This standard is intended to make centerline files more uniform and horizontally accurate. This will facilitate the sharing of a statewide seamless centerline spatial data layer. Adhering to these standards will insure the “usability” of the spatial data theme and its attributes by multiple entities. This standard will insure a consistent manner in which the centerline and/or attributes are collected. This will enable the data to be merged seamlessly, and transferable regardless of creator or jurisdictional boundaries. All data used in the creation of the Arkansas Centerline File shall meet these standards.

*Note: Throughout the remainder of this document ACF shall refer to Arkansas Centerline File. This includes the vector spatial data layer and its attributes. The ACF shall be composed of centerline files created from multiple sources and/or entities. Centerline shall include all clearly defined passages through which a standard vehicle may travel as well as driveways extending more than 500 feet and/or driveways containing two or more addressed structures.
