Creates a HARN-based transformation.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

The HARNTransformation coclass implements the HARN (HPGN) geographic (datum) transformation method. This is a grid-based method. The grids for forty-two states and two territories are available at ArcInfo 8.1.

See the IGridTransformation interface for the parameters.

Supported Platforms

Extended Error Information

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.
