Real magnetic field data

Thanks for the fantastic global magnetic anomaly data and models. Is there anyway to use that data to plot the position of the poles e.g. the south magnetic pole has left Antartica and is 1/3 of the way to Melbourne? Another option is a vector map of the earths magnetic field from raw data to show the distortion around the the South Atlantic Anomaly which looks like it claimed another 3 satellites from Curtin Uni about two months ago. Any thoughts appreciated.
