I’m delighted that 1,277 maps from our War Office Archive have been added to the Georeferencer in the last few days. These military intelligence maps relate to Eastern Africa, particularly modern-day Ethiopia, Kenya, Malawi, Mozambique, Somaliland, Tanzania, Uganda, Zimbabwe and parts of South Africa. The British Library has catalogued, conserved and digitised the archive with generous funding from the Indigo Trust. You can find out more about the maps here https://www.bl.uk/collection-guides/war-office-archive.

The maps are already accessible on the web through several different channels. A Google Map index shows the central point of each map sheet and provides links to catalogue records and high-resolution digital images, viewable on Digitised Manuscripts or available for download from Wikimedia Commons. You can also download text that has been extracted from the images using computer vision. However, we hope that the rich geospatial data provided by volunteers on the Georeferencer platform will open up these maps to new forms of research and discovery.
In terms of the Georeferencer project as a whole we now have 63902 maps georeferenced on the platform which is an amazing achievement. An exciting new project, ‘Machines Reading Maps’ [https://www.turing.ac.uk/research/research-projects/machines-reading-maps] based at the Alan Turing Institute is also now using our georeferenced Goad fire insurance maps. Thanks to all those who contributed to their georeferencing, they have been used by several research projects and are an invaluable resource.

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!
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. 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.

Today we release 18,000 digital images of historic maps, views and texts from the Topographical Collection of King George III into the public domain.
The collection has been digitised as part of a seven-year project to catalogue, conserve and digitise the collection which was presented to the Nation in 1823 by King George IV. This is the first of two planned image releases.
For the first time, anybody who wishes to can remotely view, search, research and enjoy one of the world’s richest and most varied public collections of the history of place.
The idea of remote or virtual travelling is a particularly common one today thanks to the seamless interfaces of online map viewer that simulate the idea of airborne travel and evoke the excitement of discovery. However, the idea of virtual travel has a long history, and is well illustrated by the travel-averse king who resided in his palaces and viewed the world through his collection of maps and views. This is the Google Earth of the late 18th century and the journeys it can take you on are no less informative, intriguing, and instructive of the many facets of past eras.
What is K.Top?
The King’s Topographical Collection (K.Top) is one part of the Geographical Collection of King George III (the other parts are the Maritime and Military collections). The nucleus of the collection was assembled from 1660, but added to considerably after 1760 by the king’s librarians and agents. The collection was presented to the British Museum (from 1973 British Library) as a distinct part of the King's Library in 1823,. For more on the history of the collection see this post by Felicity Myrone.
What is in it?
It’s probably easier to list what isn’t in this collection. It totals around 40,000 printed and manuscript maps, views, charts, texts, architectural plans, prints, atlases and ephemera. The collection is arranged geographically, with around 40% dedicated to the British Isles, one third covering the Europe of the Grand Tour, and 10% for British areas of influence such as North America, the West Indies and India.
What themes does it include?
Too many to mention, but here’s a sample: landscape, tourism, antiquarianism, architecture, rural life, fine art, agriculture, medieval and church studies, urban planning and development, industrialisation – canals and transport, military history, the history of collecting, the history of cartography, the Grand Tour, royal palaces and stately homes, science and invention, the history of exploration, American Independence.
As a product of the 16th-19th centuries, the collection is also associated with imperialism, and the role of maps in facilitating imperialist activities both practically and ideologically. We hope that the release of this material will facilitate research and greater understanding of these aspects of the past.
How can I access it?
18,000 images are available via the file-sharing site Flickr, which you can find here https://www.flickr.com/photos/britishlibrary/albums/72157716220271206
Images from the collection are also tagged George III Topographical Collection https://www.flickr.com/photos/tags/georgeiiitopographicalcollection

