ICompareCoordinateSystems Interface

Provides modified equality tests for spatial references.

Members

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