New Leventhal Exhibition: Processing Place

Published on by Jonathan Crowe

An exhibition exploring the history of computerized mapping, GIS and remote sensing opened at the Boston Public Library’s Leventhal Map Center last Friday. Processing Place: How Computers and Cartographers Redrew our World runs until March 2025.

In the long history of mapmaking, computers are a relatively new development. In some ways, computers have fundamentally changed how cartographers create, interpret, and share spatial data; in others, they simply mark a new chapter in how people have always processed the world. This exhibition features objects from the Leventhal Center’s unique collections in the history of digital mapping to explore how computers and cartographers changed one another, particularly since the 1960s. By comparing maps made with computers to those made before and without them, the exhibition invites us to recognize the impacts of digital mapping for environmental management, law and policy, navigation, national defense, social change, and much more. Visitors will be encouraged to consider how their own understanding of geography might be translated into the encodings and digital representations that are essential to processing place with a computer.

The online version of the exhibition is here.

New Leventhal Exhibition: ‘Heaven and Earth: The Blue Maps of China’

A new exhibition at the Boston Public Library’s Leventhal Map Center, Heaven and Earth: The Blue Maps of China, focuses on two extraordinary Chinese maps from the early 19th century printed using Prussian blue pigment.

These maps were presented in an extraordinary format, on eight vertical sheets printed in the style of rubbings. Even more strikingly, they were rendered in a rich blue coloring. The pigment Prussian blue had recently begun to be produced in China, and these maps were amongst the first printed objects in East Asia to make use of the colorant—predating the famous use of Prussian blue by Japanese print artists soon after.

The blue maps were more than just visually astonishing. They also captured Chinese ideas about the relationship between terrestrial and celestial space, and still provide insight today into how Chinese scholars and artists conceptualized the world around them. Beautiful and powerful in equal measure, these blue maps capture details of a transitional moment in the history of China—and the wider world. This exhibition considers these two maps in the context of their production, consumption, and functionality, revealing them as unique objects in the global history of mapmaking.

The online version is full of interesting detail about the maps’ materials and production. The physical exhibition opened last weekend and runs until 31 August 2024. Free admission.

Speaking of georeferencing old maps, the Leventhal Map Center at Boston Public Library has a collection of late 19th- and early 20th-century urban atlases. Their Atlascope platform presents 101 of them in a web interface overlaid on a modern street map. The Leventhal is now looking to expand Atlascope’s coverage beyond the Boston area to towns and counties across Massachusetts, and is raising funds to do so (it can apparently take 60 hours to process one atlas). Details on sponsoring an atlas here. See their Instagram post.

Poems on Maps

Published on by Jonathan Crowe

The Leventhal Map Center looks at poems on maps. Not about maps, on maps. “It just so happens that many of the maps in our collection have poems inscribed on them, in legends, around borders, and hidden away in overlooked corners. We find them primarily on pictorial maps, and the poems are mainly by men from the 20th century literary canon, but the maps they are on cover a wide geographic range.”

Georeferencing Familiar Places

Published on by Jonathan Crowe

On the Leventhal Map Center’s website, Ezra Acevedo describes what it’s like to georeference a century-old atlas of your hometown. “Spending many hours poring over maps of such a well known place was really exciting. My knowledge of the town coupled with its resistance to change meant that the historic maps of Ipswich weren’t all that difficult to line up with the modern map. However, I did learn four important lessons while georeferencing my hometown.”

New Leventhal Exhibition: More or Less in Common

Published on by Jonathan Crowe

More or Less in Common: Environment and Justice in the Human Landscape is the latest exhibition at the Boston Public Library’s Leventhal Map and Education Center.

In More or Less in Common: Environment and Justice in the Human Landscape, we take a look at how questions of social justice and injustice are essential topics to confront when trying to understand the human landscape. These questions must also be at the center of our attention as we challenge ourselves to build better, healthier environments in the future. Through maps as well as photographs, images, and data visualizations, this exhibition encourages you to confront stories about how environmental conditions have sometimes served to worsen inequalities along lines of social division. At the same time, our shared environment offers the possibility to bring people together across differences and the inspiration to forge new kinds of common action.

This is a hybrid physical/digital exhibition that can be visited in person or viewed online. It opened on March 18 and runs until December 28. See the Boston Globe’s coverage.

Mapping a World of Cities

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.

Bending Lines, an Online Exhibition from the Leventhal Center

Published on by Jonathan Crowe

Bending Lines: Maps and Data From Distortion to Deception, the latest exhibition from the Leventhal Map and Education Center at the Boston Public Library, is a wide-ranging, comprehensive look at the relationship between maps and the truth. We expect maps not to lie, but maps have misled, propagandized or at the very least provided a particular perspective for as long as there have been maps.

