The NCDOT GIS Unit is pleased to announce release of the GIS Data layers on the GIS unit webpage specified below for Third Quarter 2017.  Future Quarter releases are tentatively scheduled for the following months:   November, February, May and August

1.      The NCDOT Rail Division data for Crossings and Track locations have been updated.  All rail feature classes are now bundled into one file geodatabase.  Shapefiles for each layer will still be available for download.

2.       The NCDOT Structure Locations which includes Bridge data has been updated and is now available for download.

3.      The Third Quarter 2017 Release of the Road Characteristics layer is now available which includes both System and Non-System routes.  The HighwayExit point feature class is included in the GDB.

4.      The Third Quarter 2017 Release of the Statewide System and Non-System Road Arcs and Statewide System and Non-System Road Routes is now available.

5.     The Smooth Urban Boundaries has been updated and available for download. 

6.      Metadata (information about the layer) is included for all layers available on this page and within the layer download and viewable through ArcCatalog.

7.      Data translation documents are available for NCRoutes, NCRouteArcs and NCRouteCharacteristics for download.  These documents translate the old field names to the new field name as well as provide their meaning, source contact and extent of each field.  These documents are similar to metadata but provide a more user-friendly, printer friendly read that can be accessed without ArcGIS software or downloading any of the feature layers.

For more information about available NCDOT data, please see document NCDOT GIS Unit Announcements.

Statewide System & Non-System Road Arcs

An Arc Layer for visual representation of the state road system where each arc/record is split at each road intersection. This is a digital file of the North Carolina Department of Transportation's Linear Referencing System that represents the routes and attributes of the NCDOT state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes, and Ramps and all non-state maintained and projected roads required for reporting purposes.

An Arc Layer for visual representation of a subset of road characteristics for the state road systems. Each arc/record is split where road characteristics change along a route. This is a digital file of the North Carolina Department of Transportation's road inventory database that represents a subset of road characteristic attributes of the NCDOT state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes, and Ramps. This layer also includes all non-state maintained and projected roads that are required for reporting purposes.
