Jonathan Crowe blogs about maps at The Map Room. His essays and reviews have been published by AE, Calafia, The New York Review of Science Fiction, the Ottawa Citizen, Strange Horizons and Tor.com. He lives in Shawville, Quebec.
Alejandro Polanco’s latest Kickstarter project is the Pandemic Atlas. The idea, he says, “is to gather the most relevant information about the pandemics and major epidemics that have hit humanity throughout history to create an atlas in the visual style of my Minimal Geography project.” In 130 pages, the Pandemic Atlas explores major epidemics throughout history, and includes general chapters on heath subjects. The project’s inception actually predates the COVID-19 pandemic; it was initally inspired by the 100th anniversary of the 1918 pandemic, but at the time there was not much interest in the topic. Fast forward today, when an atlas about historical pandemics is just a little too topical.
The Pandemic Atlas Kickstarter runs through 24 February (it’s already met its goal). €20 gets you a digital copy of the atlas, €60 adds the hardcover.
In an interview with Atlas Obscura’s Max Ufberg, legendary ski resort map artist James Niehues (no stranger to us here at The Map Room: previously) discusses some of the challenges involved in creating his paintings. For example:
What’s the most challenging aspect of the work? Showing all the trails in the most understandable and navigational way. It may not always be in one view, but I strive for the single view because it leaves no doubt about any trail connections or direction. Many mountains have slopes on more than one face, which requires manipulating the features to show the back side with the front on a flat sheet of paper. This has to be done with care since skiers will be referring to the image to choose their way down; all elements have to be relative to what they are experiencing on the mountain.
A new article on the life and career of Marie Tharp, written by our friend Betsy Mason, was published by Science News earlier this month. Plenty has been written about Tharp, whose work mapping the ocean floor helped provide the evidence for continental drift: numerous articles, a 2012 biography, two books for children just last year. But that doesn’t mean that there aren’t still people who still haven’t heard of her, and should.
GPS signals are relied upon by critical parts of our infrastructure, from transportation to communications to agriculture to financial markets. But those signals are easily spoofed or jammed and, at least in the United States, have no real backup (despite legislation mandating one by last year). Kate Murphy’s opinion piece in the New York Times not only serves as a summary of the problem, and a warning, it also does so in the most mainstream of newspapers: most of what I’ve read on the subject has been in the business, tech and science media. More people will see this. [MAPS-L]
Kenneth Field has posted his favourite maps from the past year—something he’s been doing since 2013. Quite a diverse set, from the Johns Hopkins coronavirus dashboard to a Lego model of Manhattan: you won’t have seen all of them.
The Closest Stars is the latest astronomical map produced as part of Kevin Jardine’s long-running Galaxy Map project: it shows stars within 10 parsecs (32.6 light years) of our solar system. (Earlier maps covered much more territory: this map goes out to 6,000 pc.)
It’s fascinating, and has a lot of interesting information, but there’s a problem. Like all maps, it reduces three dimensions to a flat plane; as such it distorts the distance of stars that are substantially above or below the galactic plane but not very far away on the x or y axis. Take Beta Comae Berenices: it’s 9.18 pc away and as such should be at the edge of the map, but because it’s 9.18 pc away on the z axis, at nearly a right angle to the plane, it appears on the map as one of the closest stars. The distance above or below the plane is marked in parentheses, but that’s not enough: a label can’t compensate for a misleading position on the map. On the smaller-scale maps this isn’t as much of an issue, because the galaxy is more or less a disk or a lens, but within a 10-pc radius? This isn’t the right projection for the job.
The update also includes Look Around, and not just in a few locations. Elsewhere in the world, Look Around is being rolled out on a city-by-city basis; in Canada it’s far more comprehensive. How comprehensive? I live in a village of 1,600 people not far from Ottawa, and my house is on it. (Based on the state of our gardening, the imagery was taken sometime in 2019, either in late summer or early fall.) Major highways are also included, not just cities. Justin O’Beirne looks at the coverage areas.
Once a design classic, the map has been ugly, and getting uglier, for a while. The rot started to set in with the baffling decision to show the fare zones using a series of irregular grey polygons that make it look like the familiar shape of the Tube network had been painted against the backdrop of the sort of artwork you’d find lining the corridors of a Gatwick Airport hotel sometime in the late 1980s.
But the bigger problem is that Transport for London have thrown more and more services onto the map without any apparent consideration for what it might need to change in order to accommodate them. Most of the map is still given over to the northern half of London, even though a growing share of the services it shows (the Overground, Tramlink, now Thameslink) are south of the river.
Kenneth Field explores (and dismantles) the mythology around John Snow, the discovery that cholera was spread by water, the role of the famous cholera map and whether it revolutionized disease mapping. Depending on what you know about the subject—if, for example, you got what you know from an episode of Map Men—what you know is more myth than history: the map came after the Broad Street outbreak, it was not by any means the first example of disease mapping, and John Snow wasn’t the map’s cartographer. Field:
The mythology surrounding his work, the 1854 epidemic, and specifically the role of the map are a fine story, but much of it is retold according to the version many seem happy to believe rather than what really happened. But the real story is just as interesting. There are plenty of excellent longer form discussions of the story in which you may be interested. In particular, Kari McLeod’s excellent article that goes into detail about the various myths, and an article by Tom Koch and Kenneth Denike also goes into detail about the true order of events.
Google announced earlier this month that their updated Street View app for Android—as an Apple user I had no idea that Street View was a separate app on Android—now supports user-contributed photos to Street View. “After you record your images and publish them via the Street View app, we automatically rotate, position and create a series of connected photos. We then place those connected images in the right place on Google Maps, so your new Street View can be found in the exact location where it was taken for others to see and explore.” The idea is to supplement Google’s imagery where it’s thin on the ground. This beta feature requires an ARCore-compatible Android device and is only available in a few areas for now: Toronto, New York, and Austin TX (presumably for testing purposes), as well as Costa Rica, Indonesia and Nigeria.
Last month it was reported that the X-Mode software development kit, used by many apps, was collecting and selling user location data, with the U.S. military among the buyers. In response, earlier this month both Apple and Google gave developers a deadline to remove X-Mode from their apps: seven days in Google’s case, fourteen in Apple’s. Apple found 100 apps that contained the code; X-Code claims 400 apps on all platforms, tracking 25 million devices in the U.S. and 40 million elsewhere. The Wall Street Journal story is behind a paywall; see The Verge and MacRumors for summaries.
It tries to address something that I find frustrating about election maps: Very few of them do a good job of showing where voters are. […] There are more Trump voters in California than Texas, more Biden voters in Texas than New York, more Trump voters in New York than Ohio, more Biden voters in Ohio than Massachusetts, more Trump voters in Massachusetts than Mississippi, and more Biden voters in Mississippi than Vermont.
In a long piece for Canadian Geographic that came out in May 2019, Aaron Kylie explores a subject that really should get more attention: maps in video games. “Maps have long played a critical role in video games, whether serving as the primary user interface, a player reference tool or both. This virtual cartographic world (and its remarkable Canadian connections), however, remains widely unheralded, even as mapping has become increasingly important to many games.” The focus of the article is Assassin’s Creed Odyssey, though Kylie touches on other games as well.
