Meander, created by Robert Hodgin, is “a procedural system for generating historical maps of rivers that never existed.” That statement takes some unpacking. It creates maps inspired by Harold Fisk’s 1944 map of the historical path of the Mississippi River with the Houdini 3D animation app. It starts with an input guideline; the river flows and meanders and oxbows from there. Then the system creates land plots that follow the path of the river. And then it creates a road network on top of that. And then it generates names for all these procedurally generated map features. In other words, Meander doesn’t just procedurally generate a river, it generates the entire country it runs through. Whoa.

Using Google Maps to Create a Real-World Paracosm
Brendan Koerner’s 12-year-old son has been spending the lockdown planning a summer road trip in great detail using Google Maps. As it turned out, his son was doing something more than, and other than, simply planning a trip: he was using maps to create a paracosm, one based in data and real locations rather than fantasy space.
In the days that followed, I’d often catch my son on Google Maps with pen in hand, jotting down increasingly specific bits of information that he considered essential to his plans: the names of bridges that span the Susquehanna River, the phone numbers for motor inns in Greater Pawtucket, the best things to eat while watching the New Hampshire Fisher Cats. (The stadium’s clam chowder has received lavish online praise.) As I watched him get lost in the pleasure of these tasks, I realized that he was under no illusions about the trip’s actual odds of taking place. He was immersing himself in Google Maps not because he expected we’d be attending a Norwich Sea Unicorns game anytime soon, but so he could build himself a sanctuary—a space where he’s in charge of how an uncertain future will unfold.
Getting lost in maps is an activity I expect a lot of us recognize, and have done ourselves, though the particulars are probably unique to each of us. (Random thought: Is this one reason why fantasy novels come with maps? Are the maps doing more of the work than we thought?)
Pandemic Mapping and Posterity
The flurry of COVID-19 maps that have emerged in the first half of this year will be something that future cartographers and librarians will look back on, both in terms of historical records that need preserving, which is the subject of this CityLab interview with Library of Congress map librarian John Hessler, and in terms of best practices for disease mapping—what to do and what not to do when mapping a pandemic—which is the subject of this Financial Times video interview with Kenneth Field. (Both from early May; I’m playing catchup right now.)
The Impact of NOAA’s Height Modernization Program
Last month the New York Times covered a subject that you’d expect to be too technical for the general reader: NOAA’s efforts to recalibrate elevation data as part of its update to the National Spatial Reference System, expected in 2022 or 2023. The height modernization program corrects local elevation data—which was last updated in 1988—by using GPS and gravity mapping. The Times article looks at the real-world implications of this effort, which will have the greatest impact the further west and north you go (see map above), from bragging rights about mountain elevation to whether your community is in a floodplain.

Antietam Battlefield Map Shows Burial Locations
A map of the battlefield of Antietam held by the New York Public Library that shows the location of graves of soldiers killed in the 1862 U.S. Civil War battle is the subject of a piece in today’s Washington Post.
Civil War historians are hailing it as an important new way to visualize the toll of the huge battle outside Sharpsburg, Md., in 1862.
“Every one of us who’s looked at this absolutely flips out,” said Garry Adelman, chief historian for the Washington-based American Battlefield Trust, which works to preserve historic battlefields. “This will reverberate for decades.”
The map is the only one of its kind known to exist. It was digitized by the New York Public Library, which owns it, and was spotted online by local historians a few weeks ago.
The map doesn’t just mark graveyards, it notes the burial locations of specific regiments and brigades—and in 45 cases, individual soldiers.
Bending Lines, an Online Exhibition from the Leventhal Center
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.
The Topologist’s Map of the World
Tom created the Topologist’s Map of the World to show how countries connect to each other. Deliberately emulating the style of a T-O map, Tom started with a Voronoi diagram and finished the map in Inkscape. Exclaves are ignored (too complicated), and islands encircle the rest of the map. Among Tom’s observations: “Some countries get really distorted—mostly when they find themselves near the centre of a continent. I’d often thought of Germany as the centre of Europe, but here, Austria and Hungary get really stretched out because they end up bordering countries on opposite sides of the continent.” [r/MapPorn]
Tim Robinson, 1935-2020
Tim Robinson, cartographer and chronicler of the Irish regions of the Aran Islands, the Burren and Connemara, died of complications from COVID-19 on 3 April 2020; he was 85. “Generations of tourists have been guided and enthralled by his marvellous maps of these radiant places,” writes Fintan O’Toole in the Irish Times. “But it is his astonishing books, the two-volume Stones of Aran and the Connemara trilogy, that will stand as timeless monuments to a genius who combined the linguistic brilliance of a poet with the precision of the mathematician he once was.” Also in the Irish Times, Paul Clements looks at Robinson’s idiosyncratic cartography: “For Robinson everything was mappable, and for good measure, he added a few puzzles, doodles and whimsies.”
