Depot des Cartes et Plans de la Marine (fl. 1720 - present), often called the Depot de Marine, was a French hydrographic mapping organization founded in 1720. Much like the U.S. Coast Survey, the British Admiralty, and the Spanish Deposito Hydrografico, the Depot was initiated as a storehouse and distribution center of existing nautical and marine charts. Eventually the Depot initiated its on mapping activities in an attempt to improve and expand upon existing material. Some of the more prominent figures in the development of Depot were Jacques Nicholas Bellin and Riobert Bonne.
