    UTM question
    From: Greg R_
    Date: 2014 Mar 2, 19:03 -0800
    I've been getting up to speed on the UTM grid system, and have a question that I haven't been able to find an answer to: Since the northings are based relative to the equator, why do we need more than 2 northing zones (1 north and 1 south) for the non-polar regions?
     
    Since the eastings are based relative to a central meridian in a given zone, it makes sense that we'd need multiple ones of those to cover the entire globe - but the only reason I can see for having multiple north/south grid zone boundaries is as a "convenience" to make it easier localize an area to a given part of the world (?). Does anyone have a definitive answer to that one?
