PrimeMeridian.

fr : Actuellement, le méridien d'origine de la plupart des sytèmes géodésiques est voisin du méridien de Greenwich, qui passe par l'observatoire de Greenwich, en Angleterre. Jusqu'au début du XXe siècle, différents pays utilisèrent d'autres méridiens d'origine comme le méridien de Paris en France, le méridien de Berlin en Allemagne, le méridien de Tolède en Espagne ou le méridien d'Uppsala en Suède. Certaines cartes nautiques utilisaient le méridien de Ferro, correspondant à l'île d'El Hierro dans l'archipel des Canaries, afin d'obtenir une longitude positive pour toutes les terres européennes.
