EPSG:8048

GDA94 to GDA2020 (1)

Attributes

Geodetic CRS: GDA94

Datum: Geocentric Datum of Australia 1994

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: GDA2020 Technical Manual (http://www.icsm.gov.au).

Revision date: 2018-04-20

Scope: Conformal transformation of GDA94 coordinates that have been derived through GNSS CORS.

Remarks: Scale difference in ppb where 1/billion = 1E-9. Derivation excluded Cocos, Christmas and Macquarie Islands but is applied there. See codes 8444-46 for equivalents using NTv2 method. See code 8447 for alternative including distortion model for Aus only.

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Australia including Lord Howe Island, Macquarie Islands, Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Norfolk Island. All onshore and offshore.

Description: (61.55, -10.87, -40.19, -39.4924, -32.7221, -32.8979, -9.994)
