The web uploader maintains the accuracy when you move the center around around (to a hilarious number of decimals).

I never noticed that it the Location Accuracy went up to fifteen decimals! Now that is what I call sub-atomic precision! Is it really necessary for the Location Accuracy to have that many decimals?
