Loadstone currently uses longitude and latitude values with up to 7
decimal places to the right of the decimal point. The 7th column is
responsible foraccuracy measured in centimetres. That is, the 7th column
determines an accuracy range between 1 and 9 CM. At very best today's GPS
receivers only yeild best accuracies affecting the 5th and 6th columns.
