amended to read as follows:
Section 1001. A. The systems of plane coordinates which have
been established by th e National Oceanic and Atmos pheric
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 points on the surface o f the
earth within the State of Oklahoma are hereafter to be known 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 must 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 1 927 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 i s used, it
shall be designated the "Oklahoma Coordinate Sys tem of 1927 South
Zone" or the "Oklahoma Coordinate System of 1983 South Zo ne".
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

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 meters 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 must be made to depend upon on
and conform to plane rectangular coordinate values for the
monumented points of the North American Horizontal Geodetic 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 plane 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
Coordinate System.
SECTION 3. AMENDATORY 60 O.S. 2021, Section 1004, is
amended to read as follows:

description extends from one into the other of the above coordinate

may must 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:
Section 1005. A. For purposes of more precisely defining 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 conic 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 coordi nates 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 defini ng the Oklahoma
Coordinate System of 1983, the following definition 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 Dat um of
1983, having parallels at north latitudes 35 degrees 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 th e parallel 35
degrees 00 minutes north latitude. This origin 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 degrees 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 th e
parallel 33 degrees 20 minutes north latitude. This origin is given
the coordinates: x = 600, 000 meters and y = 0 meters.
C. For purposes of more precisely defin ing the Oklahoma Plane
Coordinate System (OKPCS) the Oklahoma Plane Coordinate System must
be the State Plane Coordinate System of 202 2 (SPC2022)or its most

SECTION 5. AMENDATORY 60 O.S. 2021, Section 1007, is
amended to read as follows:
Section 1007. A. For the Oklahoma Coordinate System , of 1927
and the Oklahoma Coordinate System of 1983 the unit used to convert
feet to meters shall be the United States survey foot 39.37/12 feet
for each meter and defined as the U.S. survey foot.
B. For the Oklahoma Plane Coordinate System (OKPCS) the
international conversion value (1 International foot equals 0.3048
meters exactly) must be used and defined as foot.
SECTION 6. AMENDATORY 60 O.S. 202 1, Section 1008, is
amended to read as fol lows:
Section 1008. A. The use of the "Oklahoma Coordinate System of
1927 North Zone", or the term "Oklahoma Coordinate Syst em of 1927
South Zone" or "Oklahoma Coordinate System o f 1983 North Zone" or
"Oklahoma Coordinate System of 1983 South Zone " or "Oklahoma Plane
Coordinate System" (OKPCS) on any map, report of survey, or other
document shall be limited to coordinates based on the Oklahoma
Coordinate System as defined in this act.
B. Any legal description pre pared prior to November 1, 1990 the
most recent system of plane coordinates established by the National
