VerticalDatumClass Class

Creates a vertical datum.

Description

If a vertical coordinate system is gravity-related, it contains a vertical datum object. A vertical coordinate system can be ellipsoid/spheroid-based. In that case, it contains a horizontal datum object.

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.
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.
IHVDatum Indicator interface for a horizontal or vertical.
IPersist (esriSystem)
IPersistStream (esriSystem)
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 (esriSystem)
IVerticalDatum Indicator interface for vertical datums.
IVerticalDatumEdit Provides access to members that control the properties of a vertical datum.
