EPSG:9905

Camacupa 1948 to RSAO13 (4)

Attributes

Geodetic CRS: Camacupa 1948

Datum: Camacupa 1948

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: EPSG

Information source: IOGP

Revision date: 2022-06-29

Scope: Oil and gas exploration and production.

Remarks: Parameter values taken from Camacupa 1948 to WGS 84 (9) (code 1326) assuming that RSAO13 is coincident with WGS 84 within the accuracy of the transformation. Equivalent to concatenation of EPSG:1326 and EPSG:8819.

Method: Position Vector transformation (geog2D domain)

Area of use: Angola - offshore blocks 1, 16 and 18.
