1. A computer-implemented method for mapping geographic objects of a second database to geographic objects of a first database, the method comprising: identifying a subject geographic object of the first database comprising an identifier for which a corresponding candidate geographic object of the second database comprising the same identifier has not been identified, the subject geographic object corresponding to a subject dataset comprising at least two of the following: a descriptor of the subject geographic object; a geographic center of the subject geographic object; and a geographic shape of the subject geographic object; identifying, via comparison of the subject dataset corresponding to the subject geographic object to a plurality of candidate datasets each corresponding to a candidate geographic object of the second database, a candidate dataset comprising at least two of the following: a descriptor of a candidate geographic object that matches the descriptor of the subject geographic object; a geographic center of a candidate geographic object that matches the geographic center of the subject geographic object; and a geographic shape of a candidate geographic object that matches the geographic shape of the subject geographic object; and mapping the subject geographic object to a candidate geographic object corresponding to the identified candidate dataset.
