AB In this paper we introduce the notion of rational Hausdor  divisor, we analyzethe dimension and irreducibility of its associated linear system of curves, and weprove that all irreducible real curves belonging to the linear system are rationaland are at  nite Hausdor  distance among them. As a consequence, we providea projective linear subspace where all (irreducible) elements are solutions to theapproximate parametrization problem for a given algebraic plane curve. Further-more, we identify the linear system with a plane curve that is shown to be rationaland we develop algorithms to parametrize it analyzing its  elds of parametriza-tion. Therefore, we present a generic answer to the approximate parametrizationproblem. In addition, we introduce the notion of Hausdor  curve, and we provethat every irreducible Hausdor  curve can always be parametrized with a genericrational parametrization having coe cients depending on as many parametersas the degree of the input curve.
