The removal of military installations from OS maps was at its height in the 19th century and the World Wars, but throughout the Cold War and beyond, many sensitive sites were left off the maps entirely. It took the public availability of high-resolution satellite imagery at the turn of the 21st century to render this type of censorship largely ineffective, although labels are still omitted in some cases.
The Ordnance Survey did survey and map sensitive sites, but those maps were military-only. The differences between these military maps and the public maps make for a number of interesting comparisons: see the post for examples.
Throughout history, maps have been made and used in different ways and for different purposes. They can be seen as cultural artefacts, artworks, sacred objects and tools for wayfinding. Often their purposes are legal—they can be used to administer property regimes, resolve proprietary disputes or make territorial claims. But what about the laws that regulate the maps themselves, that decide who can own them or who can distribute them? This website explores these questions, juxtaposing images of maps with the legal documents intimately involved in their creation and circulation.
The project focuses on mapmakers in London, Edinburgh, Melbourne and Sydney, and seems to be in the early stages, with only a dozen cases, relating to infringement and other copyright disputes, listed.
Opening today at Hughenden Manor: a permanent exhibition on the secret wartime mapping activities that took place at the Buckinghamshire mansion during the Second World War.
In rooms never before opened to the public, the installation features original photographs, records and memories of personnel involved at the time.
In newly accessible spaces used by the mapmakers themselves, the interactive exhibits shed light on how Hillside played such a significant role in shaping the outcome of the war. […]
Codenamed ‘Hillside’, Hughenden played such a critical role supporting the pilots of nearby Bomber Command that it was on Hitler’s list of top targets.
Around 100 personnel were based here, drawing up the maps used for bombing missions during the war, including the ‘Dambusters’ raid and for targeting Hitler’s mountain retreat Eagle’s Nest. Skilled cartographers produced leading-edge maps from aerial photographs delivered by the RAF’s reconnaissance missions.
The BBC News story provides more detail: some 3,500 hand-drawn target maps were produced at Hughenden Manor during the War.
A project of Cambridge’s Violence Research Centre, the London Medieval Murder Map is an interactive map that plots 142 murders from the first half of the 14th century onto one of two maps of London: a 1572 map from Braun and Hogenberg’s Civitates Orbis Terrarum or a map of London circa 1270 published by the Historic Towns Trust in 1989. The interactive map is powered by Google Maps, but the Braun and Hogenberg is not georectified, so the pushpins shift as you toggle between the base maps. [Ars Technica]
Londonist’s Fake Britain map: “We’ve put together a map of fictional locations from film, TV, literature and other sources. Take a look around this alternative nation and see how many places you recognise. From Judge Dredd to Vanity Fair, it’s all here.
“The vast majority of entries are well defined geographically. Some—such as Beanotown and Blackadder’s Dunny on the Wold—are a little more nebulous, but we’ve added them for fun. Hogwarts is an unmappable location (unless it’s a Marauder’s Map you’re looking at), but we’ve had a go anyway.”
They’re looking for additions and corrections to the map: this is a work in progress. [Scarfolk]
During World War I, Australian troops staying at nearby Hurdcott Camp carved a gigantic map of Australia into a Wiltshire hillside. Chalk gravel was used to fill shallow trenches to create an outline map some 150 feet wide with 18-foot-tall letters. Since then, despite a restoration in the 1950s and its designation as a Scheduled Ancient Monument, the map has faded, but for the past four years the Map of Australia Trust has been working on restoring the map. It was finished in time for Armistice Day. More from BBC News (video) and Historic England. [Jonathan Potter]
Maps of bus, tram and trolley networks are, I think, more likely to use geographical maps of the city’s road network as their base layer than subway and rail maps. That’s not always the case—nor has it always been the case. Take this 1947 map of London’s trolleybus and tram routes, executed by Fred J. H. Elston. Cameron Booth finds that it has “more in common with modern best practices for transit diagrams than with something that’s now 70 years old.” On the other hand, Ollie O’Brien, writing at Mapping London, thinks that this map proves that “the simplicity of the tube map doesn’t translate very well to London’s complex road network. So perhaps this is why the idea almost didn’t survive for above-ground networks, and London’s more modern bus maps (now discontinued) have always used the actual geographical network.” Christopher Wyatt, sharing the map on Twitter, notes a big, Westminster-shaped hole in the trolley network that matches London’s speed limit map: “It does seem as though there is a historical pattern of aversion to transportation equity from Westminster.”
The first map produced by the Ordnance Survey, their blog reminds us, was this map of Kent. Published in 1801 at the scale of two inches to one mile (1:31,680), it took three years to complete; the OS started in Kent over fears of a French invasion. As such, the map “focused on communication routes and included hill shading to ensure men at arms could interpret the landscape with precision. Over time, this map design became less focused on these elements and was developed to appeal to a much wider audience.”
Forgotten Wrecks of the First World War is an interactive map of more than 1,000 wartime wrecks along England’s south coast. Like much of the material and personal history of that war, the wreck sites—”which include merchant and naval ships, passenger, troop and hospital ships, ports, wharfs, buildings and foreshore hulks”—are degrading; this is a project designed both to raise awareness and preserve information. Selecting a wreck site brings up a wealth of detail about the ship, its current state, and the circumstances of its loss. More at the project page and from BBC News. The map itself is a basic Mapbox affair, with a layer that only looks vintage (there are motorways). [Kenneth Field]
Manchester: Mapping the City (Birlinn, 4 October), the latest in Birlinn’s line of cartographic histories, is the result of years of research and collecting by authors Terry Wyke, Brian Robson and Martin Dodge. “This book uses historic maps and unpublished and original plans to chart the dramatic growth and transformation of Manchester as it grew rich on its cotton trade from the late 18th century, experienced periods of boom and bust through the Victorian period, and began its post-industrial transformation in the 20th century.” The book’s home page has sample chapters and links to Mancunian maps online.
