1. A computer-implemented method for determining the location of a mobile electronic device, comprising:

  • obtaining an initial estimated location of the mobile electronic device determined using a location determination method (LDM);

    determining an existence of a cluster of multiple previously visited landmarks, the cluster of previously visited landmarks being located proximate to the initial estimated location, the cluster of previously visited landmarks including more than a threshold number of previously visited landmarks;

    calculating a distance to the cluster;

    selecting a landmark associated with the cluster based, at least in part, on the existence of the cluster of previously visited landmarks; and

    providing a known location of the selected landmark associated with the cluster as the location of the mobile electronic device.
