The paper presents a study in occupational mapping, the focus of which is on combining locational data for early modern occupations with a contemporaneous town plan of Edinburgh, in order to study occupational distribution in the urban environment. By combining data from a 1635 tax roll with the corresponding section of the 1647 Gordon of Rothiemay map of Edinburgh, a new tool was formed for visualizing the distribution and physical patterns of urban occupations in the southeast quarter of Scotland's capital.
