Provides access to members that control additional properties and methods for all geographic coordinate systems.

Product Availability

When To Use

Use IGeographicCoordinateSystem2 when you need to work with map projection horizons or transform between two geographic coordinate systems.

Members

	Name	Description
	Abbreviation	The abbreviated name of this spatial reference component.
	Alias	The alias of this spatial reference component.
	AngularConversionFactor	A factor to convert angular units from current GCS to destination GCS.
	Changed	Notify this object that some of its parts have changed (parameter values, z unit, etc.).
	CoordinateUnit	The angular unit of this geographic coordinate system.
	Datum	The horizontal datum of this geographic coordinate system.
	ExtentHint	Calculates a 360 degree longitude range from information in the specified envelope and the domain extent of the GCS.

	PrecisionImpl	An opaque reference to the precision information implementation for this spatial reference.
	PrimeMeridian	The prime meridian of this geographic coordinate system.
	Remarks	The comment string of this spatial reference component.
	RightLongitude	The greatest (right) longitude bounding a 360 degree range.
	SetDomain	The XY domain extent.
	SetFalseOriginAndUnits	Set the false origin and units.
	SetMDomain	The measure domain extent.
	SetMFalseOriginAndUnits	Set the measure false origin and units.
