ArcObjects Library Reference (Geometry)

GeographicCoordinateSystem CoClass

Creates a geographic 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.
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.
IESRISpatialReferenceGEN2	Provides access to members that generate well known string representations for spatial reference objects. The strings include authority metadata.
IGeographicCoordinateSystem	Provides access to members that control access to all properties of geographic coordinate systems.
IGeographicCoordinateSystem2	Provides access to members that control additional properties and methods for all geographic coordinate systems.
IGeographicCoordinateSystemEdit	Provides access to members that control the properties for a geographic coordinate system.
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)
IPRJSpatialReference	Provides access to members that control the import/export operations components of a spatial reference system. IPRJSpatialReference has been deprecated and IPRJSpatialReferenceGEN should be used.
IPRJSpatialReferenceGEN	Provides access to members that control the import/export operations components of a spatial reference system. IPRJSpatialReference has been deprecated and IPRJSpatialReferenceGEN should be used.
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.
ISpatialReference3	Provides access to additional members that associate a spatial reference with a vertical coordinate system.
ISpatialReference4	Provides access to additional members that control a SpatialReference.
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.
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.
ISRPersistStream	Provides access to methods for persisting precision information. Extends IPersistStream.
ISupportErrorInfo	Indicates whether a specific interface can return Automation error objects.

Remarks

The IClone::IsIdentical method is not implemented.
