Birds Discover Longitude

Eurasian reed warblers don’t need no stinkin’ marine chronometers. A new study suggests that the migratory birds make use of magnetic declination to determine longitude, “at least under some circumstances under clear skies. Experienced migrants tested during autumn migration in Rybachy, Russia, were exposed to an 8.5° change in declination while all other cues remained unchanged. This corresponds to a virtual magnetic displacement to Scotland if and only if magnetic declination is a part of their map. The adult migrants responded by changing their heading by 151° from WSW to ESE, consistent with compensation for the virtual magnetic displacement.”

Not, it would seem, accurate enough for the species to earn a chunk of the Longitude Prize, and it’s not like John Harrison should have been messing about with birds instead of clocks, but interesting all the same. [GeoLounge]

Nowherelands

A book I missed hearing about earlier: Bjørn Berge’s Nowherelands: An Atlas of Vanished Countries 1840-1975 (Thames and Hudson, October 2017). Another in the line of books about obscure, unusual and out-of-the-way places, this one focuses on countries that really did exist, but only for a little while. From the publisher:

Some of their names, such as Biafra or New Brunswick, will be relatively familiar. Others, such as Labuan, Tannu Tuva and Inini, are far less recognizable. But all of these lost nations have fascinating stories to tell, whether they were as short-lived as Eastern Karelia, which lasted only a few weeks during the Soviet–Finnish War of 1922, or as long-lasting as the Orange Free State, a Boer Republic that celebrated fifty years as an independent state in the late 1800s. Their broad spectrum reflects the entire history of the 19th and 20th centuries, with its ideologies, imperialism, waves of immigration and conflicts both major and minor.

The Red Atlas

During the second half of the twentieth century, the Soviet Union’s military and civilian cartographers created topographical maps of the entire world of a very high standard of quality and accuracy. How they did so, and why, remains in large part a mystery, one that John Davies and Alexander J. Kent’s new book, The Red Atlas: How the Soviet Union Secretly Mapped the World (University of Chicago Press, October) fails to solve completely.

The Red Atlas is not the definitive history of those Soviet mapping efforts because so much about those efforts remains a secret. The only reason we know about them is because, in the wake of the collapse of the Soviet Union, so many physical copies of those once-highly secret maps fell into the hands of map collectors. The Red Atlas talks about that: for more than a decade, Davies and Kent have been studying those maps. (I’ve been following their work. See the links at the bottom of this post for my earlier posts on the subject.) What they know about the Soviet mapping efforts—sources, methods, their reason for doing it—is extrapolated from the final product of those effort: the maps. The Red Atlas is above all else an exercise in cartographic forensics.

London Underground Architecture and Design Map

Blue Crow Media’s latest map of urban architecture is the London Underground Architecture and Design Map, a collaboration between transit system guru (and friend of The Map Room) Mark Ovenden and photographer Will Scott. “The guide includes a geographical Underground map with featured stations marked, with corresponding photography and details on the reverse along with tips for where to find unique and unusual signage, roundels, clocks, murals and more. The map is protected by a slipcover featuring a distinctive die cut roundel.” Costs £9. More at Mapping London.

Pledge Break

If you like what I do here and you have a couple of extra dollars, pounds, euros or kroner lying around, this would be an awfully good time to send them The Map Room’s way: sent directly to me via Ko-Fi or, if you don’t trust me to handle money, directly to my web hosting bill.

That bill, by the way, is about to go up. This blog has been on the edge of need-to-upgrade/don’t-need-to-upgrade since I restarted it nearly two years ago, but it looks like I’ve done all the optimizations I can under shared hosting. It’s time to get a VPS. Which will cost a little more.

