Dennis, This may seem like a funny question, but what exactly is an ordnance map? I have looked at them, but cannot figure out why they are called that. As an old Marine, my mind tends to lean toward ammunition, although, I am aware that is ordinance. Another meaning would be a law - as a city ordinance. So what is an ordnance map?
