Apple Maps Updates Canada

Published on by Jonathan Crowe

Apple’s new maps, first announced in 2018, have finally come to Canada: they went live country-wide on 10 December. See coverage from AppleInsider and MacRumors; Justin O’Beirne compares the new maps with the old.

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.

Canada is the fourth country to get the new maps: Ireland and the U.K. got them in October.

Tube Map Adds Thameslink Stations, Becomes More Even Complicated

Published on by Jonathan Crowe
The new temporary Tube map
Transport for London

Complaints that London’s Tube map has gotten too complicated are not new. So it’s not too surprising that Transport for London’s decision to add Thameslink rail services to the Tube map as of next month—temporarily, as a means of illustrating alternative travel options in the age of social distancing—is generating some heat. Thameslink already appears on TfL’s Tube and Rail map, but adding it to the Tube map proper is in some quarters seen as the final straw. Jonn Elledge at On London:

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.

Diamond Geezer has some specific questions about what the map is doing. On YouTube, Geoff Marshall is more positive.

The new map isn’t up on the TfL site yet, but can be seen here.

The Mythology of John Snow’s Cholera Map

Published on by Jonathan Crowe

John Snow's cholera map (detail)

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 Street View App Enables User-Uploaded Photos

Published on by Jonathan Crowe

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.

Apple and Google Ban Location Tracking SDK from Apps

Published on by Jonathan Crowe

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.

xkcd’s 2020 Election Map

Published on by Jonathan Crowe
Randall Munroe, “2020 Election Map.” xkcd, 16 Dec 2020.

xkcd did another map thing, so I have to post about it; it’s a rule. This time Randall revisits the design of the map he did for the 2016 U.S. presidential election, in which one figure represents 250,000 votes for each candidate. In a Twitter thread, he explains the rationale for the map:

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.

The ‘Critical Role’ of Maps in Video Games

Published on by Jonathan Crowe

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.

New Books from the University of Chicago Press

Published on by Jonathan Crowe

Two books from the University of Chicago Press

I received as review copies the following books from the University of Chicago Press, both now available:

In The Eternal City: A History of Rome in Maps, Jessica Maier “considers Rome through the eyes of mapmakers and artists who have managed to capture something of its essence over the centuries. Viewing the city as not one but ten ‘Romes,’ she explores how the varying maps and art reflect each era’s key themes. Ranging from modest to magnificent, the images comprise singular aesthetic monuments like paintings and grand prints as well as more popular and practical items like mass-produced tourist plans, archaeological surveys, and digitizations.” Amazon (Canada, UK) | Bookshop

Edited by Kären Wigen and Caroline Winterer, Time in Maps: From the Age of Discovery to Our Digital Era collects nine essays on the “ingenious and provocative ways” maps have attempted to depict time. “Focusing on maps created in Spanish America, Europe, the United States, and Asia, these essays take us from the Aztecs documenting the founding of Tenochtitlan, to early modern Japanese reconstructing nostalgic landscapes before Western encroachments, to nineteenth-century Americans grappling with the new concept of deep time.” Amazon (Canada, UK) | Bookshop

John Nelson’s Cassini Globe Ornament

Published on by Jonathan Crowe

Another year, another DIY papercraft globe ornament from John Nelson. “This ornament is a blending of NASA Visible Earth imagery and Esri/USGS Ecological Land Units. It uses the Cassini projection as six half-gores for the Northern and Southern Hemispheres, arranged in ArcGIS Pro.” In this blog post he shows how to print and assemble it.

Last year John released a set of Dymaxion ornaments. The year before that, a more complex geodesic globe ornament. This is now officially a tradition, John.

Mapping COVID-19 Hospitalizations

Published on by Jonathan Crowe

The thing that seems to worry authorities most about COVID-19 is its potential to overwhelm hospitals, at which point the mortality rate really begins to shoot up. In March, the University of Minnesota’s Carlson School of Management released the COVID-19 Hospitalization Tracking Project, which maps, on a county-by-county, basis, the percentage of hospital and ICU beds occupied by COVID-19 patients.

The Contiguous 41 States—Wait, What?

Published on by Jonathan Crowe
Contiguous 41 States (xkcd)
Randall Munroe, “Contiguous 41 States.” xkcd, 4 Dec 2020.

The thing about this xkcd cartoon is that at first glance it’s entirely plausible: Randall has done violence to state boundaries while maintaining the rough overall shape of the lower 48. He’s snipped out seven states without anyone noticing if they don’t look too closely.

Approved and Rejected Place Names in Ontario

Published on by Jonathan Crowe

CBC News explores how places in Ontario receive new names. There are hundreds of thousands of unnamed places in the province, and at the rate new names are being approved by the Ontario Geographic Names Board, it’s likely to stay that way: 85 new names have been approved in the past five years. On the other hand, 54 proposed names were rejected for not failing to meet the rules, which the article digs into:

The Ontario Geographic Names Board is guided by a strict list of naming rules. Submissions can’t have the same name as another nearby feature. Bad words are not allowed, nor are names that could seem like advertisements.

When it comes to people, a name won’t be considered unless that person has been dead for at least five years. Even then, there’s niche criteria. The person needs to have left a legacy either locally, provincially or nationally.

There’s even a rule about not naming something to commemorate a victim of an accident or a tragedy if they didn’t leave some sort of other legacy.

Fifteen Ways to Depict Elevation on Mars

Published on by Jonathan Crowe

How do you depict elevation on a map of Mars? Earlier this year, Daniel Huffman posted a roundup of hypsometric tints for Mars.

I have a peculiar hobby of collecting Martian hypsometric tinting schemes: those sets of colors that cartographers use to depict elevations on the Red Planet. It’s a fascinating cartographic frontier. While the classic (and somewhat flawed) way of showing Earth’s elevations is to use a color scheme that starts with green lowlands, and then proceeds through some combination of brown/yellow/orange/red until it reaches white in the highest areas, there’s no standard yet for Mars. Maybe centuries from now, one of the schemes below will become that standard.

Huffman looks at fifteen schemes in total in the post, and in this video on YouTube:

A History of Maps in Games

Published on by Jonathan Crowe

Matthew Edney explores the history of maps and games, beginning with the three basic forms of early map games: playing cards, board games, and puzzles, all of which had the “improvement” of youth as their aim. Over time game maps became more abstract (grids, simplifications) and puzzle pieces didn’t follow territorial boundaries. Edney doesn’t get very far into modern-day computer games, where the map becomes synonymous with the playing field, but that’s understandable: it’s too big a subject on its own (I’ve left it out of my fantasy map work for that reason).

Critical Tourist Map of Oslo

Published on by Jonathan Crowe

Markus Moestue’s Critical Tourist Map of Oslo turns the unremitting positivity of tourist maps on its head, painting the Norwegian capital’s landmarks and history in a bracingly negative light.

In most countries, what we are taught about our own nation in school does not correspond much to reality. And Norway is no exception. We are made to believe in myths surrounding our own nation and are given a perfect mirage of excellence and good intentions in our history lessons. Stories of abuse, greed and war are often swept under the carpet, and it seems that, by some twist of faith, we are born into the best country in the world, and that all other nations are beneath us. Is Norway really the most happy place, the most environmentally conscious, the most peace loving or the most ethical? Hardly!

In this map I aim to correct a few myths, point to some problematic aspects of  Norway and Oslo. And I wish for this map to be a contrast to the mindless commercially motivated map you’ll receive at the tourist information centre.

In a short video, Markus tries to stunt-distribute the map on the streets of Oslo:
