    In this paper we consider systems of vectors in a Hilbert space H\mathcal{H} of the form {gjk:j∈J, k∈K}βŠ‚H\{g_{jk}: j \in J, \, k\in K\}\subset \mathcal{H} where JJ and KK are countable sets of indices. We find conditions under which the local reconstruction properties of such a system extend to global stable recovery properties on the whole space. As a particular case, we obtain new local-to-global results for systems of type {Ang}g∈G,0≀n≀L\{A^ng\}_{g\in\mathcal{G},0\leq n\leq L } arising in the dynamical sampling problem
