A map of the battlefield of Antietam held by the New York Public Library that shows the location of graves of soldiers killed in the 1862 U.S. Civil War battle is the subject of a piece in today’s Washington Post.

Civil War historians are hailing it as an important new way to visualize the toll of the huge battle outside Sharpsburg, Md., in 1862.

“Every one of us who’s looked at this absolutely flips out,” said Garry Adelman, chief historian for the Washington-based American Battlefield Trust, which works to preserve historic battlefields. “This will reverberate for decades.”

The map is the only one of its kind known to exist. It was digitized by the New York Public Library, which owns it, and was spotted online by local historians a few weeks ago.

The map doesn’t just mark graveyards, it notes the burial locations of specific regiments and brigades—and in 45 cases, individual soldiers.

Bending Lines, an Online Exhibition from the Leventhal Center

Published on by Jonathan Crowe

Bending Lines: Maps and Data From Distortion to Deception, the latest exhibition from the Leventhal Map and Education Center at the Boston Public Library, is a wide-ranging, comprehensive look at the relationship between maps and the truth. We expect maps not to lie, but maps have misled, propagandized or at the very least provided a particular perspective for as long as there have been maps.

Every map is a representation of reality, and every representation, no matter how accurate and honest, involves simplification, symbolization, and selective attention. Even when a map isn’t actively trying to deceive its readers, it still must reduce the complexity of the real world, emphasizing some features and hiding others. Compressing the round globe onto a flat sheet of paper, and converting places, people, and statistics into symbols, lines, and colors is a process inherently fraught with distortion. […]

In Bending Lines: Maps and Data From Distortion to Deception, we explore the many ways in which maps have “bent” reality and created a picture of the world that is oftentimes more real than reality itself. Some of the maps in this exhibition are deliberately nefarious, created by people or institutions who are trying to mislead or persuade. But for many of the others, the relationship between map and truth is more ambiguous. Some maps dim a certain type of truth in order to let another type of interpretation shine through, while others classify and categorize the world in ways that should raise our skepticism. And for some of the maps shown here, the persuasive goal isn’t trickery but liberation, as they seek to raise awareness of truths that were previously obscured or oppressed.

This exhibition was to have launched last month, but thanks to the pandemic has had to go fully online. Tackling everything from persuasive cartography to map projections to the sort of thing Mark Monmonier talks about in How to Lie with Maps, it’s an enormous undertaking in more than one sense. CityLab’s Laura Biss interviews the Leventhal’s curator, Garrett Dash Nelson, about the exhibition.

Update, 2 July: Harvard Magazine looks at the exhibition.

The Topologist’s Map of the World

The Topologist’s Map of the World

Tom created the Topologist’s Map of the World to show how countries connect to each other. Deliberately emulating the style of a T-O map, Tom started with a Voronoi diagram and finished the map in Inkscape. Exclaves are ignored (too complicated), and islands encircle the rest of the map. Among Tom’s observations: “Some countries get really distorted—mostly when they find themselves near the centre of a continent. I’d often thought of Germany as the centre of Europe, but here, Austria and Hungary get really stretched out because they end up bordering countries on opposite sides of the continent.” [r/MapPorn]

Tim Robinson, 1935-2020

Published on by Jonathan Crowe

Tim Robinson, cartographer and chronicler of the Irish regions of the Aran Islands, the Burren and Connemara, died of complications from COVID-19 on 3 April 2020; he was 85. “Generations of tourists have been guided and enthralled by his marvellous maps of these radiant places,” writes Fintan O’Toole in the Irish Times. “But it is his astonishing books, the two-volume Stones of Aran and the Connemara trilogy, that will stand as timeless monuments to a genius who combined the linguistic brilliance of a poet with the precision of the mathematician he once was.” Also in the Irish Times, Paul Clements looks at Robinson’s idiosyncratic cartography: “For Robinson everything was mappable, and for good measure, he added a few puzzles, doodles and whimsies.”

Mapping the Global Imaginary

Published on by Jonathan Crowe

In February 2019 a conference on the blurred line between factual and fictitious mapping in history, Mapping the Global Imaginary, 1500-1900, took place at Stanford University’s David Rumsey Map Center. Which I somehow missed. But no worries: videos of the conference panels are available online (see above for the first one), as is the talk by the keynote speaker, Sumathi Ramaswamy.

Maps of Antarctica at the British Library

Two recent posts at the British Library’s Maps and Views Blog provide “a whistle-stop tour through maps held in the British Library that chart Antarctica’s gradual emergence from obscurity into light.” The first covers maps of Antarctica through the nineteenth century, when the continent went from unknown to unexplored; the second the twentieth century, where maps of the continent “[reflect] the switch made by cartography to digital data from the latter part of the twentieth century.”

Tom Patterson’s Physical Map of the Contiguous United States

Physical Features Map of the Contiguous United States

Tom Patterson’s latest project is a map of the physical features of the contiguous United States.

This map showcases physical features—mountains, plains, rivers, lakes, etc.—of the 48 contiguous US states. Map colors reflect natural environments across the continent from the forested east to the snowcapped Rockies to the desert southwest. You will also find a smattering of cities and faint state lines for reference.

