UnitChangeTransformationClass

Creates a unit change transformation.

Description

The UnitChangeTransformation coclass implements a unit change method. It has no parameters but will convert the units in two different geographic coordinate systems (datums), for instance, between degrees and grads.

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.

Interfaces

Interfaces	Description
IClone (esriSystem)	Provides access to members that control cloning of objects.
IDatumTransformationInfo	Provides common properties for GeoTransformation and HVCompositeDatumTransformation
IGeoTransformation	Provides access to members that define a geographic (datum) transformation.
IPersist (esriSystem)
IPersistStream (esriSystem)
ISpatialReferenceAuthority	Provides access to the authority-related metadata for a spatial reference object.
ISupportErrorInfo (esriSystem)
ITransformation	Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on.
ITransformationGEN	Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. ITransformationGEN is generic version of ITransformation.
IUnitChangeTransformation	indicator interface for a unit change geotransformation (units are obtained from the constituent gcss.
IXMLSerialize (esriSystem)	Provides access to members that XML serialize and deserialize an object to/from XML.
IXMLVersionSupport (esriSystem)	Provides access to members that help in serializing an object to different namespaces (versions).
