Laura Bliss and Carlyn Osborn continue their series of blog posts on women in cartographic history at CityLab and Worlds Revealed, respectively. Bliss looks at 20th century women, including illustrators Louise E. Jefferson and Ruth Belew as well as seafloor mapper Marie Tharp; Osborn looks at Dutch mapmaker Anna van Westerstee Beek (1657–1717).
CityLab’s Laura Bliss has a second post on women and cartography, this time focusing on the work of 19th-century women cartographers, geographers and educators in the United States. The Library of Congress’s map blog, Worlds Revealed, focuses on the work (and maps) of one of those women, Emma Hart Willard.
Cameron Booth’s latest project is a New York subway map in the form of the London Tube Map: “A little while ago, someone asked me on my Transit Maps blog whether I had ever seen a map of the New York subway system in the style of the London Underground diagram. Rather surprisingly, I hadn’t actually come across one, so I decided to draw one up myself.”
I’m surprised someone hasn’t done one already, but then there’s the problem of service pattern complexity unique to New York, which Cam handles by simply not handling it—making this a design exercise rather than a usable map. “The map certainly looks attractive, but the Tube Map’s style is ill-suited to the intricate working complexities of the New York subway system.”

Three years ago, the Newberry Library posted a note about a 1922 cartoon from the Chicago Tribune: “The New Yorker’s Idea of the Map of the United States” by John T. McCutcheon bears a strong resemblance to Saul Steinberg’s famous 29 March 1976 New Yorker cover, whose inspiration is often traced to Daniel K. Wallingford’s A New Yorker’s Idea of the United States (1937). See the gallery below.
Bland’s career predated Forbes Smiley’s (he lacked Smiley’s ostensible pedigree) and was the focus of Miles Harvey’s 2000 book The Island of Lost Maps: A True Story of Cartographic Crime (Amazon, iBooks).
Smiley was, of course, the subject of Michael Blanding’s 2014 book The Map Thief (Amazon, iBooks; see my review). Blanding is on a bit of a campus speaking tour at the moment, discussing the Smiley case. He’s at the University of Florida tonight, the University of Miami tomorrow night, and more college campuses in April and May.
A new gravity map of Mars, based on data from three orbiting spacecraft, has been released. “Slight differences in Mars’ gravity changed the trajectory of the NASA spacecraft orbiting the planet, which altered the signal being sent from the spacecraft to the Deep Space Network. These small fluctuations in the orbital data were used to build a map of the Martian gravity field.”
The data enables the crustal thickness of Mars to be determined to a resolution of approximately 120 kilometres. Here’s a short video explaining the significance:
On the Library of Congress’s map blog, a post about the women cartographers employed by the military and government during World War II—the so-called “Military Mapping Maidens.”
The Guardian has a brief item on ocean mapper Marie Tharp.
CityLab’s Laura Bliss presents a selection of maps by women mapmakers like Mary Ann Roque, the Haussard sisters and Shanawdithit, the last known member of the Beothuk people.

Point Google Maps or OpenStreetMap at a city like Dar es Salaam, Tanzania and you’ll get a reasonably good map. What you won’t get is Street View or street-level imagery—or, necessarily, the data that comes from a street-level understanding of the territory. NPR’s Nadia Whitehead looks at a joint project of the World Bank and Mapillary, a company that crowdsources street-level photos, to produce those images. “Volunteers are mounting camera rigs to their tuk tuks—three-wheeled motor-powered vehicles—to snap pictures as they cruise Dar es Salaam’s dirt roads. Others download the Mapillary app on their smartphones and capture images as they walk or hitch rides on motorbikes. In all, more than 260 people have volunteered.” [via]
The Electric Map of the Battle of Gettysburg, once a mainstay of Gettysburg National Military Park, closed in 2008; in 2012 it was purchased at auction for $14,000 by Scott Roland, a businessman who planned to reopen it as a tourist attraction in downtown Hanover, Pennsylvania, about 16 miles east of Gettysburg. Renovating and reassembling the map has taken Roland longer than he originally expected, the Evening Sun reports, but he believes the map will be ready by the end of the school year. [via]
A copy of an 1853 map of Texas by Jacob de Cordova found in a $10 box of ragtime sheet music sold at auction last weekend for $10,000. The map, once owned by surveyor James M. Manning, who died in 1872, was bought, along with a related letter, by Texas A&M University—Corpus Christi, whose library houses the Manning papers. [via]
The New York Times maps the impact of Russian airstrikes on the Syrian civil war. Using several maps to indicate the impact on each faction—government, rebels, ISIS and Kurds—strikes me as quite effective, as is the use of colour-highlighted text in the headings, rather than a legend, to indicate each faction.
Also in Lisbon, also in June: the third symposium of the International Society for the History of the Map. Its theme: Encounters and Translations: Mapping and Writing the Waters of the World. It takes place 3-4 June 2016 at the National Library of Portugal in Lisbon—just before the portolan chart workshop. [via]
In the 48 hours since I posted on how to support The Map Room, 18 readers have contributed a total of $166. That’s tremendous given the size of my audience: there may not be many of you, but you’re hardcore. The split between buying me a coffee (it’s a tip jar, actually) and contributing to my web hosting was 28:72. Contributions to the latter are sufficient to pay for 10 months of web hosting on my current plan; they’d take a big bite out of the additional cost of the upgraded plan, which I will now look into. I deeply appreciate the support. Thank you.
