The new Roy Military Survey Gazetteer

The British Library and National Library of Scotland are pleased to announce the availability of a new gazetteer which allows all the names on the Roy Military Survey Maps of Scotland (1747-55, British Library Maps CC.5.a.441) to be searched and browsed. Through the hard work of a team of volunteers over the last six months, all 33,523 names on the Roy Map have been recorded. The transcription workflow has also recorded related or nearby names from the Ordnance Survey 1st edition mapping from a century later in order to help searching and provide additional context for the Roy names. The results are of huge value for local and family historians, placename researchers, as well as all those interested in the landscape of 18th century Scotland. As well as being able to find any name on the map, it is also possible to now generate distribution maps of particular name elements, or dynamically view all of the names in a particular area. The Gazetteer can also be downloaded in accessible formats for onward use and research.

The Roy Military Survey Map is surely one of the most significant and attractive maps of Scotland. It was a distillation of military intelligence, planned in the wake of the defeat of the Jacobites at Culloden in 1746, and surveyed at the same time as the brutal ‘pacification’ of the Highlands. The English military commanders in Scotland during the Jacobite Rebellion of the ‘45 had been 'greatly embarrassed for want of a proper Survey of the Country' and something needed to be done about it. The decision to place the Survey in the hands of a young civilian from a small village near Carluke, William Roy - who had no military surveying experience, and who was then in his early 20s - was a surprising one, even if it turned out to be an inspired and successful decision. Over the next eight years, until the mid 1750s, the whole of the Scottish mainland was surveyed at the detailed scale of one inch to a thousand yards, or about 1:36,000. For many parts of the Scottish Highlands, it is the most detailed and informative map that survives for the entire 18th century, and for all areas, the only standard topographic map prior to the Ordnance Survey mapping in the 19th century. As part of the King George III Topographical Collections, it has always been a treasured item within the British Library’s holdings, and fortunately more recent digital technologies have allowed its wider availability online, as well as transcription projects like this.

Our project to record all of the names on the Roy Map was based on the long interest in the map from those hunting for the existence and location of particular places, especially for local and family history purposes. Place name researchers have also regularly examined the Roy Map as a key documentary source for the 18th century. Many of the textual entries on the map allow other types of research too, confirming the location of things like mills, kirks, castles and estate grounds. Many significant elements of the pre-Improvement landscape - such as the smaller kirk towns and cottar towns, as well as things like moors and commonties - are clearly shown too. But libraries lack the manpower for major gazetteer recording projects, and although machine-learning and artificial intelligence continue to make strides, we felt that the only way to achieve our objective at present was by gathering a volunteer group as part of a crowdsourcing project.

In January 2022 we asked for volunteers to help with three new map transcription projects, and were thrilled (and relieved!) to find over 650 people signed up to take part. We were able to create the interfaces for recording the names using the open-source web-mapping software behind the NLS maps website, and this was helpful, as we continued to change and update these interfaces in response to feedback. We also set up an online discussion forum for participants, which has been very heavily used - 142 members, and over 210 posts over a 5 month period. Successive phases of the project revised and checked the initial names, and their related Ordnance Survey names, so that all of the names were reviewed and edited several times over. The success of the project owes itself very much to these volunteers, who have not only put in several months of hard work, but also continued to suggest changes as we went along to improve the results. As with all website projects, we also have the ability to keep revising and correcting names in response to feedback - the Gazetteer will become ever more perfect over time! Although we have just now launched the Gazetteer, some minor revision work is still ongoing, and we are happy to receive suggestions and corrections from the wider community.

Would William Roy have approved? We certainly hope so - as the “father” of what became the Ordnance Survey, he would have fully understood the value of national initiatives to gather geographic and topographic information. He would surely have delighted in the detailed scrutiny which his ‘magnificent military sketch’ was still getting, over 250 years after its original creation. That said, he might feel puzzled and worried about all the tartan, now very visibly on sale only a stone’s throw from where his Military Survey was drawn in Edinburgh Castle!

George III's maps and views: 32,000 images released on Flickr Commons

In October 2020 we released 17,000 images of maps and views from George III’s Topographical Collection on the images-sharing site Flickr Commons, which seems to have kept you busy. 

Well, from today, you can find an additional 32,000 images, comprising George III’s collection of atlases and albums of views, plans, diagrams, reports and surveys, produced between 1550 and 1820. These have been uploaded to Flickr with a Public Domain attribution for you to search, browse, download, reuse, study and enjoy.

Vrients Low Countries
Jan Baptista Vrients, Descriptio Germaniae Inferioris, 1602. 118.e.16.

 What have we added?

So much! Here are some highlights:

Complete cover-to-cover digitisation of major 16th, 17th and 18th century atlases by Joan Blaeu (lots of Blaeu), Jan Janssonius (again, lots of Jansson), Abraham Ortelius (a few Ortelius atlases here), Jodocus and Henricus Hondius, John SpeedMoses Pitt, Thomas Jefferys, Mary Anne Rocque, Nicolas Sanson, Pierre du Val, Herman Moll and others. Most have never been released in their entirety anywhere online before.

Albums of topographical views by artists such as John Webber, Robert Havell, Thomas Daniell and John Clerk.

Multi-sheet maps in loose or bound format including Turgot’s plan of ParisMorgan’s map of London, Peter Andre’s Essex, Fry & Jefferson’s Virginia, Pratt’s Ireland and Müller’s Bohemia.

Albums of 16th century prints and drawings of Roman architecture and antiquities assembled by Cassiano dal Pozzo. 

Many manuscript atlases including work by Carlo Fontana, Francesco Basilicata's 1612 survey of Crete, and two Kangxi atlases of China.

 How can you access them?

Via Flickr

The first release of 17,000 images - the collection of individual maps and views,  was released in one big bundle. It made sense to release this disparate group of items this way, but we appreciate that searching Flickr for specific images is not especially easy (see below, Explore, for a solution. Of course, it can be interesting to browse if you are not sure where you want to end up!).

Responding to your feedback, this second release has organised the bound atlases and volumes of prints into separate albums. The images within the albums retain the order in which they are encountered in the physical copy.  The titles of the albums are made up of the constituent volume's author, title, date and shelfmark, so we hope this will make the searching experience a good one. Batching into 500 or fewer images will make downloading easier for you too.

Via Explore

Every image on Flickr is accompanied by metadata which includes a link to the corresponding British Library Explore catalogue record. The links are reciprocal, meaning that you can search for specific items via Explore (key tip: add ‘George III’ to your search term (free text) in order to bring up only maps and views in the K.Top). When you have found the record for the item you require (look for the record for the volume or album, rather than the record for an individual map of view within that volume, which will not contain the digital link), select ‘I Want this’ and then ‘View Digital Item’, which will take you to the relevant image(s) on Flickr.

 Anything else?

We hope you will find everything to your liking. However, as with any large release of digital images, you may encounter the odd hiccup for which we apologise. Please get in touch with us and we’ll do our best to put it right.

Although Flickr Commons now includes pretty much everything from the Topographical Collection, there is a small handful of images which we have still to release. We're working on it!

In due course, all of this content will become available on the British Library’s own dedicated Universal Viewer, while a dataset of the entire collection will also be released on the British Library's research repository.

We are keen to hear how you are using it so please let us know and provide feedback via social media @BLMaps or by emailing us at [email protected].

Finally, a word of thanks to our colleagues at British Library Labs for their tireless perfectionism and dedication in developing these Flickr pages.

Now off you go and explore.

One-Fifth of the World's Surface

One-Fifth of the Earth’s Surface is a digital audio-visual, multimedia web experience by artists Hakeem Adam and Maxwell Mutanda. Commissioned by Abandon Normal Devices and York Mediale, the work is, as the title suggests, an exploration of the ‘power of water as a dynamic and fluid archive’ with the Atlantic Ocean its main subject.

The British Library has been involved in providing resources for the project, and a number of maps from the Topographical Collection of George III, digitised and released as Public Domain on Flickr have been included in the exhibit, along with sound recordings from the Library’s Sound Archive.

I was interested to see how maps would be deployed in the piece. There are a multitude of maps that show the Atlantic Ocean, its coasts, and the infinite network of rivers and arteries which feed it (a number of maps along these lines, created by Adam in Mapbox, are embedded in the artwork). Maps not only visualise the Atlantic Ocean, but influence how it is navigated, experienced and memorialised, and this role of maps is also explored in One-Fifth of the Earth’s Surface.

The online exhibition is split into sections, including: Memory, Analogue of Rivers, Ports, Navigation and Cartography, each constructed using various audio-visual elements that build, overlap and occasionally interrupt. Navigation is not straightforward, almost, at times, like fighting against the waves. Early maps appear in a number of places, particularly in the Archive section where they form part of the artists’ research materials. It is immersive, unpredictable digital art.

The creative potential of maps and mapping is limitless, and there is no better time to use them when so many are available from opened-up archives, where traditional and digital techniques are within reach, and when there is so much they can be used to say.

Maps on the British Library's Online Gallery: update

The British Library’s ‘Online Gallery’ was first created in 2004, and over the years a number of galleries containing thousands of maps have been added to it, from the earliest Ordnance Survey maps to Tudor mapping. Each map has its own page with a full description and cataloguing information, a downloadable image, and a larger – though not downloadable - ‘Zoomify’ image.

However, at the end of last year, Adobe ceased to support Flash player and Zoomify became inoperable. For anyone who likes to zoom into a map (about 100% of people who use maps), this is an issue. This is what we’ve done to solve the problem. Firstly, we’ve removed the Zoomify links from the map pages in order to avoid confusion (you can still download a -full-size’ though under 1 MB image for your own use).

For the more heavily used galleries, we’re happy to say that the maps are available – and downloadable - from Wikimedia Commons.

For the Ordnance Surveyor Drawings, the still-active Zoomify link will redirect you straight to the same map on Wikimedia.

The Goad fire insurance maps are all there also.

Only 2,500 George III Topographical Collection maps and views were on the Online Gallery, but you can now enjoy 18,000 of them on Flickr, with even more on the way (you can link through to these images via our catalogue Explore the British Library).

And don’t forget that all of the Online Gallery maps are also available on our Georeferencer (have a go at Georeferencing a few).

The Georeferencer
Map collections on the Georeferencer

Have a look at this and this blog post to discover where else you can discover British Library maps online for free.

For the other galleries such as the Crace Collection of maps of London, we are working to find a way of getting the larger images to you (you can still download smaller images from the existing pages). In due course also, these maps will all make their way onto the Library’s Universal Viewer.

Thanks again for using the Library’s online map resources. And if you get the chance, do drop us a message about the interesting things you’re doing with them.

A medical man maps Kent

Mapmaking is a highly exacting profession, as the scrutiny of current pandemic mapping demonstrates. Yet the fascinating thing about mapmaking is that everybody is capable of creating a map, and throughout history 'amateur' mapmakers have brought something new to the table.

Christopher Packe (1686-1749) was a local physician based in the area of Canterbury in Kent, who during his 'many otherwise tedious' medical  journeys around the area was struck by the similarities between the  landscape, features and processes of the natural world and those of the human body. Most notably, and unsurprising for a physician, the synergy between hydrology (specifically streams and rivers) and the flow of blood through the arteries and capillaries. As I mentioned in a previous post, there’s a strong history of thought positioning the human body as a microcosm of the universe. Packe's 1743 Philosophico-Chorographicall chart of East Kent is the Gunther von Hagens of maps.

Looking closely we can see the tremendous series of lines of thousands of tiny watercourses connecting to streams and thence to rivers, flowing out into the sea. So many of them, in fact, that we might be looking at a map of the English Fenland.

Maps_k_top_16_24_11_tab_end detail 3

That's not all that Packe's map shows. Shading and spot heights communicate the relative heights above sea-level which Packe measured using a barometer. This has led to the map being described as the world's first geomorphological map. And finally there is the series of concentric circles demarking the map's co-ordinate system. These emanate from Canterbury and the cathedral, from which  Packe used a theodolite to survey the county and form his aesthetic and philosophical vision (see Michael Charlsworth for an in-depth study). 

Maps k.top 16.32.2

Packe wrote a treatise in support of his work, and even produced a 'specimen' sample of the larger map six years earlier, a sort of taster which was presented to the Royal Society. A copy of the specimen is in the Topographical Collection of George III, published 'at his own expense.' Indeed, Packe put so much into his map that it is possible to imagine life in it, the culmination of a creative act. Something, if you will forgive the further analogy, created from the heart.

