Aides à la navigation, pratique de la navigation et construction des paysages maritimes en Atlantique du Nord-Est : quelques éléments de réflexion
Navigation without a chart or instruments depended on a pilot’s knowledge and ability to use the wind, the stars and the reading of the landscape to safely steer a ship to its destination. There has been a growing interest in navigation aids over the last ten years. Ongoing studies, only a few resul...
