Description:
Abstract:
A GIS data set of Interstate routes, US routes, and select
state routes in North Carolina, to be used as a general
purpose roads layer, mainly for statewide plots and reference
maps. These routes were digitized from NCDOT County Road
maps.  Route 40 east of Orange County was added in 1993.
Purpose:
This layer was developed to show the general road network
in North Carolina, without having to depict detailed roads.
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:
>2.) filename: prds1298  The December 1998 update to this layer
>consisted of projecting the data from NAD27 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.
>1.) filename: prds93  (previously named nc.prds)
>Route 40 southeast of Wake County was added in 1992,
>and in Orange and Durham Counties in 1993.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes were taken from the DOT County Road Atlas and checked
using plots.  Attributes have been added as needed to assist in
map production. This layer was originally intended for internal
use, but was made available due to the demand for a general NC
road layer.
Logical_Consistency_Report:
Using ESRI's ARC/INFO GIS software,
the dataset was built for arc topology. Topology has not been
edited since the last build or clean.
Completeness_Report:
This data only shows Interstate routes, US routes, and select
state routes from the DOT County Road Atlas.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Roads match their source manuscripts to within a pen width.
This layer is not designed to be used for large scale plots,
or plots that depend on precise road location.

Process_Description:
The primary roads were selected and digitized from the DOT
County Road Atlas.  The arcs were attributed with road Ids
to enable labeling on plots.  This file is edited as needed
based on addition of new primary roads, or needed changes
in attributes to assist in plot making.
