Obviously not overkill if your mission requires this level of  
precision.  Sexigesimal notation is one simple and familiar way to  
implement a hierarchical coordinate mapping scheme to partition the  
high order and low order bits (or bytes or words or strings) for  
easier handling.  One size rarely fits all.
