The geographic coordinates are originally from the Department of Commerce publication of 1947: “Air-line Distances Between Cities in the United States” and from data supplied by the National Geodetic Survey and converted to the reference system of North American Datum 1983 using the National Geodetic Survey's NADCON program. The coordinates are determined by using the first city mentioned as the center of the urban area.