This final chapter discusses a number of cartographic innovations from the middle of the twentieth century onwards that exploited the ability of photographs to capture data - from developments in aerial photogrammetry, through multispectral satellite mapping and surveillance imagery, to the digital map platforms of today.
Technical innovations that had begun during the Second World War soon extended into the civilian sphere with the widespread adoption of aerial photogrammetry by national mapping agencies worldwide – a development that arguably had a greater impact than any other on mapping practices of the twentieth century. New radar surveying techniques allowed air photographs to be pinpointed on the ground more accurately, more economically and over far greater areas than before, bringing vast regions of inaccessible terrain within the mapmaker’s scope for the first time.
Between the 1950s and the 1980s, the whole of the Soviet Union was mapped in this way, resulting in over 300,000 sheets at a scale of 1:25,000. During the same period, the British Directorate of Overseas Surveys also covered over 2.5 million square miles of land, mostly over former British colonies and administrations that had no mapping capability of their own. The image below shows an isolated settlement and nearby areas of subsistence agriculture in eastern Nigeria. Maps made from such images contributed to state economic and social planning initiatives.

Mapping vast, sometimes featureless, inland regions led to some eccentric examples of cartography. The following detail is taken from one Australian map sheet that covers more than 2,750 square kilometers of the Great Sandy Desert. Each square is one kilometre on the side. Of the total 3,062 sheets in the series covering the whole country, only half were printed – this sheet was selected for print on account of a single track that meanders briefly along the bottom edge, before diverting back to the adjacent sheet beneath.
Detail of Australia 1:100,000 topographic survey, Weenoo Sheet 3256, 1972. BL Maps 90050.(125.).
Widespread use of air photographs also led to security concerns. As part of the British reconstruction effort after the war, the RAF covered the whole of Great Britain with aerial photography in order to assess bomb damage. Between 1945 and 1951 the Ordnance Survey published the photography as OS Mosaics, large-scale rectified photomaps of towns, cities and some rural areas.
After many images had already been published, it was feared that foreign states might benefit from the level of detail of sensitive sites that was revealed. Further editions of the same sites were therefore over-painted before publication in order to remove or disguise these features. The military airfield shown in the image below has been replaced by a fictitious pattern of fields and country lanes in the later version beneath. In 1954 OS Mosaics were removed from sale entirely.

An alternative and innovative approach to photomapping was taken in Sweden. From as early as 1935, aerial photography was incorporated into the Ekonomisk Karta land use series. The large-scale photographs provided a base layer onto which topographic, cadastral and land use symbols and colours were added.

Stereo pairs of air photographs could be made into three-dimensional ‘anaglyph’ images, which were viewed through coloured glasses. Examples of these were created for military planning purposes during the Second World War, such as a German series from 1944 showing the Istrian coastline (held at BL Maps Y.3842.). After the war, the French national mapping agency published a number of anaglyphs in a Relief Form Atlas of 1956. The purpose of the atlas was to teach readers to understand the mapping of a wide variety of landscapes by showing three-dimensional views alongside maps of the same location. The following image of the volcanic cone atop Mount Karthala in the Comoros is striking when viewed through a pair of red and blue 3D glasses.

Images taken from aeroplanes were soon joined by those taken from satellites, after the launch of Sputnik by the Soviet Union in 1957 sparked the Space Race between themselves and the USA. The speed of technological developments over this period is encapsulated in the three images following. This annotated photograph taken from a military aeroplane in 1936 captures the curvature of the Earth for the first time, and shows the highest point then reached by man.

Only two decades later an unmanned Russian spacecraft, Luna 3, took the first pictures of the far side of the moon as it orbited in 1959. The images were transmitted back to Earth by radio link and published in Moscow the following year in the Atlas of the Far Side of the Moon.

Within the next ten years man too had travelled round the moon. American astronaut William Anders took this iconic photograph, which looks back at the Earth as it rises above the lunar surface – an image of the world that had previously been possible only in the imagination.

