EPSG:1754

Minna to WGS 84 (3)

Attributes

Geodetic CRS: Minna

Datum: Minna

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: OGP

Information source: Shell Petroleum Development Company

Revision date: 2008-11-07

Scope: Oil exploration.

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.

Method: Position Vector transformation (geog2D domain)

Area of use: Nigeria - onshore south.

Description: (-111.92, -87.85, 114.5, 1.875, 0.202, 0.219, 0.032)
