About creating a predefined projected coordinate system
The ISpatialReferenceFactory interface provides access for creating a projected coordinate system (PCS) in ArcGIS. You can return a single PCS with ISpatialReferenceFactory.CreateProjectedCoordinateSystem. Lists of the supported PCS are available in the esriSRProjCSType, esriSRProjCS2Type, esriSRProj3Type, and esriSRGeoCS4Type enumerations.
See the following code example:
[C#] private void CreateProjectedCoordinateSystem()
{
// Set up the SpatialReferenceEnvironment.
// SpatialReferenceEnvironment is a singleton object and needs to use the Activator class.
Type t=Type.GetTypeFromProgID("esriGeometry.SpatialReferenceEnvironment");
System.Object obj=Activator.CreateInstance(t);
ISpatialReferenceFactory srFact=obj as ISpatialReferenceFactory;
// Use the enumeration to create an instance of the predefined object.
IProjectedCoordinateSystem projectedCS=srFact.CreateProjectedCoordinateSystem(
(int)esriSRProjCSType.esriSRProjCS_NAD1983UTM_11N);
}
Private Sub CreateProjectedReferenceSystem()
' Set up the SpatialReferenceEnvironment.
' SpatialReferenceEnvironment is a singleton object and needs to use the Activator class.
Dim t As Type=Type.GetTypeFromProgID("esriGeometry.SpatialReferenceEnvironment")
Dim obj As System.Object=Activator.CreateInstance(t)
Dim srFact As ESRI.ArcGIS.Geometry.ISpatialReferenceFactory=obj
' Use the enumeration to create an instance of the predefined object.
Dim projectedCS As IProjectedCoordinateSystem=srFact.CreateProjectedCoordinateSystem(esriSRProjCSType.esriSRProjCS_NAD1983UTM_11N)
End Sub
