ICompareCoordinateSystems Interface

Provides modified equality tests for spatial references.

Members

	Name	Description
	IsEqualLeftLongitude	For geographic coordinate systems, this version of IsEqual includes considers their left longitude properties. Same as IsEqual for projected coordinate systems.
	IsEqualNoVCS	Compares spatial references without considering any vertical coordinate system that may be associated with the spatial reference.

ICompareCoordinateSystems.IsEqualLeftLongitude Method

For geographic coordinate systems, this version of IsEqual includes considers their left longitude properties. Same as IsEqual for projected coordinate systems.

Public Function IsEqualLeftLongitude ( _
    ByVal other As ISpatialReference, _
    ByVal compareVCS As Boolean _
) As Boolean

public bool IsEqualLeftLongitude (
    ISpatialReference other,
    bool compareVCS
);

ICompareCoordinateSystems.IsEqualNoVCS Method

Compares spatial references without considering any vertical coordinate system that may be associated with the spatial reference.

Public Function IsEqualNoVCS ( _
    ByVal other As ISpatialReference _
) As Boolean

public bool IsEqualNoVCS (
    ISpatialReference other
);
