SECTION 1. AMENDATORY 60 O.S. 2021, Section 1001, is
amended to read as follows:
Section 1001. A. The systems of plane coordinates which have
been established by th e National Oceanic and A tmospheric
Administration/National Geodetic Survey, formerly the National Ocean
Service/National Geodetic Survey, formerly the United States Coast
and Geodetic Survey, or its s uccessors for defining and stating the
geographic positions or locations of point s on the surface of the
earth within the State of Oklahoma are hereafte r to be known and
designated as the Oklahoma Coordinate System of 1927 and, the ENR. H. B. NO. 3509 Page 2
Oklahoma Coordinate Syste m of 1983, and the Oklahoma Plane
Coordinate System (OKPCS).
For the purpose of the use of these systems 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,
Ellis, Garfield, Grant, Harper, Kay, Kingfisher, Lincoln, Logan,
Major, Mayes, Muskogee, Noble, Nowata, Okfuskee, Oklahoma, Okmulgee ,
Osage, Ottawa, Pawne e, Payne, Roger Mill s, Rogers, Sequoyah, Texas,
Tulsa, Wagoner, Washington, Woods and Woodward.
2. The area now included in the following counties shall
constitute the South Zone: Atoka, Beckham, Bryan, Caddo, Carter,
Choctaw, Cleveland, Coal, Comanche, Cotton, Garvin, Grad y, Greer,
Harmon, Haskell, Hughes, Jackson, Jefferson, Johnston, Kiowa,
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 G eodetic
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 o r location of
points within the state shall be known as the "Oklahoma Plane
Coordinate System" (OKPCS).
C. 1. As established for use in the North Zone, the Okla homa
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 Coo rdinate System of 1983
shall be named; and in any land description in which it is used, it
shall be designated the "Oklahoma Coordinate Sys tem of 1927 South
Zone" or the "Oklahoma Coordinate System of 1983 South Zo ne". ENR. H. B. NO. 3509 Page 3
3. As established for use, the Oklah oma 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).
SECTION 2. AMENDATORY 60 O.S. 2021, Section 1002, is
amended to read as follows:
Section 1002. The plane coordinate values for a point on the
earth's surface, used to express the geographic position or location
of such point in the appropriate zone of this system, shall consist
of two (2) distances expressed in U.S. Survey Feet and decimals of a
foot when using the Oklahoma Coordinate Syste m of 1927 and expressed
in meters or U.S. Survey feet and decimals of a meter or U.S. Survey
foot when using the Oklahoma Coordinate S ystem of 1983 and expressed
in International feet or meters and decimals of an International
foot or meter when using the Oklahoma Plane Coordin ate System
(OKPCS). One of these distances, to be known as the "x-coordinate"
(also known as "easting"), shall give the position in an east-and-
west direction; the other, to be known as the "y-coordinate" (also
known as "northing"), shall give the position in a n orth-and-south
direction. These coordinates shall be made to depend upon on and
conform to plane rectangular coordinate values for the monumented
points of the North American Horizontal Ge odetic Control Network as
published derived from the National Spatial Reference System (NSRS)
as defined and promul gated by the National Ocean Service National
Oceanic and Atmospheric Administration/National Geodetic Survey, or
its successors, and whose pl ane coordinates have been computed on
the systems defined in t his act. Any such station may be used for
establishing a survey connection to either Oklahoma Coordina te
System.
SECTION 3. AMENDATORY 60 O.S. 2021, Section 1004, is
amended to read as follows:
Section 1004. When any tract of la nd to be defined by a single
description extends from one into the other of the above coordinate
zone into other zones, the positions of all poin ts on its boundaries
may shall be referred to either one of the two zones, the zone which
is used being specific ally named in the description.
SECTION 4. AMENDATORY 60 O.S. 202 1, Section 1005, is
amended to read as follows:
ENR. H. B. NO. 3509 Page 4
Section 1005. A. For purposes of more precisely d efining the
Oklahoma Coordinate Syst em of 1927, the following defin ition by the
United States Coast and Geodetic Survey (now National Ocean
Service/National Geodetic Surv ey) is adopted:
1. The "Oklahoma Coordinate System of 1927 North Zone", is a
Lambert conformal conic projection of the Cl arke spheroid of 1866,
having parallels at north latitudes 35 degrees 34 minutes and 36
degrees 46 minutes along which parallels the s cale shall be exact.
The origin of coordinates is at the intersection of the meridian 98
degrees 00 minutes west of Greenw ich and the parallel 35 degrees 00
minutes north latitude. This origin is given the coordinates: x =
2,000,000 feet and y = 0 feet.
2. The "Oklahoma Coordinate System of 1927 South Zone", is a
Lambert conformal coni c projection of the Clarke spheroid of 1866,
having parallels at nort h latitudes 33 degrees 56 minutes and 35
degrees 14 minutes along which parallels the scale shall be ex act.
The origin of coordinates is at the intersection of the meridian 98
degrees 00 minutes west of Greenwich and the para llel 33 degrees 20
minutes north latitude. This origin is given the coordinates: x =
2,000,000 feet and y = 0 feet.
B. For purposes of more precisely defining the Oklahoma
Coordinate System of 1983, the following d efinition by the National
Ocean Service/National Geodetic Survey is ad opted:
1. The "Oklahoma Coordinate System of 1983 North Zone " is a
Lambert conformal conic projection of the North American Datum of
1983, having parallels at north latitudes 35 degree s 34 minutes and
36 degrees 46 minutes a long which parallels the scale shall be
exact. The origin of coordinates is at the intersection of the
meridian 98 degrees 00 minutes west of Greenwich and the parallel 35
degrees 00 minutes north latitude. This or igin is given the
coordinates: x = 600, 000 meters and y = 0 meters.
2. The "Oklahoma Coordinate System of 1983 South Zone " is a
Lambert conformal conic projection of the No rth American Datum of
1983, having standard parallels at north latitudes 33 degre es 56
minutes and 35 degrees 14 minutes a long which parallels the scale
shall be exact. The origin of coordinates is at the intersection of
the meridian 98 degrees 00 minutes west of Greenwich and the
parallel 33 degrees 20 minutes north latitude. This o rigin is given
the coordinates: x = 600, 000 meters and y = 0 meters.

most recent system of plane coordinates established by the National
Geodetic Survey (NGS) or its successor, or any continual use of
legal descriptions prepared pursuant to the provisions of this act
which have been reco rded or filed in official records within th e
State of Oklahoma, shall not be affected by this section.
