1. (a)

   1. (1) The Arkansas State Land Information Board, now the Arkansas Geographic Information Systems Board, developed this document in order to support the legislative initiatives to establish the Arkansas Spatial Data Infrastructure, Arkansas Code § 15-21-501 et seq.
   2. (2) Spatial data layers are often stored digitally and accessed through a relational database management system (RDBMS).
   3. (3) Although the centerline file is a component of the Arkansas Spatial Data Infrastructure, the way in which people format and maintain it can differ.

   4. (4)

      1. (A) People often disagree on the way a particular spatial data layer structure should be organized.
      2. (B) This can pose problems in terms of sharing, locating, and extracting spatial data information.

   5. (5) It is intended that these standards will benefit the Geographic Information Systems (GIS) user communities in numerous ways, including but not limited to:

      1. (A) The National Map Program;
      2. (B) The TIGER Modernization Program;
      3. (C) E-911 applications;
      4. (D) Routing services; and
      5. (E) Location dependent services.
2. (b) The following standards in this part specifically speak to methodologies for creating a seamless statewide Arkansas Centerline File with address ranges that are shareable, are geocodable, and have a horizontal accuracy better than ten meters (10 m).

Codification Notes: This section, as promulgated prior to codification into the Code of Arkansas Rules, contained a footnote to 15 CAR § 280-102(a)(5)(A) as follows: "National Map Program - The U.S. Geological Survey (USGS) is committed to realigning and reinvigorating its topographic mapping activities to put truly current information into the hands of our customers, in a cost-effective way. Our vision is that, by working with partners, we will ensure that the Nation has access to and use of current, accurate, and nationally consistent base geographic information, including digital data and derived topographic maps. Our vision is documented in a report, The National Map http://nationalmap.usgs.gov/". This section, as promulgated prior to codification into the Code of Arkansas Rules, contained a footnote to 15 CAR § 280-102(a)(5)(B) as follows: "TIGER Modernization Program - The U.S. Census Bureau (Census Bureau) intends to issue a solicitation for full and open competition for services in support of the MAF/TIGER Modernization Program. The selected contractor will be expected to provide services for the MAF/TIGER Modernization strategic program objective number 1- Improve Address/Street Location Accuracy; Implement Automated Change Detection. The scope of the solicitation is addressed in the accompanying draft "Statement of Objectives" (SOO). The approach in fulfilling the Census Bureau's requirement will involve an acquisition process that is best explained in terms of the order events. http://www.census.gov/geo/mod/SOODraft2.pdf".
