Karbala 1979 / Iraq National Grid

Iraq - onshore. , accuracy 1.0 m, code 5078 (default) [3]
Iraq - Basra area. , accuracy 5.0 m, code 15872 [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Parameter values from Karbala 1979 to IGRS (1) (tfm code 5077) assuming that IGRS is equivalent to WGS 84 within the accuracy of the transformation. Replaces Karbala 1979 to WGS 84 (1) (tfm code 15872).
