AB Given a rational projective parametrization P(s, t, v) of a rational projective surface S we present an algorithm such that, with the exception of a finite set (maybe empty) B of projective base points of P, decomposes the projective parameter plane as P^2 (K) \ B = U_{k=1^n} G_k,  such that, if (s0 :t0 :v0) ∈ G_k, then P(s , t  , v  ) is a point of S of multiplicity k.
