Method: Geocentric translations (geog2D domain)
Remarks: Derived by Brazilian Institute of Geography and Statistics (IBGE) in 1989 at Chua origin point. In use by Shell throughout Brazil. For use by Petrobras and ANP, replaced by tfm code 5882 from 1994.
Information source: Agencia Nacional do Petroleo (ANP) and IBGE resolution 23/89 of 21st February 1989.
Revision date: 2012-11-26
Unit: degree (supplier to define representation)
Geodetic CRS: SAD69
Datum: South American Datum 1969
Ellipsoid: GRS 1967 Modified
Prime meridian: Greenwich
Data source: OGP
Revision date: 2011-07-27
Scope: Geodetic survey.
Remarks: Uses GRS 1967 ellipsoid with 1/f to exactly 2 decimal places. In Brazil only, replaced by SAD69(96) (CRS code 5527).
Method: Geocentric translations (geog2D domain)
Area of use: Brazil - onshore and offshore. In rest of South America - onshore north of approximately 45°S and Tierra del Fuego.
Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
