SPCS2022 Zone Definitions
Last Updated 6/1/2026
- Projection type abbreviations: LC1 (Lambert Conformal Conic, one parallel); TM (Transverse Mercator); OMC (Hotine Oblique Mercator, center)
- Terrestrial Reference Frame of 2022 (TRF2022) abbreviations: NATRF2022 (North American TRF2022); PATRF2022 (Pacific TRF2022); MATRF2022 (Mariana TRF2022); CATRF2022 (Caribbean TRF2022)
- All parameters are exact values, except for the North Carolina Zone (370001) false northing and easting in international feet, which are rounded to 0.001 ift.
- Per SPCS2022 Procedures, for zone abbreviations the state abbreviation can be separated from the zone part by a space or underscore. An underscore is used here to aid in filtering records.