Pandemic maps: science, size and simplicity

2020 has certainly been a year for maps, though not one for which any of us will feel grateful. I’m referring to the proliferation of often doom-laden public maps illustrating the spread (and receding – more of this please) of Covid-19 across the UK. Throughout the year, interactive maps have appeared on online media outlet pages, and most prominently, maps have featured along with graphs and charts in daily government briefings into the official response to the virus.

Data visualisations have played an important role in keeping the public informed, and for demonstrating the scientific evidence behind the adoption of measures to combat the pandemic. Occasionally the quality of data visualisation has not been to standard. Professor James Cheshire of UCL Geography has written about this, providing some cardinal rules such as ’explain your working’ and ‘keep it simple.’

This latter rule has been well understood by the makers of public maps for centuries. Before the computer screen, maps had to work hard in order to be legible and intelligible by large groups of people from potentially large distances away. From the 1840s in the UK, large maps were specifically designed with bolder lines and reduced information in order to function, for example, in large elementary school settings.

UpdateCruchleyScaleExample

Large maps were also used as backdrops for large gatherings and meetings. Remember those?

Sifton-Praed Ltd., 'The German scheme of Mittel Europa.' London, 1916.
This large map of 1916 showing the projected Berlin-Baghdad Railway, almost 3 metres wide, was used as the backdrop for public lectures on subjects such as 'Why Germany Wanted War.' Sifton-Praed Ltd., 'The German scheme of Mittel Europa.' London, 1916.

If you want your map to be seen and understood by a lot of people, make it as clear as possible.  Of course, this isn't always practical: nobody wants to be accused of ‘dumbing-down’. And there is no getting away from the fact that geography is complicated and maps can be misleading, particularly when it involves mapping people who are neither static nor evenly spread. Thus the map of the UK divided into counties or regions and coloured by numbers of Covid cases per 100,000 people is falsely reassuring: large, rural and comparatively Covid-free counties dominate visually over smaller, more concentrated and consequently more affected urban areas (tools such as inset maps, and more arresting colours and tones, each of them subjective in their own way, have helped).

Though there were earlier attempts, it was only really towards the end of the 20th century that algorithms enabled population figures (such as UK census data) to be visualised spatially in digital maps. For some examples, see the cartograms from Danny Dorling’s ‘New Social Atlas of Britain (1995) and also ‘Worldmapper’ Tina Gotthardt and Benjamin Hennig’s terrific up-to-date world cartograms where the size of a state is visualised in human terms, such as the relative size of its population or, as here, its proportion of confirmed Coronavirus cases over a particular period.

Maps need to be clear and understandable. But of course there’s also a lot to be said for complexity. People like scientific data, and this year has been big year for science and its associated debates. Historically, there are no shortage of maps whose creators have clearly delighted in cramming as much scientific content into them as possible, even to the point of confusion. We might call this the rhetorical use of science in maps, the deployment of science an alluring device to emphasise the accuracy, seriousness or reliability of what is being shown, or even as a self-promoting device used by a mapmaker to demonstrate his or her scientific acumen.

King's Topographical Collection: curator's pick

In October we released 18,000 digital images of early maps and views from the Topographical Collection of George III. View the collection on Flickr Commons, and access images via the maps and views' catalogue records on Explore. Here's my choice of five compelling maps from the collection. 

1. Plan of Manila, 1739.

Maps_k_top_116_40
D. Antonio de Roxas, Manila, c. 1739

This is the only recorded example of this 1739 edition of the 1717 town plan of Manila in the Philippines. Manila was, and is, a key international centre of trade, and the map was actually produced in the town (in a tiny vignette we can see a copy being presented by the Spanish governor of the Philippines to King Philip V of Spain). There’s probably no better image of a bustling commercial site, proof that a town is not just about its architecture and layout, but its people and processes too. This map has additional resonance, because Manila was besieged and looted by the British in 1762, and annotations in the map’s bottom right refer to aspects of the battle. Could it be George himself annotating the map according to reports he had received of the battle?

2. Map and survey of Plymouth Harbour, 1780

Maps_k_top_11_79
Matthew Dixon, Plan of Plymouth, 1780.

