UnknownCoordinateSystem CoClass

Creates an unknown coordinate system.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

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.
ICompareCoordinateSystems Provides modified equality tests for spatial references.
IConstructUnknownCoordinateSystem Provides method to define the properties of an unknown coordinate system.
IControlPrecision IControlPrecision interface.
IControlPrecision2 IControlPrecision2 interface.
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.
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.
IPersistStream (esriSystem)
ISpatialReference Provides access to members that control a SpatialReference.
ISpatialReference2 Provides access to additional members that control a SpatialReference.
ISpatialReference2GEN Provides access to additional members that control a SpatialReference. ISpatialReference2GEN is generic version of ISpatialReference.
ISpatialReferenceInfo Provides access to members that control the properties common to all components of a spatial reference system.
ISpatialReferenceResolution Provides access to members that control the resolution of a spatial reference.
ISpatialReferenceTolerance Provides access to members that specify the spatial and M tolerances of a spatial reference.
ISupportErrorInfo Indicates whether a specific interface can return Automation error objects.
IUnknownCoordinateSystem Indicator interface that identifies an Unknown coordinate system.
