It's hard to misread and if you think instead of reading like a computer you will get it, stil it literally reads "nanometer", while Nautical Miles officially should abbr. NM http://en.wikipedia.org/wiki/Nautical_mile (they also say *M*, *Nm* or *nmi) *but I wouldn't use Nm either, as this is the official abbr. for energy (Newton metres =Joule). cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

No, a certain Martin K. has already reported the same. I'd say it depends on context; nm is often, if sloppily, used in aviation at least, but since sub-meter precision isn't required there, nobody will misread it.

The excellent book 'Map Addict' muses about the ultimate 1:1 map quoting from a story of 'exactitude in science' from 1946 as follows: "and so the College of Cartography evolved a Map of the Empire that was the same scale as the empire and that coincided with it point for point... succeeding generations came to judge a map of such magnitude cumbersome, and not without irreverence they abandoned it to the rigours of the sun and rain' I am sure that Potlatch 2.x will never be abandoned to the rigours of the sun and rain (even if Potlatch 1.x does meet that fait ;) ) A thoroughly recommend book. The only heath warning is that the guy loves the Ordnance Survey and can't bring himself to even mention OSM - he nearly does but clearly OSM is not a proper map to his mind. http://www.amazon.co.uk/Map-Addict-Mike-Parker/dp/0007300840 Great work Richard.

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 talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

For some reason last > time i calculated it I thought it was more. 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 0.1 ~= 1m 0.01 ~= 10cm 0.001 ~= 1cm An inch was standardised based on metric :) 1 inch = 2.54cm exactly ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

[OSM-talk] Potlatch 1.3
Hi all, I'm pleased to announce Potlatch 1.3 - a new version with one major improvement. Potlatch now lets you zoom in as far as zoom level 23. Previous versions only went up to z19, and even then with some loss of positional accuracy. This makes Potlatch much more suitable for tracing buildings, and other fine detail, from high quality aerial imagery like the NearMap imagery available in Australia. Don't forget that there's the option to 'Use thin lines at all scales' to make high-resolution work easier, too. A fair amount of the scaling code has been reworked to cope with this, so if you spot any mishaps on the way, reports at http://trac.openstreetmap.org/ are welcome as usual. This might be the last major revision of Potlatch 1.x - because work is now well underway on Potlatch 2, which is a complete rewrite with some whizzy new features. But more on that anon! cheers Richard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