This is the map that reminds me most of the strong links between mathematics and art in maps. It’s a large and serious military drawing, officially commissioned and with an accompanying report, of a key strategic naval installation and site of British maritime strength and power. It was drawn up as part of the earliest mapping activities for what would become the Ordnance Survey a few years later, enacted in response to the threat of invasion from Napoleonic France. So why is it so stunningly and mesmerizingly beautiful? It’s a question that should infuriate everyone who sees maps purely as cold communicators of facts and 'data.'

Is it a map or is it a view? What is that ominous large shadow looming in, Holbein-like, from stage left? Who cares! This is an intriguing and brilliantly composed aquatint print showing a collection of views of picturesque Kingston-upon-Thames. From above, in profile, from a distance away, it’s a multi-faceted image that invites us to dissolve our perception of the differences between vistas and to see them as a combined and rounded description of a place. Cartographic cubism! As Horner himself wrote, ‘…the whole, blended into one design by a picturesque fore-ground, forms a faithful view of the parish.’ It’s a joyous visual experience, with a few intrigues and little jokes (note the bungling surveyor- stonemasons in the foreground) thrown in for good measure.

4. India, 1619

Maps_k_top_115_22
William Baffin, Map of the Mughal Empire, 1619.

This is a portentous map - the earliest British printed map of part of India. It marks the beginning of British cartographic involvement in India that would reach new levels of science-led imperial control through mapping by 1900. The Roe-Baffin map was produced following the earliest English trade mission to the Mughal empire. It has a stellar cast: Sir Thomas Roe, the diplomat who headed up the embassy. William Baffin, the navigator who went on to attempt to locate the North West Passage (Baffin Island is named after him). Reynold Elstrack, one of the earliest native English engravers.

The map was one of very few English-produced maps to provide a model for later Dutch atlas maps by Blaeu, Janssonius and others. English mapmakers were more often the copycats. The engraving of a Mughal seal has been expertly assessed by the British Library’s Dr Annabel Gallop.

5. The United States of America, 1782

Maps_k_top_118_49_b
John Mitchell, Map of the British Colonies in North America..., 1775 (updated to 1782).

This is a map with a story and a reminder of the power – and paranoia – that can be associated with maps. John Mitchell’s map of ‘the dominions of North America’ is a tremendous cartographic achievement in its level of description of this vast area. Yes, standing on the shoulders of earlier maps, but adding a vast quantity of descriptive notes and even including naming Native American nations (who were nevertheless ignored in what followed).

On another level, this late edition of the map is a piece of history, being the copy used by the British delegation at the 1782 Treaty of Paris where the terms of the peace following Britain’s defeat at the hands of the United States were established. The map has been marked up in red to show the lines of the new border the British would be happy with. But at the conference they realised that they didn’t have to cede quite as much as they had drawn. The map suggests that Upper Canada (much of modern-day Ontario) was also available to the USA. So later the British government ordered the British Museum to lock the map away so that nobody, particularly no inquisitive Americans, might see it and demand any more.

It was hidden from view until the early 20th century.

The King’s Topographical Collection wonders

You may already be aware with all the recent publicity surrounding the release of the first batch of images from the King’s Topographical Collection that this is indeed an incredible resource with countless unique maps and views. I thought I would share with you some of my favourite items which I think are wonderful examples you may encounter while browsing the collection. Fascinating not only because of the unusual format of some of the items or unexpected subject matter but also the fact that they provide a glimpse of what was interesting and worth collecting back in the 18th and 19th centuries. With 18,000 images available on Flickr there is plenty to discover!

 

Maps_k_top_63_40_level_2

Maps K.Top.63.40. Tour de Cordouan, a l'Entrée de la Garonne. About 1680. 

This 17th century intricate architectural drawing shows the structure of the Cordouan lighthouse (Phare de Cordouan). What is unusual about this drawing is the use of flaps which are pasted over a round base representing the building. These flaps can be lifted to reveal a detailed layout of the various levels of the lighthouse.

Phare de Cordouan is situated at sea near the mouth of the Gironde Estuary 4.3 miles off the French coast and was constructed in 1611 to Louis de Foix, the royal engineer’s design. The original structure comprised of five storeys and included the grand entrance hall, King’s chambers, a chapel, apartments for the keepers and, of course, the lantern itself. The entire building was richly ornamented with particular attention paid to grand décor and its unique design became a symbol of power. Phare de Cordouan is one of the oldest lighthouses in France and is still in use today.

