Returns the IDatumTransform to use for conversions between source in and target in.
Transforms the given scale.
When transformation between a geographic coordinate system and a projected or local coordinate system, the geographic scale factor (see CoordinateSystem.GeographicScale) will be taken into account, in addition to the unit conversion factor.
Checks if this coordinate system transform is the identity transform.
This property only refers to the numerical identity of the transformation, i.e. output coordinates will be equal to input coordinates.
