I doubt it, as they are updated from time to time, and I would guess 
they're less stable than the English names. Most likely some of those 
coordinates are typos that should be fixable. Most of those coordinates 
came from Shanks, who (I suspect) rounded them to fit whatever crude 
approximation his old database format was using.

Plus, people argue even about the coordinates! These can be just as 
political as the name.
