You should use metric it's easier since metric distances were based on a rough approximation of the circumference of the earth ;) 1 degree of latitude and at the equator, 1 degree of longitude ~= 100km, so every decimal place from there is an order of magnitude less. 0.1 ~= 10km 0.01 ~= 1km 0.001 ~= 100m 0.0001 ~= 10m 0.00001 ~= 1m 0.000001 ~= 10cm 0.0000001 ~= 1cm An inch was standardised based on metric :) 1 inch = 2.54cm exactly _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
