I did, but then I stuck the result (of 0.0110574 meters) into Google "0.0110574 meters to inches" to convert it into inches. I guess if I had thought about it 1.1 cm is also reasonable. 0.011 meters just didn't strike me as anything useful. I should have thought about it more. I believe my mistake the first time around was to use 1*10^-6 instead of 1*10^-7, because I came up with about 1/3 of a foot (which is approximately the length of 1*10^-6 degree of longitude in Tampa). I don't remember, because I came up with that several weeks ago, and only the end result of 1/3 foot stuck in my head. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
