EPSG:8882

Camacupa 2015 to WGS 84 (11)

Attributes

Geodetic CRS: Camacupa 2015

Datum: Camacupa 2015

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: EPSG

Information source: University of Lisbon and Comissão Interministerial para a Delimitação e Demarcação dos Espaços Marítimos de Angola (CIDDEMA).

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: Used by CIDDEMA for delimitation of Angola's EEZ boundary. Derived by Univ. of Lisbon using 38 REPANGOL points. Average horizontal error 1m, vertical 3m; max radial error 6m. Application offshore differs from Camacupa 1948 to WGS 84 by approx 25m.

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Angola - onshore and offshore.

Description: (-93.799, -132.737, -219.073, 1.844, -0.648, 6.37, -0.169)
