Grid data for high precision conversion of geographic coordinates from the original NAD83 (1986) (EPSG:4269) to NAD83 High Precision Geodetic Networks (HPGNs) (EPSG:4152), also referred to as High Accuracy Reference Networks (HARNs). NAD 83 coordinates based on the HPGN/HARN surveys changed approximately 0.2 to 1.0 meter relative to the original NAD 83 (1986) adjustment.

Those files have been converted to NTv2 grids with the build_nad83_harn.sh script.

The GEOID99 model is known as a hybrid geoid model, combining gravimetric information with GPS ellipsoid heights on leveled bench marks. The GEOID99 model was developed to support direct conversion between NAD 83 GPS ellipsoidal heights and NAVD 88 orthometric heights.

It is superseded by later GEOIDxx models

GEOID06 is a refined hybrid geoid model for Alaska only.

GEOID06 converts between the U.S. ellipsoidal datum, NAD 83, and the U.S. vertical datum, NAVD 88. GEOID06 is built largely on the USGG2003 gravimetric geoid.

It is superseded by later GEOIDxx models

Source: converted from NOAA NGS .bin grids
Converter: build_g2009.sh
Format: GeoTIFF converted from GTX
License: Public Domain

The GEOID09 model is known as a hybrid geoid model, as it is modified from a gravimetric model to fit GPS ellipsoid heights on leveled bench marks. The GEOID09 model refers to a GRS-80 shaped ellipsoid, centered at the NAD83 origin. It supports direct conversion between NAD83 GPS ellipsoidal heights and NAVD88, GUVD04 and ASVD03 orthometric heights, and will support future vertical datums PRVD02 nad VIVD09.

GEOID12B is a hybrid geoid height model that can transform between the relevant vertical datum for each region to a NAD 83 ellipsoid height See https://www.ngs.noaa.gov/GEOID/GEOID12B/faq_2012B.shtml for more details.

The us_noaa_g2012bu0.tif and us_noaa_g2012bp0.tif grids are superseded by the us_noaa_g2018p0.tif and us_noaa_g2018p0.tif grids of GEOID18.

USA GEOID18 model: NAVD88/PRVD02 height to NAD83(2011)

Source: converted from NOAA NGS .bin grids
Converter: build_g2018.sh
Format: GeoTIFF converted from GTX
License: Public Domain

GEOID18 is intended for use with coordinates in the North American Datum of 1983 (2011) [NAD 83 (2011) epoch 2010.00]. It provides orthometric heights consistent with the North American Vertical Datum of 1988 (NAVD 88), the Puerto Rico Vertical Datum of 2002 (PRVD02), or the Virgin Islands Vertical Datum of 2009 (VIVD09).

GEOID18 covers CONUS, Puerto Rico, and the U.S. Virgin Islands and supersedes GEOID12B in these regions. GEOID18 does NOT cover Alaska, Hawaii, Guam and the Commonwealth of the Northern Mariana Islands (CNMI) where users should continue to use GEOID12B.
