SPCS2022 Example Coordinates and Distortion Values
Last updated 6/2/2025
- Most example points are cities, towns, or other populated places; a small number are other identifiable features or the zone centroid (as indicated in the point name).
- Latitude and longitude are given to 9 arc-seconds (0.0025 degree) and ellipsoidal heights are given to 1 meter, and all of these exact values were used to compute SPCS2022 coordinates, distortion, and convergence.
- Linear distortion is given in parts per million (ppm) and is equal to the combined factor minus 1.
- SPCS2022 coordinate conversions can also be computed using the beta version of the NGS Coordinate Conversion and Transformation Tool (Beta NCAT).
| Zone code | Zone abrv | Zone name | Zone type | Point name | Latitude | Longitude east | Longitude west | Latitude (deg) | Longitude east (deg) | Longitude west (deg) | Ellipsoid height (m) | Northing (m) | Easting (m) | Northing (ift) | Easting (ift) | Point scale factor | Combined factor | Distortion (ppm) | Convergence angle |
