User:Alua Koblan/Description of latitude and longitude

The latitude is specified by degrees, starting from 0° and ending up with 90° to both sides of the equator, making latitude Northern and Southern. The equator is the line with 0° latitude. The longitude has the symbol of lambda and is another angular coordinate defining the position of a point on a surface of earth.

Determination of latitude and longitude-latitude (i.e. the angle between the equatorial plane and the vertical line of the Earth) is determined by several methods depending on the height of the world pole at a given location. The most common of these are the measurement of the height of any star near the pole in its upper and lower climaxes; latitude is half the sum of the heights of the two climaxes of the star. Longitude is determined by the difference in local stellar (or local mean) time between two points. The time difference is determined by an alarm (radio telegraph, etc.) or by the transfer of a stopwatch with time adjustment at one of the two points. A time difference of 1 hour corresponds to a latitude difference of 15 °, one minute-15 '.