Both the Soviet Union and the USA launched military reconnaissance satellites during the early 1960s that were capable of creating high resolution imagery for intelligence and mapping purposes. Civilian satellites followed, perhaps the most successful of which was Landsat, launched by the USA in 1972.
Multispectral satellite imagery became an essential feature of land survey and resource management, leading to a proliferation of thematic maps, and a new category of mapping under the title satellite image maps. The ease with which satellite imagery could track changes over time in the environment also brought new insights to many areas of study, including urbanisation, de-forestation, analysis of weather systems, and ocean dynamics.

Nowadays aerial photographs and satellite images are ubiquitous in digital mapping products that have become a common feature of everyday life. 2001 saw the launch of Google Earth, an application in which satellite imagery and aerial photography are draped over digital terrain models to provide interactive three-dimensional map views.
Screenshot showing the Island of Stromboli, Google Earth, 2020.
In other applications, maps and photographs are now interchangeable - users can choose between map or satellite viewing modes.
Screenshots taken from Google Maps, 2020.
Google Street View, launched in 2007, integrates terrestrial photography and cartography to create a model of the world from a horizontal viewpoint – a mode of representation with antecedents in artworks of former times. In the early 1900s, Eugène Atget started to make images of the older parts of Paris with the intention to record streets and buildings that risked being torn down and re-developed. By 1920 he was able to write, ‘This enormous artistic and documentary collection is now complete. I may say that I have in my possession all of Old Paris’.

Half a century later, American artist Ed Ruscha created an artwork entitled Every Building on the Sunset Strip by fixing a camera onto the back of his truck and driving up and down as it took pictures on a timer. His intention was to recreate the experience of moving through the landscape.

Google Street View now also employs cameras fixed to cars, or strapped to pedestrians’ backs, to create strips of 360-degree images stitched together. The artistry and focus on aesthetic have been lost in these pictures made by machines, but those qualities have been replaced by functionality. Google’s georeferenced, navigable imagery allows users to search and interact with a vast database of (mainly business) information. The corner building shown below, tagged so that one can choose to see the menu or make a booking at the restaurant within, is the same as that in the Atget photograph from 100 years before.
Screenshot taken from Google Street View, 2020.
The perceived realism of digital maps and photographs makes them particularly persuasive. However, two posts reproduced from Twitter, below, document conflicting facts about the shooting down of an American drone by Iranian forces in June 2019. The first, published by US Central Command, shows the drone flying through international, not Iranian, airspace when it was hit, while the second image, posted the following day by the Foreign Minister of Iran, shows the drone in a different location, within Iranian airspace.
Screenshot of Image posted by US Central Command on Twitter, 2019.
This incident reminds us that the latest generation of maps and images remains as susceptible as any before to manipulation or exploitation.
Today more than ever, maps and photographs go hand-in-hand in our ceaseless attempts to capture, model, and mould the world around us.

We have come to the fourth and final qualifying group of our British Library world map world cup, and in it we have four extraordinary and breathtaking examples of cartography from between the 11th and 20th centuries. I hope the following descriptions, links and images will provide you with what you need to make your difficult choice.
Vote for your favourite over on Twitter (@BLMaps). The top two maps will go through to the quarter finals tomorrow, Friday July 10th.
1.Beatus of Liébana world map. Drawn in Burgos, Spain, between 1091 and 1109 (Add.MS 11695)
The 15 surviving 'Beatus' maps are included in textual commentaries on the Apocalypse of St John (from the New Testament Book of Revelation) written by the Spanish theologian Beatus of Liébana (fl.776–86). The British Library’s example, arguably more powerful and brooding than the others, is a diagrammatic image with powerful pictorial elements. These include fishes swimming in the sea encircling the world, the‘molehill’ mountains and the unforgettable image of the Garden of Eden at the top of the map, in the east. It was produced in northern Spain (in the monastery of San Domingo de Silos) in around 1109, and as a result reflects Islamic pictorial influences that had spread from northern Africa.