Given the dreadful state of online advertising (my ad income is one-twentieth what it was a decade ago), blogs like The Map Room will increasingly have to rely on reader support. I’m not very comfortable with periodic pledge breaks like these, so I’m exploring the idea of setting up a membership system, which if I go for it would launch some time in early 2018. The trick with me using systems like Memberful or Patreon is that a blog like The Map Room isn’t really geared toward members-only content: I’m a link aggregator, not a content producer. But if I can make this project a bit more financially viable, I can spend time on it rather than other work.

Your support, as always, is not required, but it is deeply appreciated.

James Clark’s Revised Map of Current and Proposed Railways in Southeast Asia

James Clark

James Clark has updated his map of current and proposed railways in southeast Asia (see previous entry). The new version clearly delineates between current and proposed lines. “The black lines on the map represent railways that are currently operating, while the red lines are proposed lines. As with the subway map, proposed can mean anything from lines currently under construction, in feasibility study stage, or an on-the-record election promise from a pork-barrelling politician.”

Londonist Mapped

Londonist Mapped: Hand Drawn Maps for the Curious Explorer came out last month from AA Publishing. (It’ll be out in North America next February.) Londonist describes their book thusly: “The book presents dozens of beautiful maps of the capital, from historic plans to specially commissioned art. Here you’ll find maps of lost Victorian buildings, little-known musical history, subterranean London and many more. The book also includes a reprint of our popular Anglo-Saxon London map.” I wonder if it includes “Bridges of London.” [WMS]

Future and Alternate Melbourne Transit Networks

Adam Mattison

Geospatial scientist Adam Mattison also dabbles in maps of a more speculative bent, including maps imagining Melbourne’s future transit network, including a tram network map of 2048, a metro map of 2070, and the above train network map of 2070. There’s some alternate history as well: maps of transit systems that might have been, but weren’t. For some reason this was picked up by the news section of Australian property and real estate portal Domain. [WMS]

More Fantasy Map Generators

Maps Mania has a roundup of fantasy map generators—applications that generate maps of imaginary cities or landscapes algorithmically. Sometimes even with names. Two of them I’d previously heard of: Uncharted Atlas, a Twitter bot that tweets out a new map every hour, and the Medieval Fantasy City Generator, which generates a random medieval city layout. Two were new to me: Azgaar’s Fantasy Map Generator, which comes complete with documentation and an accompanying blog; and Oskar Stalberg’s City Generator, which doesn’t.

I’ve said it before, and I’ll say it again. If fantasy map generators can produce a map that is at least credible in comparison to the human-made product, what does that say about that human-made product in terms of the imagination and creativity that went into it?

Picturing America: The Golden Age of Pictorial Maps

With Picturing America: The Golden Age of Pictorial Maps (University of Chicago Press, March 2017), Stephen J. Hornsby makes the case for the pictorial map as a distinct and significant genre of mapmaking that is worthy of study and preservation.

Because pictorial maps were artistic rather than scientific, Hornsby argues, they were ignored as a subject of cartographic study—“treated as ephemera, the flotsam and jetsam of an enormous sea of popular culture.”1 As such they have not been preserved to the same extent as more strictly cartographic maps. (Being printed on cheap acid paper didn’t help.) But as products of popular culture they were distinctive—and ubiquitous. “By World War II,” he writes, “pictorial maps had created a powerful visual image of the United States and were beginning to reimagine the look of the world for a mass consumer audience.”2 They were so prevalent, I suppose, that they were invisible. Taken for granted. It frequently falls to the historian of popular culture to point out that the common and everyday is, in fact, significant. That’s what Hornsby is doing here.

Osher Map Art Exhibition Opens Today

Opening today at the Osher Map Library in Portland, Maine and running until 10 March 2018, an exhibition of cartographic art called Go Where the Map Takes You: The Intersection of Cartography and Creativity. “Maps show many versions of our world, for many purposes, but their simplest purpose is to show the way from one place to another. The artists in this exhibition have used the techniques of mapping, and maps themselves, to show the way to the metaphorical and the metaphysical. We invite you to explore these artworks and see where they lead you.” Featuring several familiar artists.
