This map was made by John Walker from the surveys completed by Captain Lloyd. Walker was a London-based mapseller, engraver, lithographer, hydrographer, geographer, draughtsman and publisher, who worked with both nautical charts and geographical maps. He followed in his father’s footsteps as an official hydrographer of the British East India Company, and was consequently tasked with the production of a wide range of navigation materials, including Belcher’s important map of Hong Kong and Carless’ exploratory map of Karachi.