2. The Contarini-Rosselli world map. Engraving, published in Florence in 1506 (Maps C.2.cc.4).
This is the earliest surviving printed map to show any part of the Americas. It was published in Florence in 1506, only a decade or so after Christopher Columbus's first voyage in 1492. The map, which is by the Venetian Giovanni Matteo Contarini and Florentine Francesco Rosselli, has been celebrated for its American content ever since this only known copy was purchased by the British Museum in 1922. But it is an extremely early and partial glimpse of eastern America: Newfoundland and Labrador are shown cemented on to Kamchatka, Cuba and Hispaniola are floating next to Japan, and South America is joined to the vast Southern Continent.

3. Aḍhāīdvīpa. Painted in Rajasthan in 1830 (Add.Or. 1814).
This is a map showing the structure of the world of Jainism, a religious system founded in northern India in the sixth or seventh century BCE. The map, which is in Sanskrit, was painted onto cloth in Rajasthan in 1830, and like many of the European medieval mappamundi, it illustrates a fusion of human and sacred geography. At the centre is the recognisable, terrestrial world of people (Mount Meru is at the centre, as it is in the Korean Ch’ ōnhado maps). Surrounding it is the spiritual world: green concentric-ringed continents illustrated by lunar symbols and separated by fish-filled oceans, beyond which is the outer land of the jinas or prophets.

4. Self determination world map, by F. Klimesch. Published in Berlin in around 1919 (Maps CC.5.b.29).
The only 20th century world map to make it into our World Map World Cup competition (not that there aren't many great 20th century world maps, just a mere 16 places to fill), is a German map produced in the wake of the peace treaties following the defeat of Germany and the end of the Great War, 1914-1918. It shows the victorious allies Britain, France, Russia and the USA as soldier figures, holding leashes attached to their respective national beasts. These beasts have been placed over the colonies they controlled.
The title explains why: 'What would be left of the entente if it made serious the right of self-determination of their own people and let go of the reins!' The map calls out the Allies' decision to confiscate German colonies under the principle of 'self determination,' but to retain theirs regardless. Given the century-long process of decolonisation that ensued, and ensues, the map is profoundly and powerfully prescient.

Welcome to Group three of the British Library's world map world cup competition, where you get to select our favourite historic world map for us.
This group contains some astonishing artefacts from the last one thousand years, and I'm happy to provide further information on them to help you make up your mind.
When you have done so, vote for your favourite over on Twitter (@BLMaps). The two maps with the most votes will go through to the quarter finals on Friday.
1. The Anglo-Saxon World Map. Drawn in Canterbury between 1025 and 1050 (Cotton MS Tiberius B.V.).
For a world map containing such a quantity of information, the Anglo-Saxon world map is extraordinarily early. Much of this information relates to the Roman world: key walled towns such as Alexandria, Rome, Constantinople, the Pillars of Hercules at the bottom edge marking the limit of the world as known to Europeans, and lines marking the division of Roman provinces. Its genesis is possibly the first century map ordered by Julius Caesar. At any rate, the people who made the map would have felt themselves still to be living in the great Roman era.

2. The Martellus world map. Drawn by Henricus Martellus Germanus in Florence, around 1490 (Add. MS 15760).
Henricus Martellus, or to give him his proper name Heinrich Hammer's world map is very similar to the 2nd century geographical picture presented by Claudius Ptolemy (see group one). But there are some updates. For example, Scandinavia appears, as do features taken from an account of the journey of Marco Polo. But the most momentous update is the one that shows the Indian Ocean not as an inland sea, but open, with the southern tip of South Africa navigable. Martellus knew this, because Bartholomeu Dias had sailed around it in 1488. The effect was to contest the hallowed ancient perception of the world, literally cutting part of the map's border away in the process.

