Latitude is your position north or south of the Equator. Lines, or parallels, are drawn around the Earth at intervals. The North Pole is assigned the latitude 90Âº north and the South Pole latitude 90Âº south. Lines of longitude, or meridians, are drawn a little differently.
The map above shows how the NATO UTM system divides the earth into 60 longitude zones, each six degrees wide. The numbering begins at Zone 1 at 180 degrees west and proceeds eastward. To find the grid zone for any longitude: 1  Treat west longitude as negative and east as positive. 2  Add 180 degrees; this converts the longitude to a number between zero and 360 degrees. 3  Divide by 6 and round up to the next higher number.
