Behind The Lines – Mapping and Navigating Western Front Landscapes Through Spatial Technologies

A blogpost by Dr Keith Lilley (Queen's University Belfast) setting out an analytical framework for using Geographical Information Systems (GIS) as a 21st century spatial technology to explore how British trench maps of the First World War were made and used. The post is based on a paper given in Ypres on 5 November 2015 for the First World War Seminar Series organised by Gateways to the First World War and the In Flanders Fields Museum. Dr Lilley is the director of the Living Legacies 1914-18 AHRC public engagement centre.

“If the work of a general occurs in the space of an office, then the space of a battlefield ? physically expansive, perceptually elusive ? must necessarily be shrunk and flattened to the plane of a map”, Allyson Booth,Postcards from the Trenches (Oxford University Press, Oxford: 1996), 88.

The significance of the role played by maps and mapping in World War 1 cannot be underestimated. Whether small-scale geopolitical maps, or regional maps of particular sectors of combat, or larger scale detailed maps showing the disposition of gun emplacements, trench networks, and transport infrastructure, between 1914 and 1918 maps were very much a key part of the military machine of World War 1, for all those involved. There were of course also the many maps printed in newspapers of the time – with their over-scaled arrows and fronts – conveying to a war weary public, at home and abroad, the progress of battles and movements across the many fronts of this first global war.


From H. S. L. Winterbotham, ‘British Survey on the Western Front’, The Geographical Journal 53 (4) (Apr., 1919), pp. 253-271, page 263

According to one estimate, the British war effort alone saw 34 million topographic maps being produced between 1914 and 1918 for use on the Western Front. The process of producing these maps, and supplying them to the front, involved not just the Geographical Section of the General Staff (GSGS) but also the Ordnance Survey, both in England as well as in northern France. Creating so many new maps at such short notice was an enormous achievement in itself, and some indication of the contemporary recognition of this is indicated by the flurry of lectures given and papers published on aspects of survey and mapping work to learned bodies and institutions immediately after the war. The focus was especially on the difficulties of surveying in the field, as well as specialist areas of survey work such as trigonometrical survey, sound ranging and photogrammetry and aerial photography.

The cartographic innovations resulting from the GSGS operations during the war have been the focus of recent academic study too, particularly on sound-ranging and aerial photography, but less so on the field-survey work involved in creating a trigonometrical network. To redress this, a group of geographers, led by Prof Keith Lilley (Queen’s University Belfast), have focused on not so much the maps themselves but on what lay behind the lines they showed, the lines, that is, that composed the geographical information captured and conveyed by large-scale topographic maps – the lines of roads, contours, tramways and canals, and of course the trenches, both of allied and opposing forces, marked out in colour, bearing the names in many cases of those who inscribed the battlefield landscape with a sense of home as well as of humour. What lay behind the lines depicted on British and allied ‘trench maps’ of World War I was the work of men on the ground, surveyors, navigating in the field of battle with their theodolites, chains and plane-tables to sight, to triangulate, and to plot.


From H. S. L. Winterbotham, ‘Geographical work with the Army in France’, The Geographical Journal 53 (1) (July, 1919), pp. 12-23.

The trigonometrical networks that underpinned the large-scale ‘trench maps’, that British and allied forces used on the frontline, crucially depended on the field-surveyors’ work. To examine the geodetic accuracy of the maps that the British army made, and the effectiveness of the field-survey operations on the Western Front in 1917, twenty-first century spatial technologies can be used. To examine this, a pilot study has analysed a group of trench maps for the area of Messines (Mesen), near Ypres (Iepr), in Belgium. Analysing the map-series for one particular part of the frontline offers some otherwise unrecorded insights into the field practices of the surveyors, mainly from the Royal Engineers’ Field Survey Companies (FSCs), and reveals some of the material impacts that the battlefield had on these men and their work, their ability to navigate and survey, accurately, the mutilated landscapes of the Western Front.


The area examined to undertake this analysis lies to the south-east of Ypres, around Messines (Mesen), namely sheet 28SW of the GSGS2742 1:20,000 series. This particular sheet was chosen because it comprised an area that lay at the intersection of two inherited trigonometrical networks, the French and Belgium pre-war geodetic networks, as well as forming an area that saw mobility of the front line during 1916-18.


