The Tabula Peutingeriana is a cartographic marvel—a 13th-century copy of what is supposed to be a 4th- or 5th-century diagram of the Roman road network— but it’s not exactly easy for the modern map reader to parse. The Tabula Peutingeriana Animated Edition abstracts the map into a diagram. It’s part of Jean-Baptiste Piggin’s attempts to draw meaning out of the map; for more of which see his posts about the Tabulahere.
Canadian Geographic maps the decline of Canada’s caribou populations. “All of Canada’s caribou subspecies have increasingly been in the news as the animal’s national population, which once numbered in the millions, has declined drastically and quickly to little more than a million today. Experts are concerned some populations may not survive the threats they’re facing. One herd, British Columbia’s South Selkirk, had just three females left in April 2018.” [r/MapPorn]
All Over the Map: A Cartographic Odyssey (National Geographic, 30 October) is the book version of Betsy Mason and Greg Miller’s eponymous blog for National Geographic. Kenneth Field reviews the book on his blog; he notes that their background—journalists, not map professionals—makes for a refreshing perspective: “They aren’t burdened by having a list of maps that have to go in their collection (you know the ones … we all know them). They have chosen what they want to go in, and so their list is, in the main, a fresh list and contains many maps you’re unlikely to have seen.”
Another review of Thomas Reinertsen Berg’s Theatre of the World, this time from Geographical magazine, which calls it “a deeply idiosyncratic history of cartography, geography and surveying, from Stone Age symbols to Digital Age interactive maps. The meandering text features digressions on everything from Sumerian counting systems and ancient origin myths to Scandinavian border disputes, as well as some half-hearted imagined depictions of historical figures at work.” Theatre of the World came out in the U.K. from Hodder & Stoughton in September; the American edition will be published by Little, Brown in December. See previous entry.
Speaking of Washington, the D.C. Underground Atlas is a project to map all the tunnels under the city: utility, transportation and pedestrian tunnels alike, from metro and water tunnels to the underground corridors connecting congressional buildings. The maps are presented as Esri Story Maps and there’s lots of accompanying text. The project is the brainchild of Elliot Carter, who is profiled by CityLab and the Washington Post: both pieces reveal one challenge in mapping the underground infrastructure of Washington—getting past security concerns.

Atlas Obscura looks at the cartographic work of early American educator Emma Willard, who in 1829 published a series of maps to accompany her History of United States, or Republic of America, a school textbook that came out the previous year. The book was an early example of a historical atlas: it was “the first book of its kind—the first atlas to present the evolution of America.”
The web comic xkcd has done maps before (and I’ve covered most of them) but Friday’s iteration was a departure all the same: an interactive map of the challengers in the 2018 U.S. midterm elections: the larger the candidate’s name, the more significant the office and the better their odds of winning. Remember, these are only the challengers: no incumbents are listed.
Stanford University Libraries’ collection of Office of Strategic Services Maps: The OSS Map Division, directed by Arthur H. Robinson, produced nearly 6,000 maps before the OSS was disbanded in 1945. Stanford has digitized and posted around 700. These maps focus on wartime theatres of operation and deal with subjects like industrial capacity, ports, railroads and other strategic interests.

Bloomberg maps what political ads are talking about in 210 local television markets, and finds some intriguing patterns in terms of what each party chooses to focus on in each local market. [Nathaniel Rakich]
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]
In Scotland: Defending the Nation (Birlinn, 4 October), Carolyn Anderson and Christopher Fleet “explore the extraordinarily rich legacy of Scottish military mapping, including fortification plans, reconnaissance mapping, battle plans, plans of military roads and routeways, tactical maps, plans of mines, enemy maps showing targets, as well as plans showing the construction of defences. In addition to plans, elevations and views, they also discuss unrealised proposals and projected schemes. Most of the maps—some of them reproduced in book form for the first time—are visually striking and attractive, and all have been selected for the particular stories they tell about both attacking and defending the country.”
There’s a lot of stuff relevant to our interests on the website of the University of Richmond’s Digital Scholarship Lab, and it’s hard to know what to begin with. One of the more recent projects, which CityLab saw fit to link to yesterday, is an interactive map showing elections to the U.S. House of Representatives from 1840 to 2016. It’s the kind of project that the user can get very, very lost in. In addition to the usual map of U.S. congressional districts, the site can also visualize the districts as a dot map to minimize the empty-land-doesn’t-vote problem (they call it a cartogram: it isn’t). There’s also a timeline showing the overall results over time at a glance; selecting a district gives shows how the district voted in past contests as a line graph. In other words: quite a lot of data, economically presented.
CBC News’s interactive map of last month’s provincial election in Quebec gives us a detailed look at who won each poll, and by how much (percentages, not raw numbers), and compares those results with those from the 2014 election. The map highlights where the pockets of support for each of Quebec’s parties can be found; comparing those pockets with the 2014 results is quite revealing. (The 2018 election was a bit of a watershed, as support bled from the established Liberal Party and Parti Québecois to the upstart CAQ, which won, and Québec Solidaire.) Here’s the accompanying story from CBC News.
FiveThirtyEight looks at the polling data for the upcoming 2018 midterm elections and imagines the results for the U.S. House of Representatives if only women, men, nonwhite voters and white voters by education level voted. It’s a thought exercise they’ve indulged in before, with the presidential race in 2016, and it serves to indicate the demographic divide in voting intentions. (Cartographically, the maps suffer from the usual problem of U.S. election maps of congressional districts—large, sparsely populated districts in the middle of the country dominate the map.)
