Saturday 10th August, 10:30am, Highgate, London.

Enjoy another sociable CCS members’ map meeting at the excellent Woodman pub, 414 Archway Road, Highgate N6 5UA, see here.

Regulars will know it’s easy to reach, right next door to Highgate Underground (Northern line, High Barnet branch).  To avoid a lot of stairs, take the ‘Exit 3’ escalator up to Archway Road, turn right and the pub entrance is just around the corner in Muswell Hill Road.  For early arrivals, there’s even a small car park at the back, off Wood Lane which has plenty of free street parking lower down.
There’s no charge but please reserve a place – see below – and food and drink will as usual be at your own expense.  The Woodman’s prices are very reasonable for London and the menu, drink and service is excellent.  If it’s a warm day we could even have lunch outside.  We’ll begin at 10.30 (with hot and cold drinks available) and maps shown and discussed from about 11.00, lunch from 1pm (choose your own food and drinks – see their website), continuing after lunch until we run out of maps or steam!  
The theme this time will be 'Sporting London', to be run with any way you wish!   But don’t worry – it can be any topic you like if you can talk about it.  It doesn’t even have to be OS material, but of course please bring it if you have it.  If you have surplus maps for sale, or swaps, bring them along and you’ll be extra popular!
This event is Members only, to reserve a place however, please email Gerry Zierler at no later than Tuesday 6th August.


ONLINE TALK by Peter Vujakovič, Emeritus Professor of Geography, Canterbury Christ Church University

The Society's AGM was held in Grantham this year on Saturday 11th May. Details on this are in the April edition of Sheetlines.


ONLINE TALK BY KEITH LILLEY, Beneath the lines: mapping medieval townscapes using large scale OS maps

Tuesday 23rd April, 7.30pm. Zoom.

What lies beneath the lines on the map? The larger scale OS maps of Great Britain and Ireland show features of the historic urban landscape in great detail. In this talk, Keith Lilley explained the importance and significance of these cartographic features for mapping out the origins and evolution of our towns and cities. The lines on the map are a 'window' onto a much more distant medieval past, helping us to see how urban landscapes took shape on the ground so many centuries ago. Available to view from the CCS website here.



Thursday 14th March, 5pm, Zoom.

by A. Crispin Jewitt, author of Maps for Empire, 2nd edition.

Crispin Jewitt gives an illustrated talk about his brand new CCS publication, available next week.  First published in 1992 by the British Library, this new edition contains much new information and colour illustrations, describing the first 2000 sequentially numbered maps or map series issued by IDWO, TSGS, AND GSGS.  Available to buy from the CCS website here.



Saturday 23rd March, 10:30am.

Enjoy another sociable members’ map meeting at the excellent Woodman pub, 414 Archway Road, Highgate N6 5UA.

Thursday 28th March.

Hughenden, Buckinghamshire, is a Victorian mansion with earlier origins that served as the Prime Minister's country house, Benjamin Disraeli, 1st Earl of Beaconsfield. It is owned by the National Trust and open to the public. It sits on the brow of the hill west of the main A4128 road that links Hughenden to High Wycombe. HP14 4LA

At the start of WW2 there were few accurate Allied maps of Germany, and early RAF bombing raids were ineffective, leading to the need to set up a map-making operation. Hughenden was requisitioned by the Air Ministry from 1941-46 and, code-named "Hillside", the home of Air Intelligence 1b, the Air Ministry branch responsible for producing the target maps to plan and carry out every mission During the war, it was equipped with small-format Roland printing machines responsible for producing foolscap size RAF Target Maps. It also produced lattice overlays for aeronautical charts. "Hillside" moved to Bushy Park shortly after the war and became No. 2 SPC.

For more information on the day's programme of events, lunch and how to book, please see the flyer here.


ONLINE TALK, The Ordnance surveys of Kent of 1788 and 1795

Tuesday 23rd January 2024, 7:30pm. Zoom

Dr. Rob Wheeler presented what started off as a ramble through the OSDs but developed a focus on two rather beautiful maps of Kent, drawn at a time when the engraved one-inch was at most a bright idea that might or might not come to pass.

