EPSG:4326 - WGS 84

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84, plus NAD83(CORS96) and NAD83(HARN), can be considered the same within the accuracy of the tfm. In USA only replaces tfm code 1900.

Attributes

Unit: metre

Geodetic CRS: NAD83(HARN)

Datum: NAD83 (High Accuracy Reference Network)

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: National Geodetic Survey

Revision date: 2007-04-20

Scope: Engineering survey, topographic mapping.

Remarks: State law defines system in US survey feet. See code 2878 for equivalent non-metric definition. Replaces NAD83 / SPCS for applications with an accuracy of better than 1m. Replaced by NAD83(NSRS2007) / SPCS.
