“I remember the first time I saw the New York City subway map. I called an Uber.” On her Urban Caffeine channel, Thea looks at the oft-maligned, controversial and complicated New York subway map. Her take is informed by her experience growing up in pre-GPS, pre-Google Maps Manila, which she frankly found easier to navigate; by contrast, she finds New York’s map too cluttered and information-dense and more in tune with the needs of New Yorkers than visitors and tourists.

Here’s a rail network map that shows the commuter rail lines of both New York City and Philadelphia. It’s by Evelyn Ivy, who explains on Mastodon that it took six months of work to complete. “Showing five different commuter rail systems (#CTRail, #MetroNorth, #LIRR, #NJTransit, and #SEPTA), this map depicts everywhere a passenger can get to by train from NYC or Philadelphia without using Amtrak.” (The keys are Trenton and New Haven, where you can hop from one system to the next.)

The impressive and/or insane thing about the New York City Tree Map is that it maps individual trees: now about 860,000 of them, all managed by the city’s parks department on city streets and in parks, down to the species and trunk diameter, which also means you can filter for those parameters, plus get most recent inspection and tree care data on specific trees. You can even favourite individual trees. If trees had social media accounts, they’d be here. [Bloomberg CityLab]

This roundtable discussion about The New York Subway Map Debate, a book about the April 1978 Cooper Union debate over the design of the New York subway map (previously) and related subjects, featuring John Tauranac himself (who participated in the 1978 debate), alerted me to the fact that an audio recording of that debate is available online. (A discussion about a book about a debate: this all feels a bit recursive.) [Kenneth Field]

At Worlds Revealed, the Library of Congress’s map blog, Tim St. Onge looks at, and provides the background on, a series of six maps prepared by Frederick E. Pierce for a report on living conditions in New York’s tenement housing in 1895, including a stunningly bizarre map of ethnic groups living in the city.

Pierce’s map of nationalities, however, is a more memorable, if confounding, centerpiece. Aiming to convey diversity among immigrant communities in New York, the map depicts the proportion of major “nationalities” in each sanitary district of the city. The result is a dizzying array of zigzag stripes and scattered points. As Pierce writes in his explanatory notes accompanying the Harper’s Weekly publication, the original map was produced in color and adapted to black and white for publication, but the reproduction “is almost as effective and quite as illustrative as the original.” Despite Pierce’s confidence, perhaps the average reader could be forgiven if they find the map to be more difficult to parse. In fact, the map seems to resemble more closely the dazzle camouflage, a design aimed at confusing the observer, used on British and American warships in the first half of the twentieth century.

The Wall Street Journal is reporting that New York’s Metropolitan Transit Authority is experimenting with new network maps that adopt a diagrammatic design that harkens back to Massimo Vignelli’s 1972 design, or (frankly) to designs used by most other transit systems. The new maps appear in nine subway stations side-by-side with geographically accurate maps of the MTA system, and embed QR codes so riders can submit feedback. If the maps are positively received, they could replace the MTA’s current network map—but New York being New York, and New York’s map wars being what they’ve been for the past fifty years or so, it’s anyone’s guess how this will shake out. More at Gizmodo.

New York’s Metropolitan Transit Authority has released a beta of a new digital subway map that aims to solve several problems at once. It shows train positions in real time and provides service bulletins in a single location. It also promises, says Fast Company’s Mark Wilson, to bridge the long-standing (and often acrimonious) divide between geographically accurate transit maps (Hertz) and diagrammatic network diagrams (Vignelli).

Here’s a video about how the new digital map came to be:

On Transit Maps, Cameron Booth has some criticisms of the map and its approach. “The main selling point of this map is that it has the clarity of a diagram but the fidelity of a geographical map—‘The best of both worlds!’ the articles happily proclaimed this morning—but the reality is more like ‘Jack of all trades; master of none.’ As much as I try, I simply can’t see any real benefit to this approach.”