There will still be a few digressions en route, including what might be claimed as the earliest OS map that can be viewed online and an intriguing series of Specials that never happened.

View the recording here, streaming length: 1h 20m


ONLINE TALK, The Rise & Mapping of the Signpost.

Tuesday 5th December, 7:30pm. Zoom.

Richard Oliver explores how signposts came to be erected, and what we can learn about their numbers and distribution from early OS mapping. View the recording here, streaming length: 1h 05m.


Friday 17th November, 5pm. Drummond Hotel, Ballykelly, N. Ireland.

This is a one-day conference in November which will explore the local legacy of the Ordnance Survey around Lough Foyle.

The conference organised by the Binevenagh and Coastal Lowlands Landscape Partnership and Queens University Belfast will celebrate the end of the ‘Mapping Monuments’ community heritage project funded by the National Lottery Heritage Fund.

Since November 2021, volunteers have been working on the Mapping Monuments project, carrying out fieldwork and local research to find traces of the Ordnance Survey in the landscape. The conference will explore the project's findings, as well as see the launch of a new travelling exhibition about the Lough Foyle Baseline and its heritage.

Aimed at a wide audience, the conference will be opened by Joe Mahon and the day will be filled with hugely knowledgeable speakers - both academics and volunteers who have been working on the project.


SOCIETY MEETING, London in Rails & Rivers
Saturday 4th November, 10:30am. Highgate, London.

Bring along one or two maps of any of London’s railways or waterways, and tell us what you know about them, or ask others present to tell you!  All interesting maps are welcome, whether OS origin or not.


ONLINE TALK, The rise of Hagstrom's cartographic empire: early subway maps of New York City.
Wednesday 25th October

Peter Lloyd spoke to us live with many map illustrations. Showing how the new subway lines were integrated into the street map. Comparison with London's early Metropoltan Railway maps, which likewise had to show cut-and-cover underground lines within a dense city. Early New York mapmakers such as Hammond and Ohman followed the Metropolitan style of overprinting. It was Hagstrom that revolutionised the cartography by re-drawing the street map around the subway. And this is surely part of the reason that Hagstrom dominated New York street maps for a half a century, and remained a strong but waning force into the 1990s.
Peter Lloyd is a professional software engineer with a long-standing passion for collecting and studying maps of underground railway systems. He has embarked on a project to document the history of the New York City subway map.  In this project he has published Vignelli: Transit Maps (RIT Press 2012) and is now working on further volumes.

View the recording here, streaming length: 1h 03m



Saturday 8th July, 11am. Highgate London   

In what we hope will be the first of a series of live London meetings, CCS will be meeting at 'The Woodman' pub, right next to Highgate Underground station on the Northern Line. Bring a map (or two) and briefly talk about it, or just bring yourself and listen to others. The theme, appropriately enough, will be: London!  We will have our own area in the pub, starting at 11am.  A large screen is available via wi-fi if required. A good range of lunches and drinks will be available at reasonable London pub prices. There is no entry charge provided you pre-register.  Details of hope to reserve a place can be found in the electronic Newsletter that is sent to Members.

Saturday 13th May The first physical Annual General Meeting and map market for a few years, this is not to be missed. It is also the day after the Carto/Cymru Conference, see above, so another reason to attend. More details are in April's Sheetlines, please reply to Committee member Anne Taylor to confirm your attendance. We'd love to see as many attend as possible, to catch up with all things Ordnance Survey maps, and see some old friends too. 


