This drawing by Paul Sandby in the King’s Topographical Collection shows a surveying party at work near Kinloch Rannoch in Perthshire, Scotland. It is a more formal, stylised version of a similar scene now in the National Library of Wales and it might have been made to be engraved.
Sandby depicts the survey team on the eastern end of Loch Rannoch. A surveyor is using a theodolite next to a lady, an officer, his batman and two figures in highland dress in the foreground, while two assistants hold a chain to measure distances beyond. In the background, the hatched shading of the hillside recalls Sandby’s contemporary cartographic work.
