1. A computer-implemented method for refining a zone location of a tracked object, the computer-implemented method comprising:

  • a) accepting, by a computer system including at least one computer, first location information derived from a first location technology;

    b) generating, by the computer system, a set of at least two candidate location zones using the first location, topology information and an accuracy range for the first location technology;

    c) for each of the at least two candidate location zones,1) establishing, by the computer system, a path from a previous location zone to the given candidate location zone, and2) storing, by the computer system and in association with the candidate zone, any location zones on the path;

    d) applying, by the computer system, at least one of (A) path-based candidate location zone elimination to each of the at least two candidate location zones, and (B) object-physics-based candidate location zone elimination to each of the at least two candidate location zones, to generate a refined set of at least one candidate location zone; and

    e) storing, by the computer system, the refined set of at least one candidate location zone in association with the tracked object.