Every map is a representation of reality, and every representation, no matter how accurate and honest, involves simplification, symbolization, and selective attention. Even when a map isn’t actively trying to deceive its readers, it still must reduce the complexity of the real world, emphasizing some features and hiding others. Compressing the round globe onto a flat sheet of paper, and converting places, people, and statistics into symbols, lines, and colors is a process inherently fraught with distortion. […]

In Bending Lines: Maps and Data From Distortion to Deception, we explore the many ways in which maps have “bent” reality and created a picture of the world that is oftentimes more real than reality itself. Some of the maps in this exhibition are deliberately nefarious, created by people or institutions who are trying to mislead or persuade. But for many of the others, the relationship between map and truth is more ambiguous. Some maps dim a certain type of truth in order to let another type of interpretation shine through, while others classify and categorize the world in ways that should raise our skepticism. And for some of the maps shown here, the persuasive goal isn’t trickery but liberation, as they seek to raise awareness of truths that were previously obscured or oppressed.

This exhibition was to have launched last month, but thanks to the pandemic has had to go fully online. Tackling everything from persuasive cartography to map projections to the sort of thing Mark Monmonier talks about in How to Lie with Maps, it’s an enormous undertaking in more than one sense. CityLab’s Laura Biss interviews the Leventhal’s curator, Garrett Dash Nelson, about the exhibition.

Update, 2 July: Harvard Magazine looks at the exhibition.

New Leventhal Exhibition: America Transformed

Published on by Jonathan Crowe

The Leventhal Map Center’s latest exhibition, America Transformed: Mapping the 19th Century, opened last Saturday and runs until 10 November 2019.

During the 19th century, the United States expanded dramatically westward. Immigrant settlers rapidly spread across the continent and transformed it, often through violent or deceptive means, from ancestral Native lands and borderlands teeming with diverse communities to landscapes that fueled the rise of industrialized cities. Historical maps, images and related objects tell the story of the sweeping changes made to the physical, cultural, and political landscape. Moving beyond the mythologized American frontier, this map exhibition explores the complexity of factors that shaped our country over the century.

As usual, there’s a comprehensive online version, which is peppered with acknowledgements of the very white, very settler-colonialist perspective of the maps on display. Which are, of course, justified, but as far as I can see they’re asterisks and asides on an otherwise unchanged exhibit.

New Exhibition at the Leventhal: Crossing Boundaries

Published on by Jonathan Crowe

A new exhibition opened at the Leventhal Map Center today: Crossing Boundaries: Art // Maps “juxtaposes contemporary works of art with selected maps from the collections of the Norman B. Leventhal Map and Education Center at the Boston Public Library. These pairings and trios create dialogues that illuminate the crossing of the traditional boundaries of art and maps, and stimulate a fresh appreciation of both media.” Runs until 20 April 2019; if you can’t make it to Boston there’s an online version.

Update, 24 October: Here’s a writeup from the Boston Globe.

Breathing Room: Mapping Boston’s Green Spaces

Breathing Room: Mapping Boston’s Green Spaces is the latest exhibition put on by the Leventhal Map Center at the Boston Public Library.

Boston boasts some of the nation’s most recognizable and cherished green spaces, from Boston Common, to the Emerald Necklace, to hundreds of neighborhood parks, playgrounds, tot lots, community gardens, playing fields, cemeteries, and urban wilds. In this exhibition, you will learn how the country’s oldest public park grew from a grazing pasture to an iconic recreational and social center, how 19th-century reformers came to view parks as environmental remedies for ill health, how innovative landscape architects fashioned green oases in the midst of a booming metropolis, and what the future holds for Boston’s open spaces. As you explore three centuries of open space in Boston, perhaps you will feel inspired to go outside and discover the green spaces in your own backyard.

The online version is here. It opened last Saturday and runs until 23 September; for some reason the opening ceremony isn’t until April 3rd.

Map Exhibitions in Boston

Published on by Jonathan Crowe

“Bird’s-eye View of the Eastern Railroad Line to the White Mountains and Mt. Desert.” Boston: Rand Avery Supply Co., 1890. Harvard University Library.

Opening today at Harvard University in front of the Map Collection in Pusey Library and running until 28 February, Look but Don’t Touch: Tactile Illusions on Maps looks at the use of simulated textures in maps.

Beginning particularly in the eighteenth century, philosophers began to debate what role each of our senses has in this experience. For eighteenth-century philosophers, the crucial distinction was between sight and touch. Would we, they asked, be able to experience depth and understand size without our sense of touch? George Berkeley and Etienne Bonnot, Abbé de Condillac, among others, hypothesized that touch, in fact, was primarily responsible for our experience and understanding of space. All visual knowledge about depth and size, they suggested, derived from tactile experiences. In other words, we needed touch to teach us to see. But what happens to the map if we take seriously this challenge to a visual understanding of space?

All maps in this exhibition toy with the relationship between touch and sight. For some, their interest in touch and sight is ornamental. Either by delighting in the visual illusion of tactility or by referring to a visual cliché, these maps enliven their design—and attract buyers—by appealing to our hands. For others, their interest in touch and sight is about knowledge itself. Either by depicting cartographers’ tools and materials or by tempting us to touch what is not there, these maps play with our sense of what a map is and where it comes from. Paradoxically, they teach us visually about particular places while also questioning the basis for their own visual instruction.

The online version can be found here.

Meanwhile, the Boston Globe has a review of the Leventhal’s exhibition on subsurface mapping, Beneath Our Feet: Mapping the World Below (previously).
