IESRISpatialReferenceGEN2 Interface

Provides access to members that generate well known string representations for spatial reference objects. The strings include authority metadata.

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

This interface is new at ArcGIS 9.3.

	Name	Description
	ESRISpatialReferenceSize	The number of bytes required to hold the persistant representation of this spatial reference component.
	ExportToESRISpatialReference2	Exports this spatial reference component to a buffer.
	ImportFromESRISpatialReference	Defines this spatial reference component from the specified ESRISpatialReference buffer.

Classes	Description
AngularUnit	Creates a angular unit of measure.
Datum	Creates a datum.
GeographicCoordinateSystem	Creates a geographic coordinate system.
LinearUnit	Creates a linear unit of measure.
Parameter	Creates a parameter.
PrimeMeridian	Creates a prime meridian.
ProjectedCoordinateSystem	Creates a projected coordinate system.
Projection	Creates a map projection.
Spheroid	Creates a spheroid.
VerticalCoordinateSystem	Creates a vertical coordinate system.
VerticalDatum	Creates a vertical datum.
