Geodetic CRS: Ain el Abd
Datum: Ain el Abd 1970
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: MOMRA
Revision date: 2018-09-21
Scope: Transformation of coordinates at 5m level of accuracy.
Remarks: Nation-wide transformation. Accuracy given as 'several metres'. More precise national cellular transformation parameters were also determined. Software coded for these cellular transformations is available in MOMRA.
Method: Coordinate Frame rotation (geog2D domain)
Area of use: Saudi Arabia - onshore.
