What is claimed is: 1. A method of displaying an aircraft taxiway and its associated identifier on a flight deck display, the method comprising the steps of: supplying data representative of taxiway segments, each taxiway segment at least partially defining the aircraft taxiway; processing the data to classify at least a portion of the taxiway segments as identified segments and non-identified segments; and rendering, on the flight deck display, at least a portion of the taxiway segments that define the aircraft taxiway, the rendered taxiway segments including taxiway segments classified as identified segments and non-identified segments, wherein: identified segments have the identifier associated with the aircraft taxiway rendered thereon, and non-identified segments do not have the identifier associated with the aircraft taxiway rendered thereon. 2. The method of claim 1, further comprising: determining if a taxiway segment defines a taxiway intersection, a taxiway intersection being a taxiway segment that adjoins three or more taxiway segments; and classifying at least a portion of the rendered taxiway segments that define taxiway intersections as non-identified segments. 3. The method of claim 2, further comprising: determining if a taxiway segment is an end segment, an end segment being a taxiway segment that adjoins only one taxiway segment; and if all of the segments that define the taxiway are defined as taxiway intersections, classifying as identified segments the taxiway segments that both (i) define taxiway intersections and (ii) are end segments. 4. The method of claim 2, wherein each taxiway segment comprises a plurality of vertices, and wherein the step of determining if a taxiway segment defines a taxiway intersection, comprises: determining if the vertices of the taxiway segment coincide with the vertices of at least three other taxiway segments. 5. The method of claim 4, further comprising: comparing the vertices of each taxiway segment to determine which taxiway segments adjoin one another. 6. The method of claim 1, further comprising: supply data representative of non-taxiway segments, each non-taxiway segment at least partially defining an aircraft pathway that is not an aircraft taxiway; determining if a taxiway segment adjoins a non-taxiway segment; and classifying the taxiway segments that adjoin a non-taxiway segment as identified segments. 7. The method of claim 6, wherein each non-taxiway segment is selected from the group consisting of one or more airport taxiways, one or more airport runways, one or more airport stopways, and one or more airport apron elements. 8.