3. Chinese globe, by Manuel Dias and Niccolo Longobardo. Made in Beijing in 1623 (Maps G.35.)
This earliest surviving Chinese globe was constructed in Beijing by Italian Jesuits, most probably for a scholarly audience, in order to demonstrate geodetic principles such as longitude, latitude, meridians and parallels. Much of the globe, including large passages of text, derives from the giant world map by Matteo Ricci of 1602. But if you want to show things relating to the spherical nature of the earth, you really need a sphere in order to do it properly, hence the globe.
Geodesy had been known in China well before Europe, and we know that globes were also constructed before his one (though they have not survived), but such things were not part of Chinese culture at this time. The 'gift' of scientific enlightenment was used as a Trojan horse by the Jesuits to impose their religion upon China.

4. World map by Antonio Sanches, drawn in Lisbon in 1623 (Add. MS 22874)
This is an extraordinarily beautiful, large world map, emphasising coasts and navigational features. Delicate and elegant, blues and golds, painted and coloured with consummate skill. This indicates that it was not intended to go on board a ship. It presents the Portuguese view of the word, celebrating Portuguese influence well beyond Iberia with the Quinas (Portuguese arms) stamped upon areas as far afield as South America and China. The map also contains a significant (to say the least) quantity of religious imagery, the spread of Catholicism being a pillar of this world view, and violently enforced. Ironically, given the confidence this map oozes, by 1623 Portuguese dominance in world affairs was being increasingly contested by that European upstart, the Dutch.

World maps are amazing things for their ability to conceptualise the earth and capture it in miniature. Of course, this comes at a price. World maps, perhaps more than any other 'image,' are powerful and subjective. Each one contains a particular world view, and throughout history they, or rather their makers, have tended use them to impose their views upon others. Who is at the world's centre? Who is relegated to the margins? Who is shrunken in size, and who is removed from the map all together?
So it's a strange quirk of history that during the 20th century, that most antagonistic of eras, the world map came to be seen as a symbol of co-operation, togetherness, shared heritage and environmental awareness (thanks in no small part to NASA's famous 1968 Earthrise photograph of our vulnerable planet hanging in the void). As a result, a world map is now capable of saying “we’re all in it together”. It’s World Population Day on Saturday 11 July, so let's attempt to reclaim some of that spirit.
I'd like to invite you to help us choose the British Library’s favourite world map. Over the next week I’m going to introduce sixteen of the most extraordinary and groundbreaking world maps from between the 11th and 20th centuries, carefully selected from the British Library’s collection of over 4 million maps.
The maps will be arranged into 4 groups, with one Twitter poll per day (Monday to Thursday) deciding which two maps from each group will go through to the quarter finals on Friday. The semi finals and final poll will happen on Saturday, and we’ll think up something special for the winner. Follow us @BLMaps, hashtag #BLWorldMapWorldCup.
What selection criteria might you use? Well, did the map capture some signal shift in civilisation? Is it unique, beautiful, technically accomplished or cleverly made? Or do you just like it because you like it? That’s valid too.
Hopefully through this just-for-fun competition it will be possible to appreciate the history of a world of multiple viewpoints; and, though it won't be easy, to begin to rediscover ones which have been erased.

The previous part of this article discussed the introduction of photography into maps and mapmaking over the first hundred years after its invention in the 1830s. Photography was initially used to complement information found on the map, by recording topographical views or objects of antiquity, and it was incorporated into the map production process from the 1850s. In this early period photographers also began to capture the work of survey teams in the field. Soldiers in the British Royal Engineers were specially trained in the use of cameras for this purpose. This group photo from circa 1860 was taken by one such soldier-photographer, and shows colleagues posing in a cutting cleared through the forest to enable survey work along the border between the United States and Canada.

Cameras were also employed to record advances in cartographic technology and instrumentation. The following scenes were set up to demonstrate use of the latest levelling instruments by staff at the Survey of India in 1909. Beyond this original purpose, the first image also illustrates the colonial hierarchy in the division of labour that was based on race.

