Name: Ain el Abd to WGS 84 (4)
Method: Coordinate Frame rotation (geog2D domain)
Remarks: Derivation is more precise, but no evidence that accuracy is better than Ain el Abd to WGS 84 (3). OGP recommends using Ain el Abd to WGS 84 (3).

Revision date: 2020-03-14
Unit: metre
Geodetic CRS: Ain el Abd
Datum: Ain el Abd 1970
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
