System transformations for 2D linear systems are discussed and the invariants of such transformations are noted. This paper shows that it is zero coprime system equivalence which forms the basis of the generalisation of Rosenbrock's least order characterisation for the case of 2D systems. As such the invariants of 2D least order system matrices giving rise to the same transfer function can be given. (5 pages)
