The Berlin Wall Fell 30 Years Ago. Where Did It Go?
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.
Pretty heavy web page.

Philadelphia Slaughterhouse Hotel
> Yesterday on my other blog I posted about the most hilariously mislocated hotel I’ve ever heard of. It’s the hotel that in 1910 was located in the Philadelphia stockyards, just the other side of the railroad tracks from the hog pens, between the slaughter house and the abbatoir:
Urbano Monte’s Massive Map of the Earth (1587)
> In 1587, Urbano Monte made the largest known early map of Earth. The map consists of 60 panels that were meant to be assembled into a planisphere (a circular map that rotates about a central axis) measuring 10 feet across. The David Rumsey Map Center recently acquired a manuscript of Monte’s map and digitally assembled all 60 pieces into the full map (inlined above but click through to zoom/pan).
The Marvelous Mississippi River Meander Maps
> Fisk’s maps represent the memory of a mighty river, with thousands of years of course changes compressed into a single image by a clever mapmaker with an artistic eye. Looking at them, you’re invited to imagine the Mississippi as it was during the European exploration of the Americas in the 1500s, during the Cahokia civilization in the 1200s (when this city’s population matched London’s), when the first humans came upon the river more than 12,000 years ago, and even back to before humans, when mammoths, camels, dire wolves, and giant beavers roamed the land and gazed upon the river.
This map shows the most commonly spoken language in every US state, excluding English and Spanish
> English is, unsurprisingly, the most commonly spoken language across the US, and Spanish is second most common in 46 states and the District of Columbia. So we excluded those two languages in the above map.
Here Grows New York
> Here Grows New York visually animates the development of this city’s street grid and infrastructure systems from 1609 to the present day, using geo-referenced road network data, historic maps, and geological surveys. The resulting short film presents a series of “cartographic snapshots” of the built-up area at intervals of every 20-30 years in the city’s history. This process highlights the organic spurts of growth and movement that typify New York’s and most cities’ development through time. The result is an abstract representation of urbanism.
Medieval Fantasy City Generator
> This application generates a random medieval city layout of a requested size. The generation method is rather arbitrary, the goal is to produce a nice looking map, not an accurate model of a city. Maybe in the future I’ll use its code as a basis for some game or maybe not.
Chicago Parking Ticket Visualization
> In this post, I want to show off a fun little web app I made for visualizing parking tickets in Chicago, but because I’ve spent so much time on the overall project, I figured I’d share the story that got me to this point. In many ways, this work is the foundation for my interest in public records and transparency, so it has a very special place in my heart.

Drift of the North Pole forces early magnetic map update
> As the magnetic field’s quirks are dynamic, the model has to be updated, which is done on a five-year schedule. The rate of the North Pole’s motion, however, has been fast enough that the agencies who produce the model aren’t comfortable with waiting for the current model expiration at the end of 2019.
The 26,000-Year Astronomical Monument Hidden in Plain Sight
> On the western flank of the Hoover Dam stands a little-understood monument, commissioned by the US Bureau of Reclamation when construction of the dam began in 01931. The most noticeable parts of this corner of the dam, now known as Monument Plaza, are the massive winged bronze sculptures and central flagpole which are often photographed by visitors. The most amazing feature of this plaza, however, is under their feet as they take those pictures.
> The plaza’s terrazzo floor is actually a celestial map that marks the time of the dam’s creation based on the 25,772-year axial precession of the earth.