H. S. L. Winterbotham, ‘British Survey on the Western Front’, The Geographical Journal 53 (4) (Apr., 1919), pp. 253-271 at p. 259.

The approach taken to examine the accuracy of the Messines 28SW map editions was to use a Geographical Information System (ArcGIS) to digitise a series of map scans (rasters) of 28SW from the collection of the National Library of Scotland, thanks to the willingness of Chris Fleet, the library’s map curator. Each of the rasters was imported into the GIS, but the basis for analysing their cartographic accuracy used Open Source software called MapAnalyst. This calculates the relative compression or exaggeration of distances between points shown on an historic map with the same points calculated from modern geographical coordinates, which in our case were derived from those provided by Open Street Map (OSM).


Linking historic and modern maps using Control Points in a GIS: Identifying trigonometrical stations on 1:20000 scale mapping (28SW) and their corresponding reference points on Open Street Map.

The analysis procedure involved identifying a series of trigonometrical stations marked on the map and included in a British list of stations, known as ‘List of Trigonometrical Points in Part of N E France and Belgium, arranged alphabetically by 1/20,000 sheets, Volume I’ (General Staff, General Headquarters, P17/71, 600 4/17, reproduced in Peter Chasseaud’s Artillery’s Astrologers), which were used in surveying the area and providing a trigonometrical framework for sheet 28SW.


Sheet 28SW, 1 April 1917 edition: MapAnalyst distortion grid outputs, left with ‘exaggeration factor’, right without.

The results of the analyses using MapAnalyst reveals a very close match between the historic maps and modern mapping based upon common control points. This is the case for all seven revisions of sheet 28SW, between 1916 and 1918. Only when the MapAnalyst ‘exaggeration factor’ is increased are patterns of cartographic distortion seen to emerge from the ‘distortion grid’ outputs produced by the software. These outputs reveal geographical differences in levels of distortion across the map sheets, but not consistently in the same area across the seven map editions, suggesting that the MapAnalyst outputs are identifying changes over time in the underlying geodetic accuracy of the trigonometrical network used to create the maps of different survey dates for the Messines area, between 1916 and 1918. This is an interesting initial result that warrants further investigation, requiring field work today, in re-examining the locations of the trigonometrical stations used in the survey work, as well as broadening the area of the present study to cover other map sheets.

The cartographic accuracy of the maps deployed both on the frontline and behind the lines can be traced back to the survey successes in the field, in surveyors making their observations along the frontline. The maps, of 1:10,000 and 1:20,000 scale, resulting from their work, that showed the commanders and troops alike what was supposed to be there, derived from ‘spatial technologies’, innovations in surveying and map-making linking together remote sensing – aerial photographs in the latter stages of the war – with methods of ground survey. Through using Geographical Information Systems software, as well as modern geospatial data and analytical techniques, the impact the landscapes and battlefields had on the work of these surveyors, on their geodetic survey methods, and in mapping the British frontline, is revealed. Spatial technologies, then as now, expose the difficulties that were faced in mapping and navigating the Western Front.

The HMS Hawke art installation, which uses a net and rope framework, was created by local Sea Cadets. It includes 524 hand-made satin poppies – one for each victim of the sinking – which together form a unique memorial to the lost seamen.

The sinking of HMS Hawke had a big impact on Northern Ireland as 49 of the 524 sailors who died were from the Province.

Jennifer Hawthorne, the Housing Executive’s head of cohesion, said the project “has seen the local community take ownership of a gable wall which previously was a site of racist and sectarian graffiti”.

She added: “This unique artwork has achieved the groups’ aims of creating a poignant reminder of local people’s sacrifice during WWI. I commend the local community’s enthusiasm and wholehearted backing for this initiative.”

Angela Johnston from the Greater Village Regeneration Trust added: “Creating the ‘poppy wall’ gave members of the local community, many of whom have relatives with a service connection, a hands-on involvement in the project.”

Project designer of the art installation, Pete Bleakley, said: “The Donegall Road was one of WWI’s biggest suppliers of fighting men and the loss of HMS Hawke hit the Donegall Road and Greater Belfast hard.

Entwined Histories Showcase

2015-11-05 # EHS - Man on StageBrian Friel Theatre, Thursday 5th November

Living Legacies were delighted to attend the Entwined Histories' latest event, a celebratory showcasing of young peoples' self-produced dramas, detailing their responses to the Home Front during the war.

