ISpatialReferenceFactory2 Interface

Provides access to members that create different kinds of spatial reference components.

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.

Classes that implement ISpatialReferenceFactory2

Classes Description
SpatialReferenceEnvironment Creates various spatial reference objects.

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.
