Nahrwan 1934 / Iraq zone

Iraq - onshore. , accuracy 30.0 m, code 7033 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Derived by concatenation of parameter values published by IGN Paris from Nahrwan 1934 to WGS 72 at the Nahrwan SE Base station near Baghdad with DMA WGS 72 to WGS 84 parameter values. For more accurate transformation away from origin see codes 7008-7032.