Another point Booth makes, and I can confirm, is that the map isn’t just slow; it’s profoundly slow. On Safari it makes my current-generation, eight-core Core i7 iMac with 40 GB of RAM and a Radeon Pro 5500 XT feel like a snail; it’s a little better on Chrome, and on my third-generation iPad Air, but it’s still slow and janky and not very pleasant to use. Well, it’s a beta. But a beta that crawls on hardware faster than what most people own is, I’d gently suggest, not ready for release.

Rather than applying restrictions across their entire jurisdictions, several authorities are designating zones to target measures to prevent the spread of novel coronavirus where the spread is at its greatest. Maps can quickly indicate not only where COVID is at its worst, but also where restrictions have been put into place. Two examples: New York City (above left) and the province of Quebec (above right). New York’s map is interactive and has an address search, whereas Quebec’s map is spectacularly ungranular: diagonal lines show that a region has more strict restrictions in some areas but not others, but does not map those areas (which are indicated in text).

Last October, Alex Russell released his first pictorial map of a Brooklyn neighbourhood, the Great Map of Greenpoint. It was begun, he says, “as an effort to drive business around the neighborhood. As a restaurant owner in Greenpoint, it was to draw attention to everything this great little area had to offer.” His follow-up, the Great Map of Williamsburg (above), ran straight into the pandemic, as Greenpointers reports:

“My printer closed their doors for a few months just as my order went in,” Russell said of his map, which went to print right as the coronavirus halted New York’s spring. “Sadly, I have recently discovered that a handful of the businesses on The Great Map of Williamsburg have closed due to COVID. I will be delivering their maps to them this week as a bittersweet memory of what was. Some of them, like Brooklyn Charm, had been there for over a decade. I feel honored to have had the chance to be a part of their history.”

Both maps are available for sale as posters; Williamsburg costs $40 and Greenpoint costs $25. [News12 Brooklyn]

On a personal level, the coronavirus map I stare at the most is the one closest to home: a dashboard that shows the regional incidence of COVID-19 in Quebec. Maintained by two geographers at Laval University, it’s extremely helpful in that it shows the per capita rate as well as the raw numbers, which highlights (for example) just how many cases there are in the Eastern Townships, and how few there are here in the Outaouais, as a percentage of the population. [Le Droit]

Less helpful is New York City’s map showing the percentage of patients testing positive for COVID-19, because its neighbourhood detail is so difficult to interpret, as Patch’s Kathleen Culliton points out. “Neighborhoods are designated by numbers instead of name—408 is Jamaica, Queens, by the way—and the percentages are not connected to population data but to those tested. The number of people tested per zone? Not included. The population [per] zone? Not included.” [Kenneth Field]

It’s hard to maintain social distancing in a dense urban environment like New York, but that doesn’t mean that rural areas are inherently safer. Identifying areas that would be hit harder by the coronavirus can be a factor of age and various social vulnerability factors (such as poverty and vehicle access); John Nelson looks at the intersection of age and social vulnerability in this StoryMap and this blog post. The Washington Post’s maps of vulnerability are based on age and flu rates. A third example is Jvion’s COVID Community Vulnerability Map, which is based on anonymized health data from some 30 million Americans [ZDNet].

The New York Times maps the number of cases at the global level and for the United States. It’s also making available county-level coronavirus data assembled from various states and counties, since there seems to be no single agency tracking this at the national level.

Failing to observe social distancing makes the pandemic worse. You might have seeen Tectonix’s video on Twitter, drawn from the location data of mobile devices that were active at a single beach in Florida over spring break, and followed them home. As CTV News reports, the video has drawn fire from privacy advocates, though Tectonix asserts that the data was anonymized and collected with user consent. Meanwhile, the New York Times explores several scenarios of coronavirus spread, comparing what might happen with some control measures, more severe control measures, and no action taken at all.

That 1979 map that has been critiqued, fulminated against and re-imagined over and over again has nonetheless managed to become iconic; however much the map offended various design aesthetics, as the Times obituary (and previous coverage) shows, it was created with care and purpose: the curves were deliberate, the references to aboveground landmarks were deliberate. It was a team effort, but the Times obit had this interesting item about who should get the credit:

There has been some sniping over the years as to who deserves credit for the 1979 map, with Mr. Hertz taking exception whenever Mr. Tauranac¹ was identified as “chief designer” or given some similar title.

