Creates a linear unit of measure.
Use the LinearUnit coclass to create a linear unit of measure to use with a projected coordinate system.
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.
|IClone (esriSystem)||Provides access to members that control cloning of objects.|
|IESRISpatialReference||Provides access to members that control the import/export operations components of a spatial reference system. This interface has been deprecated and IESRISpatialReferenceGEN should be used.|
|IESRISpatialReferenceGEN||Provides access to members that generate well known string (WKS) representations of spatial reference objects. IESRISpatialReference has been deprecated and IESRISpatialReferenceGEN should be used.|
|IESRISpatialReferenceGEN2||Provides access to members that generate well known string representations for spatial reference objects. The strings include authority metadata.|
|ILinearUnit||Provides access to members that control the properties of the linear unit.|
|ILinearUnitEdit||Provides access to members that control the properties of the linear unit.|
|IPersist||Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile.|
|ISpatialReferenceAuthority||Provides access to the authority-related metadata for a spatial reference object.|
|ISpatialReferenceInfo||Provides access to members that control the properties common to all components of a spatial reference system.|
|ISupportErrorInfo||Indicates whether a specific interface can return Automation error objects.|
|IUnit||Provides access to members that identify a linear or angular unit of measure within a spatial reference system.|
