Literary Maps Exhibition at Harvard’s Houghton Library

Landmarks: Maps as Literary Illustration, an exhibition of literary and fantasy maps at Harvard’s Houghton Library, is free to the public and runs through 14 April 2018. “Presented in conjunction with the bicentenary of the Harvard Map Collection, this exhibition brings together over 60 landmark literary maps, from the 200-mile-wide island in Thomas More’s Utopia to the supercontinent called the Stillness in N. K. Jemisin’s The Fifth Season. Visitors will traverse literary geographies from William Faulkner’s Yoknapatawpha County to Nuruddin Farah’s besieged Somalia; or perhaps escape the world’s bothers in Pooh’s Hundred Acre Wood.” Atlas Obscura has more on the exhibition, along with a selection of some of the maps it presents.

The Gerrymanderers

When we talk about gerrymandering, about redrawing the political map to favour one’s own party at the expense of another, we talk a lot about the maps themselves. The mapmakers, not so much. Check out this New York Times article on the political consultants who do the redrawing; it focuses on the electoral map of Maryland, which like several other states’ maps is the focus of a court challenge. The process has become even more refined as more and more data becomes available to feed into the redistricting maw.

The Times article points to a similar, earlier article that appeared in the October 2012 issue of The Atlantic and goes into even more depth: “The League of Dangerous Mapmakers.” [Leventhal]

Transport for London’s Historical Archive of Car Line Diagrams

Bakerloo Line CLDs (Transport for London)

IanVisits has stumbled across Transport for London’s cache of car line diagrams (CLDs)—the linear maps that appear inside each train car. The TfL page includes CLDs ands CLD stickers for all lines going back to 1996; each line has its own PDF file that contains every iteration of its diagram, one per page. “No one will care about this whatsoever,” says IanVisits. IanVisits is, I suspect, wrong. [WMS]

Non-Anonymized Strava User Data Is Accessible

More on the privacy issues regarding Strava’s global heat map and its customer data. Now Wired UK is reporting that Strava’s data isn’t anonymous. Because you can compare your results with nearby users, all it takes is a local GPS tracklog—which can be created out of whole cloth, as Steve Loughran’s blog post demonstrates—to see detailed information about users. Wired UK:

By uploading an altered GPS file, it’s possible to de-anonymise the company’s data and show exactly who was exercising inside the walls of some of the world’s most top-secret facilities. Once someone makes a data request for a specific geographic location—a nuclear weapons facility, for example—it’s possible to view the names, running speeds, running routes and heart rates of anyone who shared their fitness data within that area.

The leaderboard for an area, the Guardian reports, can be extremely revealing. “The leaderboard for one 600m stretch outside an airbase in Afghanistan, for instance, reveals the full names of more than 50 service members who were stationed there, and the date they ran that stretch. One of the runners set his personal best on 20 January this year, meaning he is almost certainly still stationed there.”

Which makes the security issue regarding military personnel using fitness trackers even worse than simply the anonymous aggregate of the routes they take. Yes, this is very much an unintended and unforseen consequence of relatively innocuous social sharing bumping up against operational and personal security protocols; and it’s as much on military personnel to, you know, not use GPS-enabled devices that upload your location to a third-party server as it is on companies to have clear and effective privacy controls. This is very much the result of a whole lot of people not thinking things through.

Geographical Fun: The Teenager Who Drew Serio-Comic Maps

We’ve seen “serio-comic” or caricature maps before, most of them dating from the late 19th and early 20th centuries, but Caitlin takes us behind the scenes with a story about one of the artists behind such maps. The twelve maps published in Geographical Fun: Being Humourous Outlines of Various Countries (1868) were the handiwork of a 15-year-old teenager named Lilian Lancaster, who originally drew them to amuse her ill brother. Which is a great and surprising twist. The accompanying text (an introduction and accompanying verses) was by William Harvey (under a pseudonym), who tried to make an educational case for such maps (as one did).

War Games Disrupting GPS in the Western U.S.

Meanwhile, aerial war games conducted by the USAF over Nevada will disrupt GPS in the western U.S. over the next few weeks. As The Drive reports, “the USAF is going to blackout GPS over the sprawling Nevada Test and Training Range to challenge aircrews and their weaponry under realistic fighting conditions. The tactic will spill over throughout the region, with warnings being posted stating inconsistent GPS service could be experienced by aircrews flying throughout the western United States.” The disruptions will occur through 16 February.