 

Maps_k_top_36_24_2_b

Maps K.Top.36.24.2.b. Plan of the most remarkable effects of the earthquake, which happened ye 27th of May, 1773; at the Birches, in the Parish of Buildwas and near Coalbrookdale in the County of Salop… 1773.

This unusual map represents an aftermath of a geological event which occurred in 1773 near the village of Buildwas in Shropshire. The eye-catching title resembles a sensationalist headline style although soon after the event it was established that the cause was a landslip rather than an earthquake - in the mapmaker’s defence the term earthquake was used occasionally to describe a landslip in the late 18th century. Whatever the cause, the map is a contemporary record of an event that significantly changed the local landscape and impacted the community.

It delineates the extent of the damage including the pre- and post- earthquake configuration of the area such as the road location, the old and the new course of the River Severn, as well as the chasms and areas where the ground was raised. The force of water damaged the existing bridge which was eventually replaced in 1796 by a cast iron bridge built to the design of the Scottish civil engineer Thomas Telford (it was actually his first iron bridge). The map was published just four months after the event in the context of an inquiry into the reconstruction of the turnpike road and the river channel.

Maps K.Top.27.41.7. Fox's new floating bath, now lying opposite Surry Stairs, near Somerset Place, on the Middlesex Side of the Thames, for the Reception & Use of Bathers. About 1810. 

This rare ephemera from the beginning of the 19th century advertises an innovative and rather bizarre concept: a boat specifically constructed to serve as public baths. Conveniently moored on the River Thames in central London this floating facility would be ‘the compleatest and best adapted of its kind for bathing in England’.

The adventurous entrepreneur worked out all the logistics explained in the accompanying text. The floating baths would be made available on a subscription or a single-entry basis and serviced by watermen transporting the bathers to and from the boat. There was a promise of a pleasant experience in the stylish décor and even health benefits claiming that the facility was recommended by doctors. These were rather doubtful claims as bathing in the Thames surely could not be beneficial considering how polluted the River was in the 19th century. There is no record that such a boat was ever constructed but the idea was realised on a much larger scale later in the century when in the 1870s floating baths opened on the Westminster embankment with water filtering systems in place.

Maps K.Top.119.17. [A coloured chart of the upper part of Lake Erie at Fort Erie and a detailed plan of Fort Erie, together with three cross sectional drawings]. 1764. 

This manuscript plan of Fort Erie (Ontario, Canada) is a prime example of fine draughtsmanship. It has an artistic element to it with lot of attention paid to aesthetics. The plan incorporates the fortification elements drawn to different scales to fit the sheet without making it look overcrowded. Produced by Franz Pfister an engineer and an accomplished surveyor with a military purpose in mind, it provides an insight into 18th century fortification design techniques and shows in detail individual structures including cross sections and views of buildings.

Fort Erie was constructed on the north-western shore of Lake Erie in 1764 after the Seven Years’ War when Great Britain gained the territories in New France. It was the first British fort built in order to establish a communication network between the Niagara River and the Upper Great Lakes and played a significant role as a supply depot for the British troops during the American Revolution.

Maps K.Top.117.24.1.a. Sketch of the Northern Part of Africa Exhibiting the Geographical Information Collected by the African Association. Compiled by J. Rennell. 1790. & 1792.

This printed map is a great example that demonstrates the process by which maps were brought up to date. It was prepared for the Association for Promoting the Discovery of the Interior of Africa and contains manuscript annotations displaying the new geographical detail acquired by Major Daniel Houghton during his expedition of 1790-1791. The updates include amendments to spelling of place names, corrections of positioning of settlements, the courses of rivers, as well as extent of lakes and mountain ranges.
The map along with the accompanying handwritten Memoir and a letter from Henry Beaufoy a secretary of the Association, to Sir Frederic Barnard, George III’s librarian, constitute a primary resource on Houghton’s expedition. The documents reveal that the expedition was not strictly a geographical enquiry. Major Houghton also investigated the feasibility of establishing a trade route, commercial prospects and potential demand for commodities which could be supplied by the British including military equipment and supply of ammunition.
