Aerial View Maps

A question about using maps and directions?

What is a "click"? For instance, if someone says "two clicks south of your location?" Are there any good books that someone would recommend on cartography/map interpretation?

1. a click is a kilometre its a military thing
2. My dear friend, Click is in deed a military term, but it refers to gun deflection in mils (rad divided by 1000). Anyway, you can search for Bowditch American Practical Navigator, releasable on line. I don't know the exact link, since I am an old times sailor. Best regards, Nikiforos
