EPSG:26392

Minna / Nigeria Mid Belt

Selected transformation

Method: Position Vector transformation (geog2D domain)

Remarks: Derived at 8 stations across the Niger delta. Used by Shell SPDC throughout southern Nigeria onshore, delta and shallow offshore from 1994 and by Total in OPL246. Sometimes given with parameter values to greater resolution; values here are adequate.
