Remarks
ZResolution resizes the existing grid about its center to achieve a target resolution of 1mm for low precision spatial references or 1/10 mm for high precision. This property provides finer control for specifying the resolution than does ISpatialReferenceResolution::SetDefaultZResolution. The default ZResolution is defined in standard units as 0.1 mm for high and low precision spatial references, or 1 mm for low precision spatial references. For ProjectedCoordinateSystems and GeographicCoordinateSystems, that default value is scaled to whatever units are associated with the spatial reference's VerticalCoordinateSystem property.
Use ISpatialReferenceResolution::ZResolution(False) to specify or retrieve the Z resolution in units defined by the vertical coordinate system.
The default value for ZResolution is NaN for a new spatial reference. If the ZResolution is not well-defined (ZResolution is NaN), calls to ISpatialReference::SetZDomain or ISpatialReference::SetZFalseOriginAndUnits will set the ZResolution to the minimum allowable value (2.0/zUnits). If the ZResolution was already defined, these methods will not alter the ZResolution.
