Geodetic CRS: Karbala 1979
Datum: Karbala 1979
Ellipsoid: Clarke 1880 (RGS)
Prime meridian: Greenwich
Data source: EPSG
Information source: Survey Directorate, Ministry of Water Resources.
Revision date: 2011-01-25
Scope: Transformation of coordinates at 0.3m level of accuracy.
Remarks: Derived at 95 stations mostly south of Baghdad but including 3 in Kirkuk-Erbil area. Maximum residuals 0.3m. May be used as a tfm to WGS 84 - see tfm code 5078.
Method: Geocentric translations (geog2D domain)
