§ 60-1001. Adoption and description of official system of

coordinates.

A. The systems of plane coordinates which have been established

by the National Oceanic and Atmospheric Administration/National

Geodetic Survey, formerly the National Ocean Service/National

Geodetic Survey, formerly the United States Coast and Geodetic

Survey, or its successors for defining and stating the geographic

positions or locations of points on the surface of the earth within

the State of Oklahoma are hereafter to be known and designated as

the Oklahoma Coordinate System of 1927, the Oklahoma Coordinate

System of 1983, and the Oklahoma Plane Coordinate System (OKPCS).

For the purpose of the use of the Oklahoma Coordinate System of

1927 and the Oklahoma Coordinate System of 1983, the state is

divided into a North Zone and a South Zone.

B. 1. The area now included in the following counties shall

constitute the North Zone: Adair, Alfalfa, Beaver, Blaine,

Canadian, Cherokee, Cimarron, Craig, Creek, Custer, Delaware, Dewey,

Latimer, Leflore, Love, McClain, McCurtain, McIntosh, Marshall,

Murray, Pittsburg, Pontotoc, Pottawatomie, Pushmataha, Seminole,

Stephens, Tillman and Washita.

3. For the purpose of the use of the Oklahoma Plane Coordinate

System (OKPCS), the most recent system of plane coordinate and zone

designation that has been established by the National Geodetic

Survey (NGS), or a successor, that is based on the North American

Terrestrial Reference Frame of 2022 (NATRF2022), or a successor, and

the National Spatial Reference System (NSRS), or a successor, and

known as the State Plane Coordinate System (SPCS), or a successor,

for defining and stating the geographic positions or location of

points within the state shall be known as the "Oklahoma Plane

Coordinate System" (OKPCS).

Oklahoma Statutes - Title 60. Property

C. 1. As established for use in the North Zone, the Oklahoma

Coordinate System of 1927 or the Oklahoma Coordinate System of 1983

shall be named; and in any land description in which it is used, it

shall be designated the "Oklahoma Coordinate System of 1927 North

Zone" or the "Oklahoma Coordinate System of 1983 North Zone".

2. As established for use in the South Zone, the Oklahoma

Coordinate System of 1927 or the Oklahoma Coordinate System of 1983

shall be named; and in any land description in which it is used, it

shall be designated the "Oklahoma Coordinate System of 1927 South

Zone" or the "Oklahoma Coordinate System of 1983 South Zone".

3. As established for use, the Oklahoma Plane Coordinate System

(OKPCS) shall be named, and in any land description in which it is

used, it shall be designated the "Oklahoma Plane Coordinate System"

(OKPCS).
