A summary on the relationship between location accuracy and the number of decimal places in latitude and longitude degree values is available at http://en.wikipedia.org/wiki/Decimal_degrees#Accuracy (as an example, at the equator, degree values with 4 decimal places give about 11 metres accuracy, whereas 5 decimal places gives roughly 1 metre accuracy). -- GitLab
