Description

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.

    {

        // use activator class with SpatialReferenceEnvironment singleton

        Type factoryType = Type.GetTypeFromProgID("esriGeometry.SpatialReferenceEnvironment");

        IPrimeMeridian primeMeridian = spatialReferenceFactory.CreatePrimeMeridian((int)esriSRPrimeMType.esriSRPrimeM_Greenwich);

        IUnit unit = spatialReferenceFactory.CreateUnit((int)esriSRUnitType.esriSRUnit_Degree);
