SPCS2022 and NATRF2022 status: what surveyors should know in 2026

NGS preliminary SPCS2022 and NATRF2022 definitions are available but not yet officially adopted. Here is how to use them responsibly.

The short answer

As of 2026, NATRF2022, PATRF2022, SPCS2022, and NAPGD2022 remain preliminary NGS products. FGCS approval and Federal Register adoption are expected in late 2026 or early 2027. Production control work should continue on NAD83(2011) / SPCS83 / NAVD88 until official adoption.

What changed

The National Geodetic Survey is modernizing the National Spatial Reference System. NATRF2022 replaces NAD83(2011) as the geometric datum. SPCS2022 replaces SPCS83 with updated zone definitions on the NATRF2022 ellipsoid. NAPGD2022 replaces NAVD88 for orthometric heights.

These are not incremental tweaks. They are a new reference frame bridged through ITRF2020 with time-dependent Helmert parameters.

Why preliminary status matters

Preliminary definitions can change before adoption. Transformation grids between NAD83(2011) and NATRF2022 are still being finalized. NGS NCAT also does not provide final transformations between reference frames, so using preliminary coordinates for legally adopted control is risky.

FieldToCAD includes SPCS2022 zones behind a clearly labeled preliminary-reference toggle. Export is disabled for preliminary CRS targets. Default production work uses official NAD83(2011) State Plane.

What surveyors should do now

  1. Continue production work on NAD83(2011) / NAVD88.
  2. Experiment with SPCS2022 only in non-control workflows to understand the differences.
  3. Monitor NGS announcements for official adoption dates and final transformation tools.
  4. Never claim sub-millimeter accuracy on preliminary frame relationships.

FieldToCAD's approach

Preliminary zones display a caution badge and cannot be exported. Datum shifts between NAD83(2011) and NATRF2022 are unavailable in the native engine until official transforms ship, so FieldToCAD fails closed instead of letting preliminary CRS deliverables masquerade as production output.
