The Hydrographic Department of the Admiralty was established by Order-in-Council in 1795 for the purpose of supplying up-to-date charts and hydrographic information to ships of the Royal Navy, in the first instance from a mass of undigested material accumulated at the Admiralty. In 1809 the Department also became responsible for supplying the fleet with chronometers. Through the nineteenth century the scope of the Department was steadily expanded until by the 1880s Great Britain became the first nation to offer a world coverage of charts and sailing directions on sale to shipping of all nations.
