ISpatialReferenceAuthority Interface

Provides access to the authority-related metadata for a spatial reference object.


This interface is new at ArcGIS 9.3.


Name Description
Read-only property AuthorityName The name of the defining authority for this object.
Read-only property Code The code identifying this object relative to its authority. For the EPSG authority, this will initially be the WKID (factory code).
Method Define Defines the authority-related metadata properties for this spatial reference object.
Read-only property Version The version of this spatial reference object.
