Creates various spatial reference objects.
SpatialReferenceEnvironment is a singleton object. However, if you are working in a multi-threaded environment, each thread will have its own SpatialReferenceEnvironment. You should not pass information between the threads.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
|ISpatialReferenceFactory||Provides access to members that create different kinds of spatial reference components.|
|ISpatialReferenceFactory2||Provides access to members that create different kinds of spatial reference components.|
|ISpatialReferenceFactory3||Provides access to members that create vertical datums or coordinate systems.|
|ISupportErrorInfo||Indicates whether a specific interface can return Automation error objects.|
