Geographical code

A geographical code is a code which makes it possible to define (or to identify) a point, a zone, or an entity on the surface of the Ground.

Various systems of coding cohabit, but the systems can primarily be given by:

  • the way in which the code is created (Nombre, letter, mixture of both, other,…)
  • the portion of Earth which is concerned (the whole Earth, the ground, water, a Continent, a Pays,…)
  • the type of surface, zone, or coded entity (Country, county, Airport, Railway station, City,…)
  • according to whether the coded entity is a point or a surface
  • the period during which the code is valid
