Vertical Datum Transformations
Supports geoid model based vertical datum transformations across the United States using official hybrid geoid models from the NOAA National Geodetic Survey (NGS) to convert between ellipsoidal (NAD83) heights and orthometric heights referenced to NAVD88, with support for:
- GEOID18 (current national hybrid geoid model)
- GEOID12B and GEOID12A (previous generation models)
- Legacy geoid models such as GEOID09, GEOID06 and GEOID03
| Model | Technical Type | Grid / File Type |
|---|---|---|
| GEOID18 | Hybrid geoid model (ellipsoidal ↔ NAVD88 height conversion) | NGS geoid height grid (binary/ASCII distribution formats) |
| GEOID12B | Hybrid geoid model (ellipsoidal ↔ NAVD88 height conversion) | NGS geoid height grid (binary/ASCII distribution formats) |
| GEOID12A | Hybrid geoid model (ellipsoidal ↔ NAVD88 height conversion) | NGS geoid height grid (binary/ASCII distribution formats) |
| GEOID09 / GEOID06 / GEOID03 | Legacy hybrid geoid models (ellipsoidal ↔ NAVD88) | NGS geoid height grid (legacy formats) |
Source (Horizontal): State-level HPGN/HARN shift grids originate from the NOAA National Geodetic Survey’s High Precision Geodetic Network program. The files provided here are NTv2 conversions of the original NADCON-based datasets and are commonly distributed through the OSGeo PROJ data repository for use in modern transformation workflows between NAD83(HARN/HPGN) and NAD83.
Height conversion in the United States relies on hybrid geoid models developed and maintained by the NOAA National Geodetic Survey. Models such as GEOID18 and earlier GEOID releases provide the geoid–ellipsoid separation surface used to derive NAVD88 orthometric heights from NAD83 ellipsoidal coordinates and represent the national standard for GNSS-based elevation determination.
