ISpatialReferenceFactory2 Interface

Provides access to members that create different kinds of spatial reference components. Note: the ISpatialReferenceFactory2 interface has been superseded byISpatialReferenceFactory3. Please consider using the more recent version.

Description

ISpatialReferenceFactory2 extends the ISpatialReferenceFactory interface and provides methods for accessing a variety of predefined geographic (datum) transformations and creating any kind of spatial reference (PCS or GCS) from its factory code.

Remarks

The CreatePredefinedGeographicTransformations and the GetPredefinedGeographicTransformations methods both return an ISet of all the possible geotransformations that ArcObjects can create. The SpatialReferenceEnvironment maintains ownership of the set returned by GetPredefinedGeographicTransformations. Neither this set nor its elements should be modified.  The Set and transformation elements returned by CreatePredefinedGeographicTransformations can be modified.
