Several techniques of increasing precision have been used to determine position and thereby enable the preparation of maps, promotion of commerce, and expansion of empires. Latitude, the angle of the plumb bob direction to Earth&#8217;s axis of rotation, is relatively easy to establish using the stars. \u00a0Longitude, location in the direction of Earth&#8217;s rotation, is both arbitrary and not as easy to determine.
