WGS84 bounds:
-72.87 -36.0
-69.77 -31.99

Attributes

Geodetic CRS: SAD69

Datum: South American Datum 1969

Ellipsoid: GRS 1967 Modified

Prime meridian: Greenwich

Data source: OGP

Information source: U.S. National Geospatial Intelligence Agency (NGA) Standard 0036 v1.0.0 of 2014-07-08.

Revision date: 2014-11-07

Scope: For military purposes only. Accuracy 2m in each axis.

Remarks: Derived at 6 stations. Along with transformations 6974 and 6976, replaces SAD69 to WGS 84 (5) (code 1868). Also used as a transformation from SAD69 to SIRGAS-Chile - see code 6968. Note: SAD69 adopted by Chile authorities only south of 43°30'S.

Method: Geocentric translations (geog2D domain)

Area of use: Chile - onshore between 32°S and 36°S.

Description: (-64.0, 0.0, -32.0, 0.0, 0.0, 0.0, 0.0)