Strava Heat Map Reveals Soldiers’ Locations

Strava is a mobile fitness tracking app that uses GPS data from phones and watches. It has access to a lot of data, and has been using that data to create a global heat map showing the paths taken by its cycling and running customers. The map’s most recent update, last November, aggregates user data through September 2017. But analyst Nathan Ruser noticed a problem: in places where local Strava use is low, the map can reveal the paths of people from wealthy western countries—for example, soldiers at U.S. military bases overseas, whether they’re patrolling or simply exercising. (U.S. troops are encouraged to use fitness trackers.) Which is to say, suddenly Strava is a security problem. Details at BBC News and the Washington Post.

Family’s Maps Exhibited in Fort Lauderdale

A Florida businessman’s private map collection is the subject of an exhibition at Nova Southeastern University in Fort Lauderdale. 100 Maps That Changed the World: Discovery of the Americas and the Establishment of the United States, featuring maps from the 15th through the 18th centuries owned by the Asbury family, runs until 31 January at the Alvin Sherman Library. The Sun-Sentinel has a profile of Neal Asbury, whose map collecting jones hit in his 20s. [WMS]

Redrawing Congressional Districts in Pennsylvania

The New York Times

In gerrymandering news, the Pennsylvania Supreme Court threw out the state’s congressional district map earlier this week, ordering the 18 districts—which have been called some of the most gerrymandered in the United States—to be redrawn in time for the 2018 elections. The New York Times explores how the Pennsylvania map could be redrawn in two ways: “One is a neutral map, the kind that might be drawn by a nonpartisan committee. The other is an adventure in extreme gerrymandering that aims to maximize the number of Republican-held seats.” (See above.) Meanwhile, if you live in the state, you might want to take a crack at remapping the districts yourself. Draw the Lines, a project by a nonpartisan watchdog group called the Committee of Seventy, will be holding a contest to redraw the state’s districts later this year.

A Beginner’s Guide to Map Collecting

Two things about CityGuide’s beginner’s guide to map collecting. One, it’s not so much for beginners as written by a beginner; the author, Chris Sharp, is recounting his own journey into map collecting. Which brings me to the other thing: what kind of map collecting he’s talking about, which is to say, the “collecting all the OS Landranger maps” kind of map collecting, not the “paying exorbitant sums for a rare and ancient map that might be a forgery or sliced out of a volume from a library’s rare books collection” kind of map collecting. I don’t want to invoke Dunning-Kruger here, but I’m not sure he knows how much more there is out there. I suspect that he’s going to find out. Not being British myself, I don’t know to what extent Ordnance Survey maps are the gateway drug to a serious map collecting jones, but I have my suspicions. [WMS]

High-Resolution Sea Floor Maps of the Great Barrier Reef

The Australian government has released high-resolution sea floor map data of the Great Barrier Reef; the data improves the view of the relief by a factor of eight, from 250-metre resolution to 30-metre resolution. The result of a collaboration between James Cook University, Geoscience Australia and the Australian Hydrographic Service, the data “can be used for policy, planning and scientific work. For example, this data is an important input for oceanographic modelling, which we can use to enhance our knowledge of climate change impacts, marine biodiversity, and species distribution.” Press release, data files.

Dan Bell’s ‘Tolkien-Style’ Maps of the Lake District

Dan Bell, “The Lake District National Park.” Giclée print.

Maps of real places done up in the style of fantasy maps are a thing, as those who have been following along will know by now. I’m planning a dedicated page on the subject in the Fantasy Maps section. That page will have to include Dan Bell’s maps of the Lake District—maps, he says, “that resemble the iconic style of J. R. R. Tolkien.” His maps have suddenly got a bit of media attention, which is atypical for this sort of project: BBC News, The Westmoreland Gazette. They resemble more the maps done for the Lord of the Rings movies than the maps created by Christopher Tolkien or Pauline Baynes: one tell is the triple-dot diacritic above the a, which is used in the movie maps and comes from Tolkien’s Elvish script. Bell, a 25-year-old “ordinary guy” from the Lake District, is selling prints of the maps online. [Kenneth Field]

Seymour Schwartz at 90

Today is the 90th birthday of Seymour Schwartz, surgeon, map collector and author of books of map history (The Mismapping of America and Putting “America” on the Map, among others). It’s a milestone noted by the Rochester Democrat & Chronicle, which gives considerable attention to his long medical career—a side of him that those of us into maps may know less about. [WMS]
