(a) The system of plane coordinates that has been established by the United States Coast and Geodetic Survey for defining and stating the positions or locations of points on the surface of the earth within the State of California is based on the North American Datum of 1927 and is identified as the “California Coordinate System.” After January 1, 1987, this system shall be known as the “California Coordinate System of 1927.”

(b) The system of plane coordinates which has been established by the National Geodetic Survey for defining and stating the positions or locations of points on the surface of the earth within the State of California and which is based on the North American Datum of 1983 shall be known as the “California Coordinate System of 1983.”

(c) As used in this chapter:

(1) “NAD27” means the North American Datum of 1927.

(2) “CCS27” means the California Coordinate System of 1927.

(3) “NAD83” means the North American Datum of 1983.

(4) “CCS83” means the California Coordinate System of 1983.

(5)  “USC&GS” means the United States Coast and Geodetic Survey.

(6) “NGS” means the National Geodetic Survey or its successor.

(7) “FGCS” means the Federal Geodetic Control Subcommittee or its successor.

(8) “NATRF2022” means the North American Terrestrial Reference Frame of 2022.

(9) “PATRF2022” means the Pacific Terrestrial Reference Frame of 2022.

(10) “CCS2022” means the California Coordinate System of 2022.

(11) “CSRC” means the California Spatial Reference Center or its successor.

(12) “CSRN” means the California Spatial Reference Network, as defined by Chapter 3 (commencing with Section 8850), “Geodetic Datums and the California Spatial Reference Network.”

(13) “GPS” means Global Positioning System and includes other, similar space-based systems.

(14) “FGDC” means the Federal Geographic Data Committee or its successor.

(15) “NSRS” means the National Spatial Reference System.

(d) The California portion of the system of plane coordinates defined as the State Plane Coordinates System of 2022 (SPCS2022) as established by NGS and maintained by either NGS or CSRC shall be known as the “California Coordinate System of 2022.”

(e) The use of the term “State Plane Coordinates” refers only to CCS27, CCS83, and CCS2022 coordinates.
