In the MGRS (Military Grid Reference System) after being split into UTM zones, the earth is split into 100km x 100 km sections defined by two letters excluding I and O. these sections repeat and colom drop off while approaching the poles. essentially what I need it a way to mathematically predict the 100km^2 zones for increasing longitude (taking the flatting of the earth into account). Does anyone know haw to do this?

I switched to an IMHO more appropriate tag. I quickly perused the Wikipedia article. It sounded more like the basic square is 100 km x 100 km. When you write 100 km^2, people may think that you are referring to the area of the square, so it is a bit misleading. I won't edit that, because I may have misunderstood. –  Jyrki Lahtonen Jan 10 '12 at 14:11
Thanks, you're right though it should be that way. –  legacy Jan 10 '12 at 14:14
