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
Revision date: 2018-08-29
Scope: Engineering survey, topographic mapping.
Remarks: Known in Kuwait as "KOC UTM". Used by KOC for engineering but not explorartion (see KOC Lambert, CRS code 24600). In Saudi Arabia, replaced by MTRF-2000 / UTM zone 38N (CRS code 8838).
Area of use: Kuwait - west of 48°E. Saudi Arabia - between of 42°E and 48°E.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