Emphasis on smattering: there are only enough human features—cities and borders—to orient the reader; the focus is on bodies of water and landforms.

It’s freely available and in the public domain: it can be downloaded, shared and modified.

‘The Monsters of Maps’: A Video About Caricature Maps

Published on by Jonathan Crowe

“The Monsters of Maps,” a 10-minute video by Richard Tilney-Bassett, explores the late-19th- and early-20th-century phenomenon of “serio-comic” or caricature maps, which are no stranger to us here. In the video Richard wonders what a modern-day caricature map would look like; I’d point him to the work of Andy Davey (see here and here).

Censorship and the Ordnance Survey

Published on by Jonathan Crowe

A blog post from the National Library of Wales explores how sensitive military and industrial sites were omitted from the published versions of Ordnance Survey maps.

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.

Engravers: The Unsung Heroes of Mapmaking

Published on by Jonathan Crowe

The Bodleian’s Map Room Blog (no relation) has a post about the “unsung heroes” of mapmaking: the engravers.

Until the nineteenth century, virtually all printed maps were produced by engraving the map on a sheet of copper—or later on, steel—as a mirror image of how the finished map would look. The plate was then inked and the image printed onto a sheet of paper in a printing press. This was incredibly skilled work, but often only very discreetly acknowledged, the engraver’s name appearing in tiny, modest letters in the bottom margin.

Identifying the engravers for cataloguing purposes—something a library like the Bodleian tries to do—can be a challenge.

The Guardian Interviews Martin Vargic

Detail from Martin Vargic, “Britannia Under the Waves.”

Yesterday’s Guardian had an interview with Slovak designer Martin Vargic, whom you may remember for his 2015 book Vargic’s Miscellany of Curious Maps [Amazon, Bookshop]. In this interview, Vargic talks about his various projects—he’s been doing this since he was eight, and was a teenager when Miscellany was published. One imagines there’s a bit of a career ahead for him.

Meanwhile, Andrew Liptak wrote about Vargic’s “Map of the Literature II” at Tor.com last October. In November Vargic’s second book, Vargic’s Curious Cosmic Compendium, came out in the U.K. from Michael Joseph.

‘With Savage Pictures Fill Their Gaps’: Chet Van Duzer on Horror Vacui

Published on by Jonathan Crowe

Chet Van Duzer’s presentation about the lack of empty spaces on old maps—horror vacui—at the November 2017 meeting of the New York Map Society has now been uploaded to YouTube.

As I’ve said before, the subject of empty spaces on maps is of considerable interest to my own research on fantasy maps: fantasy maps tend to be full of empty spaces not germane to the story, whereas real-world maps were covered in cartouches, sea monsters, and ribbons of text. As a result I’m very interested in what Van Duzer has to say about the subject, and have been looking for something exactly like this recorded talk for some time.

I wasn’t disappointed. Van Duzer lays out, with some particularly over the top examples, how empty spaces on maps were consumed (his term) by text, ships, sea monsters and other embellishments that were designed for that very purpose. Some of those embellishments were absolutely enormous, others curiously redundant: a single map does not need four identical scales or a dozen or more compass roses, for example. “Everything we’re seeing here was a choice on the part of the cartographer,” he says at one point; “all this information could be disposed differently.”

How to Make an Illustrated Map

Five Squares + One Triangle in My Neighborhood (Nate Padavick)

In the travel section of yesterday’s New York Times, map illustrator Nate Padavick offers a way to make lemonade from travel-restriction lemons with a short guide to making an illustrated map (pictorial map, map illustration—the terms are roughly interchangeable) of a favourite place—a neighbourhood, a vacation spot, “a place you’ve never been.”

The rigid and scientific rules of cartography simply do not apply here! Nope. While an illustrated map is often a wildly useless tool for providing directions, it can be a beautiful and highly personal reflection of a place you, friends and family know quite well. It can tell a story, a personal history, or be a unique lens through which one can experience a special place. An illustrated map can be loose and hand-drawn, filled with fun drawings and doodles that together make a sometimes inaccurate, but always spot on record of a memory or a place from one’s own perspective.

Not the first time we’ve seen map art as lockdown activity. Previously: Maps from Isolation; CityLab Wants Your Hand-Drawn Quarantine Maps; Still More Coronavirus Maps; Fuller’s Quarantine Maps.

A U.S. Army Film from 1971: ‘Mapping a Better Tomorrow’

Published on by Jonathan Crowe

“Mapping a Better Tomorrow” is a 30-minute film produced in 1971 to explain the work of the U.S. Army Topographic Command (TOPOCOM). After explaining maps from first principles, it covers the state of the art in terms of cartography, computer mapping, photogrammetry and surveying circa 1971, including the production of topographic maps, maps of the Moon and maps of, erm, southeast Asia. Since U.S. government publications are public domain, it’s available in several locations, including the Internet Archive (above), DailyMotion and Vimeo.

TOPOCOM itself had a short history. Created in 1968 (PDF) as the successor to the U.S. Army Map Service, it lasted less than four years before being merged into the Defense Mapping Agency (DMA) in 1972. Which in turn was merged into the National Imagery and Mapping Agency (NIMA) in 1996. Which in turn was renamed the National Geospatial-Intelligence Agency (NGA) in 2003.
