1. A method of modifying a geographic database comprising:

  • obtaining, from the geographic database, a set of geographic names associated with the same, or a portion of the same geographic feature,creating geographic-phonetic strings for the geographic names;

    determining a subset of the set of geographic names, the subset including geographic names that are both associated with the same, or a portion of the same, geographic feature and that have the same geographic-phonetic string so as to remove typographical errors and duplicative geographic names from the set of geographic names; and

    selecting a preferred geographic name for the subset and modifying the geographic database to preferentially flag the preferred geographic name so selected, as compared to the geographic names not so selected, wherein the determining of the subset uses the geographic-phonetic strings.
