Provides access to members that define a geographic (datum) transformation.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
Most methods and properties are inherited from ITransformation. Each geographic (datum) transformation also has a name, a 'from', and a 'to' spatial reference.
