Method: Geocentric translations (geog2D domain)
Remarks: Derived at 7 stations.
Information source: U.S. Defense Mapping Agency TR8350.2 September 1987.
Revision date: 1996-10-18
Unit: degree minute second hemisphere
Geodetic CRS: SAD69
Datum: South American Datum 1969
Ellipsoid: GRS 1967
Prime meridian: Greenwich
Data source: OGP
Revision date: 1995-06-02
Scope: Geodetic survey. Recommended coordinate axis representation for the human interface.
Remarks: Uses GRS67 ellipsoid with 1/f to exactly 2 decimal places. Precision of ellipsoid entry increased from 2 to 5 dp with change id 97.251. Error introduced if not using the truncated precision is 0 to 31mm.
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: DMSH.
