Saturday 15 September 2018 - Local Hertfordshire meeting, Redbourn. organised by David Watt contact
Saturday 13 October 2018, Cambridge University Library, The Great Lines Project: Charles Hutton’s contribution to the invention of contours. Talk by Karen Rann.
The talk will focus on mathematician Charles Hutton who – whilst working for the Greenwich Royal Observatory – was tasked with computing the data collected by surveyors working on the mountain Schiehallion during an experiment to “weigh the world”. Hutton’s description of his subsequent map, and its calculations, were published by the Royal Society in 1778.
Although this manuscript map is missing, from his calculations Karen – working with a present-day mathematician – has been able to recreate a version of the missing map as well as ‘compare and contrast’ models of Hutton’s contours compared with modern OS altitudes.
The talk will also touch on some of the earliest manuscript maps to include isobaths, and cartographic depictions of the mountain Schiehallion (pre and post contours), in a bid to understand how ‘elevation’ has been depicted on maps through history.
Booking essential: For further information and booking, contact Bernard Anderson
Karen Rann is a freelance visual artist with a particular interest in space and place. Most of her work is research-based and a result of artist residencies. Usually the outcomes are in the form of installation, sculpture or performance, though now map-making is added to the list.


Saturday 11 June, Durham Record Office. This is a morning visit after which there is an opportunity to explore the historic city. The archivist has promised a fascinating display of local maps. Among them will be plans of coal seams and workings specially prepared for the owners of the mines involved and large-scale maps and plans of the surrounding area.
Monday 9 July, Chester Record Office – an afternoon visit to another historic city. Here we will see a display specifically aligned to CCS members and their interest. In addition to OS maps the Record Office holds examples of early maps of the county and more specialist material covering such areas as soil type and developments including the Manchester Ship Canal, the town of Crewe and New Towns at Warrington and Runcorn.
