Abstract: A device (1) for evaluating a quality of measurements, the device (1) comprising a data store storing a set of n network nodes Ni, wherein said nodes store measurement data. The data store further comprises a set of l network links Lij, wherein each of the network links Lij connects one network node Ni with at least one network node Nj. The device (1) further comprises a quality evaluation unit (12) for calculating said quality, which quality evaluation unit (12) is adapted and structured to calculate a quality score Q as a function of said links Lij.
