Description:
Abstract:
The North Carolina Department of Transportation Developed the digital GIS 1:24,000 Roads from numerous state, county, and local governments to produce the most spatially acurate roads coverage for North Carolina. The base line work was digitized from USGS 1:24,000 Scale 7.5 Minute Topographic Maps. Any changes were updated using various scaled orthophotography. Originally the data was constructed using Bently's Microstation software and converted to ESRI ArcInfo Coverages. CGIA joined a database to the coverage provided by DOT allowing for a descriptive attribute in the coverage. The files have been clipped to the county boundaries.

Purpose:
This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

Native_Data_Set_Environment:
The data is in a current version of ESRI's ARC/INFO GIS software on UNIX, Sun Sparc workstations.


Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The roads were digitized from USGS 7.5 Minute Topographic Quads that met National Mapping Standards. Updates come from various sources and scales.

Logical_Consistency_Report:
Using ESRI's ARC/INFO GIS software, the dataset was built for arc and polygon topology using the "build" command. The data set was then cleaned with the "clean" command. Topology has not been edited since the last build or clean.

Completeness_Report:
These data represent transportation features, including roads, as determined by the US Geological Survey and the North Carolina Department of Transportation. Each feature is attributed with a feature description. Data represent all known roads at time of publication of sources, applicable to show at the 1:24,000 scale.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Transportation - NCDOT Roads (1:24,000) were based on the USGS 1:24,000 7.5 Minute dlgs from the Topographic Maps, which met National Map Accuracy Standards, and updates were made from various scaled orthophotographs. The data were supplied to CGIA who has made minor updates to the attributes.

Overview_Description:
Entity_and_Attribute_Overview:
An arc coverage depicting the locations of transportation features, including roads, as delineated by the US Geological Survey and North Carolina Department of Transportation. The arc attribute table (AAT) has data including to- and from- node identifiers, left- and righ-side polygon identifiers, length of linear feature in meters, and two internal identification numbers. There are three additional items, IGDS-LEVEL, FEATURE_DE, and FIPS. The IGDS_LEVEL attribute includes the microstation level assigned by DOT. FEATURE_DE describes the arc segment, i.e. two lane divided highway. The FIPS attribute is the Federal Information Processing Standard for the 100 North Carolina Counties.
