If I'm doing it right, single precision float should be able to represent latitude and longitude to within about two meters.
yes, a precision of 2m is just not enough for showing buildings or streets.
If more precision than that is needed, you'll want to use "tr" to change periods (as well as commas) into spaces so that you get lines like: -112 3348783983763 36 1514008468736 100 Then filter for whatever range of integer latitudes and longitudes you're actually looking at. Then you should get 1 degree x 2^-24, better than a centimeter.
ok, scaling turns out to be a crucial problem to solve for the project. (what details to show at which levels of scaling...) have to figure that out first... thnks, marius.