“We’ve had parallel careers,” Mr. Hertz told The New York Times in 2012. “I design subway maps, and he claims to design subway maps.”

In 2004, the Long Island newspaper Newsday asked Tom Kelly, then the spokesman for the M.T.A., about who did what.

“The best thing I could probably tell you is to quote my sainted mother: ‘Success has many fathers,’” Mr. Kelly said. “That’s not to disparage any work that anybody else put into the map. But, in all honesty, it’s Mike Hertz that did all the basic design and implementation of it. In all fairness, the father of this map, as far as we’re concerned, is Mike Hertz.”

The 1979 map isn’t quite the same as the current version. Transit Maps posted a copy in 2015, and has this to say about it: “It’s funny how we call this the ‘same’ map as today’s version, because there’s a lot of differences, both big and small. The Beck-style tick marks for local stations as mentioned above, no Staten Island inset, the biggest legend box I’ve ever seen, the colours used for water and parkland … the list goes on!”

The New York Times does a deep dive into New York’s current subway map: its design choices, its history, its quirks. It’s more an animated slideshow than interactive map: each step takes us along a route, bouncing up and down (for example) where you’d expect to walk. It’s also completely devoid of any context, particularly the controversies around this very map’s design. People have been agitated about New York’s subway map, and have been reimagining and rethinking it, for decades.

Yes, I've seen this NY Times subway infographic piece. It's… odd. Seems to excuse bad design with some magical hand waves and expect us to believe this is really the best map that could be made.https://t.co/5xjiAK9EQz

That said, even a naïve look at the status quo isn’t without value, especially since the status quo is rarely looked at on its own terms, but rather in the context of tearing it up and coming up with something new and better.

(Tauranac has been active on this file for a while: he released his own subway map in 2008: it’s a folded map that is geographical on one side and diagrammatic on the other. It seems to be out of print, but I still have a copy in my files.)

And a perusal of my own archives will tell you that the project to reimagine and rethink the New York subway map has been going on a very long time. Last May Jun Seong Ahn posted a rethinking of the subway map—not as the usual poster, but as a wide horizontal map posted above the heads of commuters, as you commonly see in other cities:

Debates about the New York subway map generally involve posters on trains and in stations—flat, paper, static maps. Meanwhile the MTA is moving to digital displays over the next few years, which may afford train and station maps the opportunity to be as dynamic and changing as the maps on riders’ phones. So far, though, the maps are low-resolution and static.

A 1776 map of New York City sold at auction in New York last April for $150,000, the Daily Mail reported at the time. The map is the second edition of the more famous, and rare, 1770 map showing the work of surveyor Bernard Ratzer. It was published in England, and was apparently put to use by British officers during the American Revolution. The New York Public Library’s copy has been digitized and is available online. [WMS]

This seems as good an excuse as any to take a closer look at You Are Here: NYC. Past time, actually, since I’ve had a review copy in my hands for a year now.

You Are Here: NYC is the third of Katharine Harmon’s map books. The first, You Are Here: Personal Geographies and Other Maps of the Imagination, came out in 2003, the second, The Map as Art: Contemporary Artists Explore Cartography, in 2010. Harmon’s distinctive style in editing and curating these books, carries over to the present volume.

First, none of the art is presented bare: Harmon provides one or more full paragraphs providing background and context; like its predecessors, You Are Here: NYC is also peppered with short essays by guest contributors discussing specific pieces in more depth.

Second, Harmon has an expansive view of what constitutes art. There is a great deal of the sort of art that hangs in galleries, but sculptures, textiles and physical installations (represented photographically) are also included. There are also many examples of functional but beautiful maps: not just illustrated works like bird’s-eye maps or pictorial maps, but even geologic maps, maps rendered by computer, and more. Even the Mannahatta Project is included.

And third, Harmon juxtaposes the maps in ways you might not expect: an 1859 map is presented face-to-face with a map from 1967; the maps have nothing to do with one another except that their designs have resonant similarities. These similarities are found across styles of art as well as centuries: nautical charts and fire insurance maps are mixed in with the deliberately artistic and the whimsical.

