Parameters Name [optional] Name is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. Alias [optional] Alias is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. Abbreviation [optional] Abbreviation is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. Remarks [optional] Remarks is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. useage [optional] useage is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. Datum [optional] Datum is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. PrimeMeridian [optional] PrimeMeridian is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND. geographicUnit [optional] geographicUnit is a parameter of type VARIANT
To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND.
Use the Define method of IGeographicCoordinateSystemEdit to set the properties of a geographic coordinate system. A geographic coordinate system is defined (at minimum) by a name, an angular unit of measure, a horizontal datum, and a prime meridian.
