The survey was executed in 1863 by John Parsons (Royal Navy) and the map engraved by John and Charles Walker. The two brothers, founding members of the Royal Geographic Society, were leading mapmakers and engravers working in London in the first half of the nineteenth century. They are known to have produced numerous charts for James Horsburgh and the Admiralty. Their company J & C Walker worked with the S.D.U.K. (Society for the Diffusion of Useful Knowledge) for whom they produced maps. They specialised particularly in maps of the British Empire and India. Furthermore they produced the maps for the Royal Atlas which ran to many editions.
The British Hydrographic Office was founded in 1795 by George III, who appointed Alexander Dalrymple as the first Hydrographer to the Admiralty. The first charts were produced in 1800. Unlike the U. S. Coast Survey the Hydrographic Office was given permission to sell charts to the public and they produced a great number of sea charts covering every corner of the globe. Most of the Admiralty charts produced by the Hydrographic Office delineated coastline as well as high and low water marks and record depth of water as established by soundings. In addition these charts included information on shoals, reefs, and other navigational hazards that plagued mariners across the world. Thanks to the innovations of Sir Francis Beaufort, who developed the Beaufort Scale of wind strength, the British Hydrographic Office became one of the leading producers of sea charts.
