LONGITUDES Meaning and
Definition
-
Longitudes, in geography and cartography, refer to the imaginary vertical lines that run from the North Pole to the South Pole on the Earth's surface. These lines are used to measure and locate positions accurately, alongside the horizontal lines known as latitudes.
The concept of longitudes is based on the Prime Meridian, an arbitrary line that is designated as the starting point for measuring east and west distances. The widely accepted Prime Meridian is the line that passes through the Royal Observatory in Greenwich, London. It divides the Earth into two halves: the Western Hemisphere and the Eastern Hemisphere. The longitudes to the east are measured from 0° to 180° going eastward, while the longitudes to the west are measured from 0° to 180° going westward.
The main purpose of longitudes is to provide a standardized global referencing system. They enable accurate representation of spatial relationships, allowing precise measurement of distance, location, and navigation around the Earth. By using longitudes in conjunction with latitudes, one can determine the exact geographic coordinates of any point on the planet. Moreover, longitudes are essential for timekeeping, as they serve as the basis for the calculation of time zones globally.
Overall, longitudes play a crucial role in mapping and understanding our planet, facilitating navigation, determining time, and aiding global coordination.

Etymology of LONGITUDES
The word "longitudes" is derived from the Latin word "longitudo", which means "length" or "longness". It comes from the combination of the Latin words "longus", meaning "long", and "itudo", a suffix used to form abstract nouns. The term "longitudes" specifically refers to the measurement of positions east or west of a prime meridian, thus denoting the "longness" or extent of a location in that direction.