  • This was led by CCS member John King, who promised a free map at the end of the walk!
  • Distance just over 2 miles, mainly on the flat but stairs will be involved, taking about 2 to 3 hours in total.
  • Maximum group size will be a maximum of 20, so please book in as soon as you can.
  • This is for Members only

The area of Vauxhall and Nine Elms developed in the 19th century with the coming of the railways into what had been a largely rural area. Alongside the railways there was also much industry. Significant changes occurred in the late 1960s and 1970s with the disappearance of the railway works and much of the heavy industry. What replaced these activities were light industrial units and warehousing including New Covent Garden Market. Another change began in the second decade of the 21st Century with the arrival of large scale apartment and flat buildings. The walk will reflect these changes and include the site of the Vauxhall Pleasure Gardens, 19th century housing developments with a 20th century twist, Vauxhall Park, the sites of two Royal Stations, the new Nine Elms underground station, the Sky Pool, the new United States embassy (technically we will actually be in the USA), the present day Nine Elms, a surviving country house and much, much more. 


This will be a talk by Dr John Peaty about Wellington’s army in the early 19th century 'Peninsular' war. Below is his abstract regarding the talk and context for reference. One of the major contributions to the liberation of Portugal and Spain from the French was the superb intelligence service developed by the British Army which enabled Wellington to know to a remarkable degree what was on the other side of the hill. In recent years British military historians have transformed our understanding of Wellington’s intelligence service in the Peninsular War. Urban, Davies and Romans have illuminated the work of code-breakers, agents and exploring officers. However, the contribution of British surveyors and map-makers to discovering and then depicting what was on the other side of the hill remains unappreciated - as does their contribution to recording Wellington’s campaigns and battles for posterity. This paper will examine the neglected work of Wellington’s surveyors and map-makers during and in the aftermath of the Peninsular War. It will show that men such as Broke, Sturgeon, Bell, Colleton, Staveley, Bainbrigge, Freeth and Mitchell made a major contribution to the success of Wellington’s operations and the winning of his victories by not only finding out what was on the other side of the hill but also by depicting it accurately and usefully. It will further show that such men made a major contribution to the study of the war by recording for history Wellington’s operations and victories accurately and usefully afterwards. Finally, it will show that such men rendered distinguished service in many fields and that, ironically, they are remembered today for things other than surveying and map-making in the Peninsula. 

DECEMBER ONLINE TALK Zoom Meeting #19, 12th December, 7:30pm 

The online talk before Christmas will be entitled 'Adding Railways to the Old Series' and will be by Dr. Rob Wheeler. The addition of railways was the principal cause of substantive revision to the one-inch Old Series. The manner in which it was done was far from uniform. This talk will explore some of the variation and consider whether it is appropriate to try to identify distinct styles. View the recording here, streaming length: 1hr 12m

ANNUAL GENERAL MEETING 2022, Saturday 20th August 2022 This occurred on Saturday 20th August, starting at 10:30am and finishing roughly an hour later. It was attended by just over 50 members. The minutes from the meeting will be collated and will appear in the December copy of Sheetlines. There wasn't a guest speaker this year, so no relavant recording is available.

 Zoom Meeting #17, Monday 6th June 2022 

Entitled "LOOK, THEY GAVE ME A MAP" by Ian Byrne. Not all maps were designed to be sold; some were given away for promotional reasons, by organisations as diverse as tourist boards, estate agents, bus companies, hotels, petrol stations and even tonic wine! Some were carefully designed to tempt the traveller to explore, while others look as if they were thrown together in 5 minutes. A few even used recognisable Ordnance Survey base mapping. At this Show & Tell we are inviting CCS members to bring along some favourites - good and bad - with the only restriction being that the first owner was not required to pay for them. They could date from any time in the past 150 years as, unlike many commercial maps with a cover price, these still seem to be produced in large quantities. 

NEXT MIDLAND GROUP MEETING, Tuesday 31st May 2022 

The next meeting will be on the subject of 'Tourist Maps' on Tuesday 31st May at 7:30pm at the Wall Village Hall in Staffordshire (Watling St, Lichfield WS14 0AW). Please contact Lez Watson if you'd like to attend, so he can monitor numbers. 


