Geodetic CRS: Corrego Alegre 1970-72
Datum: Corrego Alegre 1970-72
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: Petrobras.
Revision date: 2021-09-23
Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Remarks: Parameter values from Corrego Alegre to SIRGAS 2000 (2) (tfm code 6193) assuming that SIRGAS 2000 and WGS 84 are equal within the accuracy of the transformation. Used by ANP and Petrobras from February 2005, replacing use of tfm code 6192.
Method: Geocentric translations (geog2D domain)
