Respective comparison functions are applied to the respective first field components (fp1, fr1) of the local influence fields (fp,fr) of the reference map (10) and the probe map (8) and to the respective second field components (fp2, fr2) of the local influence fields (fp, fr) of the reference map (10) and the probe map (8), yielding a first field component similarity value (sim1) and a second field component similarity value (sim2), respectively, and said first field component similarity value (sim1) and said second field component similarity value (sim2) are combined to a joint similarity value (Fsim) representing a difference in a mapping quality of the reference map (10) with respect to the probe map (8).",