A local meeting will take place at Harmston, just south of Lincoln, on 25th April from 1:30 to 3:15pm, with tea and coffee from 1pm. The timing has been arranged to suit the arrival of the No 1 bus service both from Lincoln and from Grantham. Location will be Harmston Memorial Hall in School Lane (SK 970624). The format of the meeting will be a 'Show and Tell': those attending are invited to bring a map or two that they are prepared to show and to say a few words about. Those Members that are interested are asked to contact the Society Secretary (or telephone 01522 720692) indicating whether they plan to bring a map to talk about. It would be extremely helpful if as many responses as possible were received by 21st March so that the Hall booking can be confirmed. There will be a charge of £3 to cover Hall hire and coffee. There is no theme as such, but one of the maps will be a state of a Yorkshire 1st edition six-inch on which the contours were yet to be engraved; another will be one or more of the 1:500 sheets of Grantham. 

ZOOM MEETING #16, Tuesday 12th April 2022 

Rob Wheeler held a talk on Tuesday 12th April entitled "The Military Editions of the Six-inch Map". The War Department (WD) maintained plates for six-inch sheets which included detail which had been ordered not to be shown on sales editions. The WD also undertook revision of these sheets to standards rather different from those followed by the OS. The results can be highly informative, but they need to be used with caution. Visit the Zoom Meeting page for more details and the recording. 

NEW MEMORIAL TO MAJOR GENERAL WILLIAM ROY 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. Led 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.

 ZOOM MEETING #14, Monday 22nd November 2021 The subject was 'Milemarkers, sign boards & boundary posts and OS maps' and Dr. Richard Oliver did a talk, followed by a Q&A session. It was similar talk to ones previous that Richard has given to the 'Milestone Society' and new ground for those CCS members who aren't Milestone Society members, and probably new lights even for those who are. See the recording here.

 ZOOM MEETING #13, Monday 8th November 2021 The subject was 'Publication of the 25" by parishes: was Scotland treated differently?' and Rob Wheeler will do a talk, followed by a Q&A session. See the recording here. 

RETURN OF THE SOCIETY WALKS! Saturday 2nd October 2021 We're pleased to announce 'A walk around Waterloo and the South Bank' by John King. The walk will not be a cartographic meander but will include Waterloo Station, and some of its memorials, look down into the Waterloo and City line, the Necropolis Railway and the South Bank, particularly the remains of the Festival of Britain, plus many other points of interest. The meeting place is opposite Platforms 1 & 2 and the walk will take about 2 hours. We would ask for a maximum of 20 people on the walk, so if you'd like to attend, please mail the Visits Co-ordinator to book a place. There is no charge for the walk, just the good company of like minded people. 

NEXT MIDLAND GROUP MEETING, Tuesday 28th September 2021 The next meeting will be a 'Bring & Tell' evening on Tuesday 28th September at the Wall Village Hall in Staffordshire (Watling St, Lichfield WS14 0AW). Please contact Lez Watson if you'd like to attend, so he can monitor numbers.

 Monday 19th April 2021. Zoom meeting #11 'Aviation Maps Show & Tell' This was an open Show-and-Tell session hosted by Ian Byrne. See the recording here. 

Monday 22nd March 2021. 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 2021. 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. See the recording here. 

Tuesday 8 December 2020. 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 2020. Zoom Meeting #7, 'Quarter Inch Ordnance Survey Maps' Richard Oliver will run a Zoom session on the OS quarter-inch map. He intends to give a talk of half an hour or so on the basic development of the maps, but encourages questions from participants, and particularly any oddities that they may have found and know about. If you want to contribute, please contact Richard on 

Wednesday 11 November 2020. Zoom Meeting #6 'Errors & Omissions' This 6th meeting is to be chaired by Dave Watt on Wednesday 11th November at 7.30pm GMT on Zoom.   Those interested in participating should email Dave Watt at Dave invites all CCS members to attend whether as presenter or observer, and those presenting to email him with no more than five maps in either jpeg or .png formats.

Saturday 8 August 2020. 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 2020. 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....

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.
