-66.33 -51.99

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 3m, 3m and 4m in X, Y and Z axes.

Remarks: Derived at 6 stations. Also used as a transformation from SAD69 to SIRGAS-Chile - see code 6970. Unlike IGM Chile, NGA extends use of this tfm to all Chile south of 44°S.

Method: Geocentric translations (geog2D domain)

Area of use: Chile - Tierra del Fuego onshore.

Description: (-79.0, 13.0, -14.0, 0.0, 0.0, 0.0, 0.0)
