Description | Spatial | Attributes |
An Arc Layer for visual representation of a subset of road characteristics for the state road system. 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 some non-state maintained and projected roads that are required for reporting purposes. Data quality is tracked using the revision document fields (REVDOC_TYP_CD and REVDOC_NUM). Legacy data are coded as not verified. These data are updated on an ongoing basis to improve data quality and the revision document fields are updated accordingly. As new data are added the geometry and spatial location are verified with the most current information available.
For visual representation of the basic roads maintained by the North Carolina Department of Transportation.
1) This file should not be used for routing. 2) Please refer to the LRS Integration Guide (http://www.ncdot.org/it/gis/DataDistribution/DOTData/default.html) for definition of LRS related concepts and supported Linear Referencing Methods.
The data is current through September 2009 for roads changed by NCDOT Petitions and Municipal Agreements. It is current through the NCDOT 2007 HPMS Report for TIP changes.
The North Carolina Department of Transportation shall not be held liable for any errors in this data.

A unique identification number permanently assigned to a line feature between two known recoverable locations to represent a section of pavement. Spatial locations of linear events can be uniquely represented by combination of G1FTSEG, Beg_G1Fact, and End_G1Fact fields. Total G1FTSEG measure is calculated to the integer of one. This represents a percentage (0 - 1.000000) of the total length. G1FTSEG and its associated referencing points establish the LRS datum for NCDOT.Definition Source:
