This large-scale map is divided into Jamaica's three counties: Cornwall, Middlesex, and Surrey, from left to right. It details the locations of sugar and coffee plantations, cattle farms, watermills, and windmills, as well as the boundaries of parishes. Additionally, it includes a table indicating the amount of cultivated and uncultivated land. 

James Robertson (b. c.1756, Scotland) arrived in Jamaica in 1778, and little is known of his life prior to that time. He worked as a surveyor, a profession considered lucrative in Jamaica during that period. According to his contemporary, John Stewart, “no map was ever, perhaps, more complete and comprehensive; and though such a work is not of much moment to the world in general, yet to the Jamaica proprietor it must prove peculiarly interesting.” Robertson was 54 years old when the map was published, and he likely recognized the significance of his work, as it is said that most Jamaican proprietors possessed a copy of it, both for its precision and artistry. Following previous maps, Robertson’s map named some estates after their owners.
