Projection Connections: A Very Nerdy Poster
Friends, I’m excited to offer to you a new poster. Not a map this time around, but something map-related. A 16 × 24-inch tangled web showing how 100+ different map projections are all related to each other.
Washington is a city of great bridges and terrible bridges. These are their stories.
An Orbit Map of the Solar System
This map shows the orbits of more than 18000 asteroids in the solar system. This includes everything we know of that’s over 10km in diameter - about 10000 asteroids - as well as 8000 randomized objects of unknown size. Each asteroid is shown at its position on New Years’ Eve 1999, colored by type of asteroid.
Geeking out over arbitrary boundaries
Reddit today had this delightful map, I think drawn by PeterVexillographer, of “the largest city in each 10-by-10 degree area of latitude-longitude in the world”:
Some commentary on the near misses.
The U.S. Is Getting Shorter, as Mapmakers Race to Keep Up
Scientists are hard at work recalibrating where and how the nation physically sits on the planet. It’s not shrinkage — it’s “height modernization.”
The grand recalibration, called “height modernization,” is part of a broader effort within the National Oceanic and Atmospheric Administration, or NOAA, to establish more accurately where and how the United States physically sits on the planet. This new National Spatial Reference System, encompassing height, latitude, longitude and time, is expected to be rolled out in late 2022 or 2023, Ms. Blackwell said. It will replace reference systems from the 1980s that are slightly askew, having been derived from calculations that were done before the advent of supercomputers or global navigation satellite systems such as GPS.
Coronavirus Mutations Map the Global Outbreak
For the first time during a global outbreak, scientists have been able to use genomic data in real time to track how a virus is traveling around the world, revealing sources of outbreaks and shedding light on cases with unknown origins.
By identifying mutations in the genetic sequence of samples of the coronavirus, which are markers for various strains, researchers have offered clues to whether some cases came from a local source or elsewhere in the world.
Escape Into These Fantastical, Imaginary Maps
This week, why not venture even farther afield, to lands that don’t really exist at all? Atlas Obscura recently asked map collectors and curators to suggest some diverting maps that chart imaginary terrain.
David Rumsey Historical Map Collection
The David Rumsey Map Collection was started over 30 years ago and contains more than 150,000 maps. The collection focuses on rare 16th through 21st century maps of North and South America, as well as maps of the World, Asia, Africa, Europe, and Oceania. The collection includes atlases, wall maps, globes, school geographies, pocket maps, books of exploration, maritime charts, and a variety of cartographic materials including pocket, wall, children’s, and manuscript maps. Items range in date from about 1550 to the present.
This is fantastic.

George III's collection of military maps
George III’s collection of military maps comprises some 3,000 maps, views and prints ranging from the disposition of Charles V’s armies at Vienna in 1532 to the Battle of Waterloo (1815).
Most notable among these are the military maps, prints and drawings collected by his uncle, William Augustus, Duke of Cumberland (1721–65), particularly during his period as Captain General of the British army during the War of the Austrian Succession (1743–8) and the Seven Years War (1756–63).
The second major collection, bought by George III in 1763, was that of the military prints collected by the Italian art patron, Cassiano dal Pozzo (1588–1657). In addition to these, George III acquired hundreds of maps of contemporary conflicts, such as the American War of Independence (1775–83), and the French and Napoleonic Wars (1792–1815).

History of Cartography
The first volume of the History of Cartography was published in 1987 and the three books that constitute Volume Two appeared over the following eleven years. In 1987 the worldwide web did not exist, and since 1998 book publishing has gone through a revolution in the production and dissemination of work. Although the large format and high quality image reproduction of the printed books (see right column) are still well-suited to the requirements for the publishing of maps, the online availability of material is a boon to scholars and map enthusiasts.
On this site the University of Chicago Press is pleased to present the first three volumes of the History of Cartography in PDF format.

The Commuting Principle That Shaped Urban History
In 1994, Cesare Marchetti, an Italian physicist, described an idea that has come to be known as the Marchetti Constant. In general, he declared, people have always been willing to commute for about a half-hour, one way, from their homes each day. This principle has profound implications for urban life. The value of land is governed by its accessibility—which is to say, by the reasonable speed of transport to reach it.
But the endurance of the Marchetti Constant has profound implications for urban life. It means that the average speed of our transportation technologies does more than anything to shape the physical structure of our cities. To see how, let’s travel back in time by more than 2,000 years, and move towards the present.
What is Haberman?
I’d never heard of “Haberman” before. The name of the neighborhood that people who live here would recognize is Maspeth (which you can see up-and-to-the-right of Haberman). Is Haberman even a real neighborhood? Why did Google put this giant Haberman label on the map?
The scramble to secure America’s voting machines
Paperless voting devices are a gaping weakness in the patchwork U.S. election system, security experts say. But among these 14 states and their counties, efforts to replace these machines are slow and uneven, a POLITICO survey reveals.
Very annoying scroll interaction at the top, but eventually some content appears.
The Atlas of Moons
Our solar system collectively hosts nearly 200 known moons, some of which are vibrant worlds in their own right. Take a tour of the major moons in our celestial menagerie, including those that are among the most mystifying—or scientifically intriguing—places in our local neighborhood.
