Arkansas Administrative Code › Agency 192 - State Land Information Board (AKA. AR Geographic Information System Board) › Rule 192.00.19-001 - Revision of the Arkansas Cadastral Mapping Standard

Current through Register Vol. 49, No. 6, June, 2024
Introduction
The State Land Information Board, now the Arkansas Geographic
	 Information Systems Board, first developed this standard in 2004 order to
	 support the legislative initiatives to establish the Arkansas Spatial Data
	 Infrastructure (ASDI) (A.C.A. §
							15-21-504
	 ). Spatial data layers are often stored digitally and accessed through a
	 relational database management system (RDBMS). Although digital cadastral data
	 is a component of the Arkansas Spatial Data Infrastructure (ASDI), the ways in
	 which users format and maintain it can differ, and they may often disagree on
	 the way a particular spatial data layer structure should be organized. This can
	 pose problems in terms of sharing, locating, and extracting spatial data
	 information. It is intended that geospatial data standards will benefit
	 Geographic Information Systems (GIS) user communities through consistency and
	 efficiency of sharing the data.
Background and Purpose
As articulated in A.C.A. §
							15-21-504(f)(1),
	 the Arkansas Geographic Information Systems (GIS) Board,
" ...shall
	 define technical specifications and standards to use in the collection,
	 distribution, and reporting of spatial information as required by the State of
	 Arkansas Enterprise Architecture."
A.C.A. §
							15-21-501
	 further describes the purpose of the Arkansas GIS board in detail.
The
Arkansas Digital Cadastral Mapping
	 Standard
is intended to make digital cadastral data more uniform
	 and interoperable. This will facilitate the sharing of a statewide, seamless
	 digital cadastral spatial data layer. Adherence to this standard will enhance
	 the "usability" of the spatial data theme and its attributes by multiple
	 entities, ensure a consistent manner in which the cadastral parcel spatial data
	 and attribute data are collected or stored, and enable the data to be merged
	 seamlessly and become transferable regardless of creator or jurisdictional
	 boundaries. Digital cadastral maps enable the assessor to more efficiently
	 access parcel location and information, reveal geographic relationships that
	 affect property value, and provide a platform for the visualization of data
	 layers and analytical results. (2015.

	 Technical definition of system -- Marking of coordinates on ground.
(a) For purposes of more precisely
  defining the Arkansas Coordinate System 1983, the following definition by the
  National Geodetic Survey is adopted:
(1)
(A) The Arkansas Coordinate System 1983,
  North Zone, is a Lambert conformal projection of the North American Datum of
  1983 (NAD83), having standard parallels at north latitudes of thirty-four
  degrees fifty-six minutes (34 degrees 56' north) and thirty-six degrees
  fourteen minutes (36 degrees 14' north), along which parallels the scale shall
  be exact.
(B) The origin of
  coordinates is at the intersection of the meridian ninety-two degrees zero
  minutes west of Greenwich (92 degrees 00' west) and the parallel thirty-four
  degrees twenty minutes north latitude (34 degrees 20' north). This origin is
  given the coordinates: East equals four hundred thousand meters (400,000 m.)
  and north equals zero meters (0.0 m.); and
