Nahrwan 1934 / UTM zone 37N to Karbala 1979 / UTM zone 37N (12)

Attributes

Geodetic CRS: Nahrwan 1934

Datum: Nahrwan 1934

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: EPSG

Information source: Ministry of Oil 2008.

Revision date: 2015-02-06

Scope: Approximate transformation of seismic data acquired before 1985 to CRS used post 1985.

Remarks: May be emulated using geocentric translations from Nahrwan 1934 to Karbala 1979 of dX=-319, dY=185 and dZ=188m. Other maps give different values - see tfm code 7021.

Method: Cartesian Grid Offsets

Area of use: Iraq - between UTM 3470000mN and 3650000mN (approximately 31°21'N and 32°58'N) and between UTM zone 37 600000mE (approximately 40°04'E) and 42°E.
