UPDATED 2 October 2021

The AGM took place by Zoom on Saturday 14 August at 10:30am and was attended by over 60 Members. It was followed by a talk from David L Walker on 'The Ordnance and the Hydrographic Service 1811-1843', which can be viewed from here.
Thank you to all those who attended, we hope to return to a live AGM next year in Aberystwyth on Saturday 14th May 2022. More details on this in the New Year.

NEXT ZOOM MEETING, Monday 22nd November at 7:30pm
The subject will be 'Milemarkers, sign boards & boundary posts and OS maps' and Dr. Richard Oliver will do a talk, followed by a Q&A session.
This will be a similar talk to ones previous that Richard has given to the 'Milestone Society'. This should be new ground for those CCS members who aren't Milestone Society members, and probably new lights even for those who are. Details of how to join in will appear in the Society eNewsletter.

The Charles Close Society are proud to be associated with this new memorial to Major General William Roy (1726 – 1790), whose work & leadership led to the creation of the Ordnance Survey in 1791.

Lead by Paul Doe and funded by London Borough of Richmond upon Thames and Civic Pride, the memorial marks the end point of the surveyed 'baseline' that Roy undertook in 1784. This forming the basis of triangulation in Britain and the backbone of Ordnance Survey maps today. According to Roy, the baseline measured 27,404.7 feet. In 1858 the Ordnance Survey re-calculated it at 27,406.4 feet on the basis of newer base measurements elsewhere in the country. This showed that Roy's original measurement was impressively accurate.

It is located here for reference:, so maybe pay a visit if you're in the area.

The Society has received a request from an author/historian who is in the very early stages of planning a book, tentatively called 'Beyond the Garden Gate'. It's a history of women's entry into the wild outdoors, until the C20 very much a masculine sphere. It features women mountaineers, environmentalists and botanists who were actively engaged in asserting women's rights to be present outdoors roughly 1900-1950.

The author would like to feature a woman mapmaker ideally who worked for the Ordnance Survey and understands a few women worked for the OS in France in WW1 helping produce trench maps. Then wonders if there were any others who actively mapped landscapes etc? The aim is for someone whose biographical details are available via memoirs/diaries etc so they can paint a picture of their life.

If anyone can help on this matter, please mail the author Sarah Lonsdale directly. Her previous published book for interest is 'Rebel Women Between the Wars: Fearless Writers and Adventurers' published in October 2020 by the Manchester University Press


RETURN OF THE SOCIETY WALKS! Saturday 2nd October at 11am

Monday 19th April, 7:30pm. Zoom meeting #11 'Aviation Maps Show & Tell'
This was an open Show-and-Tell session hosted by Ian Byrne. Further details on the content will be posted soon.

Monday 22nd March, 7:30pm. Zoom meeting #10 'The OS Half-Inch Map'
This lecture by Richard Oliver with a Q&A afterwards is an introduction to the Ordnance Survey half-inch map series, which several CCS members have been working on since even before CCS was formed! In Britain the series was introduced in 1902-3 in response to pressure from the army, and for the next 20 years they regarded it as the primary topographic map of the country. It went through several rethinks and redesigns, and arguably never achieved a ‘definitive’ form. In 1922 the army decided they liked the one-inch instead, and the half-inch had to survive or fall as a civil map. Efforts after 1930 at restyling and redrawing were frustrated first by the war and then by a lack of money, and the series came effectively to an end in Britain in the 1960s. In Ireland it had a different career: in the Republic it came to be the standard map of the country by the 1950s, and lasted, with some interesting changes of detail, until replaced by the 1:50,000 in the 1990s.

Monday 22nd February, 7:30pm. Zoom meeting #9, 'Railway Line Plans & their use of OS Material'
We have another Zoom meeting planned for the evening of Monday 22nd February at 7:30pm. This will be by CCS member Gavin Johns for an hour on 'Railway line plans and their use of Ordnance Survey materials'. It will contain some railway history; a major accident and railway operations and a ramble along the Teign valley and the Cambrian coast.

