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, wherein both the subject dataset and the candidate dataset are stored as structured data in the first database and the second database, respectively, prior to identifying the candidate dataset.