Fine and good. That Harmon applies her method to maps of a single city may raise eyebrows. Can a single city provide enough material—enough art, enough maps—to fill a volume? Yes, if the city is New York. To map a city like New York is to map a living organism: it comes down to the significance of You Are Here: NYC‘s subtitle (or sub-subtitle): Mapping the Soul of the City. As I wrote in my review of Rebecca Solnit’s Infinite City: A San Francisco Atlas, “Not every city has a soul: some are decidedly soulless. But while I’ve never been to San Francisco, it seems to me that it, at least, is one that does. Cities like that can be magical places: they don’t just have histories, but mythologies, too.” I’ve never been to New York, but I recognize it in Harmon’s pages. I see its pulse, its breath. There are a few other cities in the world that could also generate sufficient artistic and cartographic grist for Harmon’s mill. But not many.

I received a review copy from the publisher’s Canadian distributor.

Inside the lab, conservators talk about the care of antique maps like a doctor discusses a patient’s condition and treatment in an intensive care unit.

Conservators will lay a given map on a table for an exam and diagnose the issue: Is it brittle or burned? Damaged by water or tape? Crumbly, delaminated or peeling? Then they record the treatment in a chart of sorts so that years later, the next caretaker will know what remedy was given.

The repair process of a map—like that for a more than 200-year-old, torn illustration of Williamsburg, Brooklyn—typically takes several hours, though sometimes the conservators will spend days working on just one.

As part of her Project Subway NYC, architect Candy Chan has created a series of X-Ray Area Maps of various New York subway stations. These maps show the subway stations—their platforms, their passages, their staircases—relative to the surrounding streets and buildings. Absolutely engrossing. Chan explains her methodology in this blog post. She’s also selling posters. [Kottke]

Last year I told you about Andrew Lynch’s posters of individual New York subway lines. Now Lynch has created something that will be of interest to anyone who likes the London Underground’s track network map or Franklin Jarrier’s detailed rail maps: a geographically accurate subway track map for New York City, which can be downloaded as a PDF here. He describes how he went about making it (with apologia that sound like standard mapmaking compromises):

Collecting every historical map I could find, using GIS data, satellite imagery (both current and historic), YouTube videos of fan trips, my own observations looking out the window of trains through tunnels, and talking to retired track workers I was able to draw what I believe to be the most accurate track map of the NYC Subway ever. Features I’ve added to the map are all provisions for future expansion and abandoned sections with a notes section explaining each one as well as an exploded view for the more complex stations and areas obscured by overlapping tracks. I’ve elected to remove all streets as not to clutter the map and also not to imply that specific sections (such as crossovers) are perfectly aligned to the street grid. While the map is geographically accurate at this scale tracks had to be spaced far enough apart to read correctly so lines are not perfect aligned with the widths of the streets. Also some train yards have been truncated to fit within the geographical boundaries of the map.

Forbes contributor Tanya Mohn reviews Katherine Harmon’s latest map art book, You Are Here: NYC: Mapping the Soul of the City (previously). If all goes well (it doesn’t always, mind), I should have my own review of this book up later this week. [WMS]

As for the other new map book about New York City, Rebecca Solnit and Joshua Jelly-Schapiro’s Non-Stop Metropolis: A New York City Atlas, there’s a review up on Hyperallergic by Allison Meier, replete with photos of the book. “Every map is an intense act of creative collaboration, with essays and illustrations in Nonstop Metropolis from over 30 artists and writers. […] And the maps emphasize that this city’s character is often missing from our more official cartography.” [WMS]

The Displacement Alert Project Map is a tool built by the Association for Neighborhood and Housing Development that maps, building by building, the risk of gentrification in New York City—i.e., where the rent is about to get too damn high. Intended for use by housing advocates, tenant organizers, community groups and others, the map calculates the risk of displacement—being pushed out of affordable housing—based on several factors. “Access to this data equips communities with information necessary to fight back against the displacement of residents who are being priced out and pushed out of their neighborhoods, to stop the harassment of tenants by bad landlords, and to prevent the expiration and loss and affordable housing units.” [Gothamist/Maps Mania]