Tuesday 8 December, 7:30pm. Zoom meeting #8, 'Uncle Max Gill and his use of OS maps'
We welcome new CCS member Caroline Walker, author of newly-published biography 'MacDonald Gill: Charting a Life'. Caroline will give us a talk entitled 'Uncle Max Gill and his use of OS maps', with time for Q&As. Gerry Zierler will also add to the public transport aspect of Caroline’s talk with examples of use of OS mapping by London’s transport operators in the C20th.
Members wishing to attend please email and Zoom invitations will be sent to you soon.

Wednesday 25 November, 7:30pm. Zoom Meeting #7, 'Quarter Inch Ordnance Survey Maps'

Saturday 8 August, 12pm. Annual General Meeting
When we were obliged to cancel our plans for 9 May, we expressed the hope that it would be possible to hold an AGM in London on 8 August. As of mid-June, it appears doubtful that this will be permitted. Even were a physical gathering to be possible, many members may consider the risk of attending so large an indoor assembly, and of getting there by public transport, to be unacceptable. Accordingly, we have decided to follow the practice of most local authorities and to hold the meeting on-line, using Zoom, on 8 August at 1200.
The necessary link to join this meeting will be sent out by email to those members who have signed up for email alerts and in hard copy to all members with the next Sheetlines, which will come out somewhat in advance of its usual date and will include full AGM papers.

Tuesday 28 July, 12pm. Items at a Sotheby’s auction
An interesting couple of lots in a forthcoming Sotheby’s auction has been highlighted that might be of interest to the group. A partial set of 1 inch Old Series maps in 6 lovely cases, and a Survey of Jerusalem in 3 volumes, see the links below.
Fair prices, but lovely things they are....

Wednesday 13 May, Mercer’s Company Archive (City of London)

Wednesday 29 April, Tangmere Military Aviation Museum (TMAM), Chichester
The Defence Surveyors’ Association (DSA) has arranged a group visit to the Tangmere Military Aviation Museum (TMAM) which is situated just east of Chichester on the site of RAF Tangmere, one of the famous south-coast Battle of Britain airfields, which was also used later as a base for Special Operations Executive (SOE) Lysander aircraft.

The programme for the day will be similar to previous DSA events, with two or three presentations in a conference room and a tour of the Museum’s exhibits.
The cost is £8 per head, including tea/coffee breaks, but not including lunch. Attendance is limited to 45, hence early booking is recommended.

Local Group meeting, all members welcome, please contact David Watt at
Show and Tell on theme Miscellaneous ... one-offs, oddites and wierdos.

Don't Lose Your Way campaign from The Ramblers and then click on the box ‘JOIN THE SEARCH’.
Over 10,000 miles of paths across England and Wales could soon be lost forever, unless we come together to save them.
Shaped by our ancestors over centuries, our path network tells the stories of our history and our heritage and connects us to the landscape. But many paths are not recorded on the definitive map of rights of way, and if they're not found and added by the cut-off date of 2026 when the final map must be completed, they could be lost forever. To meet the deadline, this will be a huge undertaking and we need thousands of people to help.

That's why The Ramblers have launched Don't Lose Your Way to build a growing movement of people across the country to uncover and save generations of lost paths and hidden ways before it's too late.

They are also launching an exciting new tool. The Don't Lose Your Way online mapping tool splits the country into 150,000 1km squares and makes it easy to compare current and historic maps (from the NLS) side by side and find lost paths. They need your help to get as many people as possible mapping!

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.

New Maps from the Past Since 2008, the Charles Close Society has produced a series of classic maps, specially chosen for their rarity, aesthetic appeal, and significance within the story of the Ordnance Survey. Each map is produced in a folded Landranger format, reprinted in full colour and accompanied by notes. Maps from the past are distributed with Sheetlines at no extra cost to members and the sixth map, a facsimile of the one-inch Seventh Edition sheet 142 'Hereford' from 1949, was issued in 2016.
The Committee welcomes suggestions for future maps in the series, especially those which are rare and/or unfamiliar to members, attractive, and historically interesting.
Please send your idea to
You should include the following when making your suggestion(s):
Title of map (and series, if applicable)
