EPSG:10480 DEPRECATED

NAD83 / TWDB GM

Selected transformation

Name: NAD83 to NAVD88 height (4)

Method: Geographic3D to GravityRelatedHeight (gtx)

Grid Files: g2003u04.bin

Remarks: Uses Geoid03 hybrid model. See information source for further information. Note: Source CRS is 2D, used in this application of the method as a pseudo-3D CRS.

Information source: National Geodetic Survey, http://www.ngs.noaa.gov/GEOID/

Revision date: 2015-11-25

Attributes

Unit: metre

Geodetic CRS: NAD83

Datum: North American Datum 1983

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Texas Water Development Board, https://www.twdb.texas.gov/

Revision date: 2023-09-28

Scope: Mapping and data analysis for Texas Water Development Board groundwater modeling.

Remarks: Not to be confused with the similar but different TxGIO (TNRIS) CRS, NAD83 / Texas Centric Albers Equal Area (CRS code 3083).

Area of use: United States (USA) - Texas.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
