Method: Geographic3D to GravityRelatedHeight (gtx)
Grid Files: g2003u06.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
Unit: US survey foot
Geodetic CRS: NAD83
Datum: North American Datum 1983
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: National Geodetic Survey
Revision date: 2013-11-05
Scope: Engineering survey, topographic mapping.
Remarks: State law defines system in US survey feet. Federal definition is metric - see code 26978. For applications with an accuracy of better than 3 feet, replaced by NAD83(HARN) / SPCS.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: ftUS.
