Remarks

SetDefaultXYResolution recalculates the maximum x and y coordinates for the domain of the spatial reference in order to achieve a target resolution of 1 millimeter for low precision ProjectedCoordinateSystems or 1/10 millimeter for high precision. For high precision GeographicCoordinateSystems, the target resolution is 1/10,000 of an arc-second and the low precision target resolution is 1/500 of an arc-second. For UnknownCoordinateSystems, the high precision target resolution is 1/10 millimeter and the low precision target resolution is 1 millimeter.  Resolutions are listed here in metric units but are converted to the units of the spatial reference by these methods.

Use the ISpatialReferenceResolution::XYResolution(False) property to specify the target resolution in units defined by the spatial reference.