Another later image demonstrates the same division of labour in Africa amongst members of the Anglo-Belgian Congo-Zambesi Boundary Commission, as European surveyors take observations from a trig point around 1930. A contemporary account of the survey published in The Geographical Journal highlights the pressure the Commission was under from the two European administrations to agree and demarcate this African boundary quickly, so that valuable mining rights could be settled between them.

After the First World War there was a drive to realise the potential of aerial photography in new fields of geographical and archaeological analysis away from the battlefield. In 1919 G.A. Beazley published an article entitled Air Photography in Archaeology, in which he described wartime aerial survey work carried out around Samarra in modern-day Iraq. The survey had revealed the layout of an ancient city, details of which were transferred to the military map, below, though they were evident only from the air.

Another pioneer of aerial archaeology was O.G.S. Crawford, who was appointed the first archaeological officer at the Ordnance Survey in 1920. He used air photographs made by the RAF to measure the length of the Avenue at Stonehenge, and later joined with Alexander Keiller to make an aerial survey of archaeological sites in several British counties. Together they published Wessex from the Air in 1928.

With the introduction of black and white infra-red photographic film in 1931, a new kind of geographical analysis became possible. Infra-red film responds to different wavelengths of light from the panchromatic type, and was useful in indicating high tide lines and different types of vegetation. The glass slide below shows an infra-red image from the 1930s, in which bare hills appear dark and sharply distinguished from the characteristically bright areas of cultivation at their feet. The water in the meandering river also shows up black.

With the outbreak of the Second World War the use of infra-red film was amongst a number of techniques trialled with aerial photography to map the gradients of enemy-held beaches. In the end, the most successful method used air photographs taken with panchromatic film to determine the shape of the seabed by studying the shapes and velocities of wave patterns as they came to shore.

This crucial element of wartime invasion planning appears in the following beach map of an island off the coast of modern-day Myanmar. The diagrams in red, on the right, were derived from air photographs and show the beach gradients at different numbered points on the map.

Photography fulfilled other roles in wartime invasion planning. During the Second World War German forces created volumes of geographical intelligence by country, in preparation for the invasion of foreign nations in Europe, North Africa and the Middle East. These volumes included photographs that complemented the information found on maps by giving a visual impression of the lie of the land, and by providing additional geographical intelligence. Pictures illustrating local geomorphology appear alongside images of industrial buildings, harbours and fortifications.
In the volume dedicated to the South Coast of England a number of what appear to be pre-war tourist postcards have been reproduced. The example below shows location 255 on the map of the Isle of White that follows. The accompanying text explains its inclusion - ‘Narrow sandy beach in front of the bank fortification, is exposed at low tide.’

Advances in aerial photogrammetry had continued between the wars with the invention of multiplex instruments in Italy and Germany in 1930, which allowed a single operator to map large areas quickly from small scale air photographs. In the United States the technique was adopted by USGS, the national mapping agency, and was widely used to map agricultural areas under New Deal public works projects, so that by the start of the Second World War a large number of trained photogrammetrists was available for the American war effort.
Many of these photogrammetrists were put to work creating photomaps of islands in the South-East Asian Theatre, producing innovative sheets that consisted of a conventional line map on one side and a rectified photomap on the reverse.

Similar advances had been made in large-scale aerial photogrammetry with the invention of the slotted template method in the United States in 1936. This was a development of radial line plotting techniques first promoted by the British Air Survey Committee in the 1920s, and provided a method of adjusting and correlating large numbers of overlapping air photographs.
One of the most intensive periods of large-scale aerial survey activity during the war came with the secret preparation of the so-called ‘Benson’ series of maps, named after the RAF station in Oxfordshire from which many of the survey and reconnaissance flights departed during 1942–43. The series was completed in advance of the D-Day landings in 1944, and features an overprint showing German defences along the Normandy coast of France. The British Library is currently conserving a representative set of materials used in the compilation of these secret maps, which will be made available at shelfmark BL Maps Y.4169. The material includes a US Army report that compares the accuracy of a sheet made by the multiplex method with one made by the slotted template technique.
