Frederick Pierce’s ‘Dazzle Camouflage’ Map of New York’s Nationalities

Map of City of New York showing the distribution of Principal nationalities by sanitary districts

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.

Where Americans Go without a Car

Map of car-free households in New York CityGeographer Christopher Winters maps car ownership—or rather the lack thereof—in The Geography of Carfree Households in the United States. In only a few census tract do more than 75 percent of the population go without owning a car. Not surprisingly, most of them are in New York, plus other densely populated cities: “New York has many more such households than any other urban area. It’s the one large place in the United States where only a minority of households have a vehicle available.”

Inspired, he says, by Itchy Feet’s maps of Every European City and Every American City, Alfred Twu has come up with a Map of Every Chinese City. (Chinese version here.) Twu is no stranger to these parts: he worked on rail maps for California and the Northeast Corridor some years back.

The Eternal City: A History of Rome in Maps

The Eternal City (cover)Something I often do when reviewing a book is talk about it in terms of the expectations of its potential readers—particularly if readers might come to a book with expectations that the book does not meet, because the book is doing something different. If you’re expecting The Eternal City: A History of Rome in Maps, written by the art historian Jessica Maier and published last November by the University of Chicago Press, to be basically A History of Rome in 100 Maps, it isn’t: the count is more like three dozen. This doesn’t mean that The Eternal City is a slight book—it most certainly is not, though at 199 pages it’s a bit shorter than, say, A History of America in 100 Maps (272 pages).

But counting maps would miss the difference in Maier’s approach. To invoke xkcd, this is depth-first rather than breadth-first: there are fewer maps here, but they’re discussed in much more depth than the two-page spreads of the hundred-map books, and provided with much more context. This is a history of Rome in maps in which history, Rome and maps all get their proper share of attention.

Fire Insurance Maps Online

Penn State University Libraries’ collection of Pennsylvania Sanborn fire insurance maps dates to 1925, which means that as of this year they’re in the public domain—and freely available to use. Meanwhile, Maps Mania has a roundup of other fire insurance maps resources. The Library of Congress has a collection of 50,000 Sanborn atlases, 35,000 of which are available online (collections, navigator). In the United Kingdom, fire insurance maps were produced by Charles E. Goad Ltd.; Goad maps are available via the British Library and the National Library of Scotland.

Fire insurance maps are an invaluable resource for historical researchers: they’re extremely detailed snapshots of the built environment of virtually every city and town, and there are usually several such snapshots (I’ve seen at least three for my little village, for example), so you can chart a town’s growth over time at a level of detail an OS, quad or topo map can’t match.

COVID-19 in Los Angeles

New York Times (screenshot)

The New York Times maps the distribution of COVID-19 cases in Los Angeles. “County officials recently estimated that one in three of Los Angeles County’s roughly 10 million people have been infected with Covid-19 since the beginning of the pandemic. But even amid an uncontrolled outbreak, some Angelenos have faced higher risk than others. County data shows that Pacoima, a predominantly Latino neighborhood that has one of the highest case rates in the nation, has roughly five times the rate of Covid-19 cases as much richer and whiter Santa Monica.”

Critical Tourist Map of Oslo

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:

London Trees, Pyongyang Architecture

Blue Crow Media, which for the past few years has published a series of maps focusing on urban architecture, sent me samples of two of their most recent maps. The Great Trees of London Map is the first of a series of maps highlighting noteworthy trees in a city’s urban forest (Amazon). (A similar map for New York is forthcoming.) The second is another in their line of architecture and urban design maps: Pyongyang Architecture Map features 50 buildings in the reclusive North Korean capital, and includes text and photographs shot by Guardian architecture critic Oliver Wainwright (Amazon). An architecture map of Tbilisi, Georgia, in English and Georgian, has also been released (Amazon). Each map costs £8.

