England adopted the metric system in exchange for France adopting the Greenwich Prime Meridian. However, even those Prime Meridians weren't defined until the 17th century, which is a bit ahead of Qaiyore's advancement. (Unlike certain other anachronisms though, this is one which might have developed at any time for a variety of reasons.) > Prior to > that point, the English used the Greenwich meridian, the French used the > Paris meridian, and so on. > > As far as elevation goes, that's trickier.

So there are probably markers in Mirabalpur for both the Prime Meridian and base elevation. I wonder if Cormenaera has them as well? (Exquaestio is active in Mirabalpur and Cormenaera, but not in Thalcedon.) This is important because I was looking at some future developments for Exquaestio and it turns out for some things I'd like to do they need to define latitude, longitude, and elevation _down to the centimeter_. Latitude and longitude are no big deal, but elevation is giving me a headache.
