update to this layer consisted
>of projecting the data from NAD83 datum, State Plane projection, units
>of measure feet TO: NAD83 DATUM, State Plane PROJECTION, UNITS OF MEASURE
>METERS.  This was done to comply with the NC Geographic Information
>Coordinating Council's "Statement of Direction for North Carolina
>Corporate Geographic Database Horizontal Reference, Datum and Unit of
>Measure".  This reprojecting was done in various ways depending on the
>data type and content.  Vector data was projected using the 'project'
>command in ESRI's Arc software and topology was cleaned and built based
>on  coverage needs.  Raster data was projected using ESRI's Grid module
>and various steps as applicable.
>
>4.) filename: gdc398   March 19, 1998 - Geodetic control points
>added. Number of points is now 28061 and data is in 83, stateplane,
>feet.

>3.) filename: gdc594  The May 1994 version has 26353 points and
>is in 83, stateplane, feet. (previously called nc.gdc594)

>2.) filename: gdc294  The February 18, 1994 file was in
>83, stateplane, feet. This file was reviewed and no changes

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Point attributes were supplied by the North Carolina Geodetic Survey.
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.

Process_Description:
The data for all 100 counties was sent to NC CGIA via e-mail.
This included the geodetic monument names with x/y coordinates
and z values in stateplane meters.  The 100 textfiles were joined
together, then read into an arc/info INFO file.
An ARC/INFO points coverage was generated in arcview using
add event theme.