Charles Booth’s London Poverty Maps Online

Last year I told you about Charles Booth’s London Poverty Maps, a book collecting and analyzing the maps produced by Booth’s block-by-block survey of poverty and the social classes of late 19th-century London. Somehow I missed the fact that there has been an online, interactive version of said maps for several years now. [Open Culture]

Underground Cities

Amazon (Canada, UK)
Bookshop

Mark Ovenden has made a career of publishing books about transportation systems and their maps that are both comprehensive and copiously illustrated. These include books about transit maps, railway maps and airline maps, as well as books about specific transit systems like the London Underground and the Paris Metro.

His latest, Underground Cities (Frances Lincoln, 22 Sep), is in some ways a natural progression from his past work: in the introduction he muses on the link between transit geekery and wondering about “what else lies down there beyond the walls” (p. 6). But in other ways this is quite a different book.

COVID-19 in Ottawa Neighbourhoods

Ottawa Public Health has partnered with the Ottawa Neighbourhood Study to produce this interactive map of COVID-19 rates in Ottawa’s neighbourhoods. Both the map and its underlying data are subject to many caveats: the differences between rural and urban zones, between where people live and where people are tested, and other factors affecting testing and susceptibility. Most notably, the map is updated only monthly, so the current map (screenshotted above) does not take into account the rapid increase in positive cases over the past week or two as Ottawa entered the second wave.

Mapping a World of Cities

Map of Tenochtitlan and the Gulf of Mexico, 1524

The Leventhal Center’s latest online map exhibition, Mapping a World of Cities, draws examples of city maps from ten map libraries and collections across the United States; those examples range from a 1524 map of Tenochtitlán (above) to a 1927 map of Chicago gangs.

Looking at maps helps us to understand the changing geography of urban life. Maps didn’t just serve as snapshots of how cities looked at one moment in time; in the form of plans, maps were also used to build, speculate, and fight over urban form. Historical maps reflect cities’ ethnic and economic transformations, systems of domination and oppression, sites of monumentality and squalor. They capture good times and bad, expansion, decay, and destruction. City dwellers take great pride in their cities, as part of a shared sense of place that embedded in a historical trajectory. Maps tell the stories of a city’s past, present—and perhaps its future.

The Library of Congress’s Geography and Map Division contributed five maps to the exhibition; see their post.

Mapping the Monuments of St. Louis

How would you map the monuments of St. Louis?
Monument Lab

In the summer of 2019, a research project spearheaded by Monument Lab asked St. Louis residents and visitors to draw personal maps of the city’s monuments and important sites. “Some maps celebrate famous sites like the St. Louis Zoo and the statue of St. Louis himself atop Art Hill in Forest Park. Others point to things that have been removed from the landscape, like the mounds built by native Mississippians,” St. Louis Public Radio reports. “Another shows a street map of downtown St. Louis with notations for ‘incidents of racism, from microaggression to racial violence.’” A total of 750 people contributed maps, which you can see at this Flickr gallery as well as on the project website, which has accompanying data and analysis.

Building Boston, Shaping Shorelines: A Harvard Map Collection Exhibition

Harvard Library

Building Boston, Shaping Shorelines is a Harvard Map Collection exhibition going on now at Harvard Library’s Pusey Library Gallery. “This exhibition allows you to trace the projects to reclaim land and build the infrastructure that has produced a city out of a peninsula. Come learn how much of Boston is on man-made land and what impacts that has had and will have on the city.” There is no online version, but Harvard Magazine has a writeup. Until 1 May 2020.

A Modern-Day Tube Map in the Original Tube Map Style

Arturs D.

There have been a lot of Beck-style maps—maps done in the style of the London underground map. This one’s a bit meta. Arturs D., a student living in London, has created a map of the present-day London underground using Harry Beck’s original style. The current TfL network map (PDF) is, of course, a Beck-type diagram, but there have been a lot of changes to the official map since 1933. It’s also a lot more complicated. Arturs’s map, which limits itself to the Tube proper, reminds us just how many changes there have been. [Mapping London]
