This enumeration contains entries for some of the predefined projection and transformation parameters. Please see esriSRParameter2Type, esriSRParameter3Type, and esriSRParameter4Type for other predefined projection and transformation parameters. A value corresponds to the factory code used in the Projection Engine library.