A culmination of several weeks of work, the dramas reflected young peoples' interpretations and understandings of the many, complex components of the Home Front.

2015-11-05 # EHS - Audidance

The evening was launched by the Cooperation Ireland team, and followed by a short talk from local historian Philip Orr, who has been at the heart of opening up new areas of focus for groups researching the war in Northern Ireland. Moving beyond militaristic understandings of the trenches is critical to broadening young peoples' knowledge of the total societal transformations caused by the war.

2015-11-05 # EHS - On StageThe productions, including representations of the Schoolhouse, the Shipyard, the Hospital and the Munitions Factory were enjoyed by a packed house, at the Brian Friel Theatre, part of Queen's Film Theatre. Supporting partners the Nerve Centre and Ulster Folk and Transport Museum have worked with the groups in developing their skills and knowledge over the duration of the project.

We were highly impressed by the commitment and talent of all participants and hope to continue our collaborative relationship in the future.

Education Minister launches new Wales at War platform

Welsh version

2015-11-02 # Wales = ST-CYRES001On Monday 2 November 2015, The National Library of Wales will launch a new Wales at War platform at St Cyres School, Penarth – a major, bilingual digital resource for schoolchildren, teachers and anyone with an interest in the First World War and its impact on Welsh communities.

Wales at War has been funded by the Armed Forces Community Covenant, the Heritage Lottery Fund (HLF) and the Department for Education and Skills in Welsh Government.  The project is led by the National Library of Wales, in partnership with the Royal Navy and schools in Wales.  The project has also benefitted from working closely with a range of partners, including the Armed Forces, the Royal Commission on the Ancient and Historic Monuments of Wales, the Archives and Records Council Wales and the Commonwealth War Graves Commission. 

Wales at War will engage young people in Wales in activities to develop their understanding of the history of the war using digital sources. The platform includes a timeline of the First World War with a distinct Welsh flavour, a Theatres of War section depicting where Welsh Service personnel fought, and a tool to engage young people and the general public in historical research by supporting them to create biographies of the names listed on their local war memorials. The project will raise community awareness of the memorials, drawing attention to any conservation needs, and will serve as a meaningful legacy of the First World War in Wales.

The project forms part of the Welsh Government’s Cymru’n Cofio Wales Remembers 1914-1918 programme of commemoration for the First World War taking place across Wales.

Launching the new platform, Huw Lewis AM, Minister for Education and Skills said:

"I am delighted to launch the new Wales at War platform - a project that will develop inclusive learning and encourage heritage activities as part of the commemoration of the centenary of the First World War in Wales.

"A key objective of our Cymru'n Cofio Wales Remembers 1914-1918 programme is to get our young people to take an active interest in the events and consequences of the First World War"

"This project, which has a distinct Welsh flavour, will foster greater engagement between schools, families, community groups and military organisations, and develop a collective biography of Wales at War.”

2015-11-02 # Wales = ST-CYRES036Richard Bellamy, Head of the HLF in Wales said:

"War memorials are important physical tributes to our War heroes.  As this excellent project demonstrates, there is a huge interest in marking the Centenary and exploring and sharing the heritage of the First World War, often in new and different ways.  Some of these stories are thought-provoking and inspiring; some are uncomfortable and create debate.  We want to encourage communities to explore these stories and I am really pleased that this project is reaching so many people."

Dr Jonathan Hicks, Headteacher St Cyres School, military historian and author added:

“The centenary of the Great War provides us with a unique opportunity to engage young people in the commemoration by teaching them the skills to enable them to learn more about how their community was affected by this devastating conflict. The 'Wales at War' app and website makes the best use of the technology youngsters already use on a daily basis to develop their research and collaboration skills.”

The website is available at and the app can be downloaded, for free, from the App Store, Google Play and through Hwb, the Welsh Government digital learning platform.

Wales at War is an important community outreach project that will foster greater collaboration between young people and communities to discover more about the impact of the war on life in Wales. By 2019, with your help, the project hopes to have collected the personal stories of the 40,000 or so Welsh men and women – soldiers, sailors, airmen, nurses and civilians – who lost their lives as part of the Welsh war effort.
