Provides access to members that control a set of geographic transformation operators (GT + direction).

Description
Use the GeotransformationOperationSet to project geometries having different geographic coordinate systems using the IGeometry::Project method. Use the IGeotransformationOperationSet methods to cache a set of Geotransformations in memory. This set is used by the software when projecting a geometry using the IGeometry::Project . If the geographic coordinate systems of the from/to spatial reference are different then the system looks in the GeoTranformationOperationSet to find a matching geotransformation. If no appropriate geotransformation is found, no geotransformation is applied.
When To Use
Useful when working with datasets that have multiple spatial references. Used in ArcCatalog to store any necessary transformations.
