Restoration work has been completed on the Palazzo Vecchio’s Map Room (no relation); see this Popular Archaeology article for details and photos. In tandem with the restoration, there is now a virtual version of the Map Room that allows you to explore the maps in a virtual facsimile of the room. The maps can also be superimposed on the globe. If this is all a bit too virtual, there’s also an index.

Daylighting Rivers

Last April, CBC News ran an interactive, map-rich story about buried waterways in Canada’s large cities—buried largely for sanitary reasons—and initiatives to restore old and forgotten creeks and rivers to the surface. Focuses on Toronto, Montreal and Vancouver, but there are links to other cities at the end.

A Stranger Quest Now Available Online

A Stranger Quest, the documentary about David Rumsey by Andrea Gatopolous, is now available to the public online, having made its debut last year at the Torino Film Festival (previously) and made the rounds of the film festival circuit. In it, Rumsey, who turned 80 this year, ruminates about loss and mortality, filtered through various lenses: the loss of a friend, the legacy created by a lifetime of map collecting. And let me tell you, it’s a trip. It’s not so much about maps (though the Urbano Monte reconstruction makes several appearances), or map collecting, as it is about a particular map collector; and it approaches its subject edgewise. With long silences, and long scenes shot from enough distance that they make the viewer feel like they’re eavesdropping on private conversations rather than watching a documentary, to say nothing of extended sojourns in Second Life, it’s far from what I would have expected, but I cannot deny the overwhelming art of it.

Reimagining Rural Cartographies

Reimagining Rural Cartographies is a series from independent rural news outlet Barn Raiser that “features written and photo essays that create or examine nontraditional and living maps of the Midwest. How does the path a cougar took to roam into the heart of Chicago help us understand how urban, suburban and rural landscapes are changing? What really happens in the forest at the center of a recent Landback movement? How does the USPS serve as a rural lifeline, connecting neighbors and faraway places, despite service cuts?” Three articles so far.

47 Borders Reviewed

“Someone needs to tell him that the lines on maps are not supposed to be this entertaining.” Drew Gallagher reviews Jonn Elledge’s Brief History of the World in 47 Borders in the Washington Independent Review of Books. “Throughout, Elledge’s writing is equal parts insightful and amusing, and his myriad footnotes contain some of the funniest writing.” (Published too late to make this month’s book roundup.)

A Map of Map Institutions

Andrew Middleton, the owner of the Map Center in Pawtucket, RI (previously), has put together a map of map stores and non-commercial map institutions (archives, libraries, etc.). Comment on Bluesky to suggest other places.

Earlier this month, Andrew posted about the state of the map store, wherein he lays out what makes up his business and where he’d like to go from here. (Mind you, that was before this post and this post went all sorts of viral.)

Did Street View Just Help Solve a Murder Investigation in Spain?

Google Street View (screenshot)

A Street View car passing through the tiny Spanish village of Tajueco captured images of what sure looked like a man loading (or unloading) a wrapped body from the trunk of a car. The images helped authorities solve an outstanding missing person case: remains were discovered earlier this month, and two people have been arrested. News coverage: BBC, El País, New York Times, The Times. Given that it had been 15 years since the last time a Street View car passed through Tajueco, which has maybe 50 inhabitants, doing a shoulder-check for camera-equipped cars was likely not in the forefront of the perpetrators’ minds. (Current screenshot above: the man has since been blurred for obvious reasons.) [Gizmodo, PetaPixel, The Verge]

Book Roundup: December 2024

Volume 7 of the Atlas of Design, opened to a two-page spread showing images of a quilt map by Eleanor Lutz.
Atlas of Design, vol. 7

A lack of time and energy have conspired to prevent me from serving up a gift guide this year, but I can point you to a few links related to books that have come out this year.

First up, I have in my hands a review copy of the seventh volume of the Atlas of Design. It is the usual collection of marvellous cartography from familiar and unfamiliar mapmakers, some of which quite unexpected, and I hope to have more to say about it shortly. It made its debut at the NACIS annual meeting in October and is available to purchase from this page. See my review of the sixth volume.

Matthew Edney’s list of map history books published or seen in 2024 is now live; he’s been posting such a list each year since 2017 (previously).

40 Maps, 47 Borders, 50 Transit Maps

Alaistair Bonnett’s latest, 40 Maps That Will Change How You See the World came out in September from Ivy Press. Geographical magazine published an interview with him in October. I’ve reviewed two of Bonnett’s books here before—Off the Map (Unruly Places) and The Age of Islands (Elsewhere)—which were more about geographical curiosities than maps per se. Amazon (Canada, UK) | Bookshop

To promote A History of the World in 47 Borders (Wildfire, April)—published in the U.S. as A Brief History of the World in 47 Borders (The Experiment, October)—Jonn Elledge has posted a list of the 47 facts about the 47 borders that are the focus of the book’s 47 chapters. Amazon (Canada, UK) | Bookshop

Mark Ovenden’s latest, Iconic Transit Maps (Prestel, 2024) is a look at transit map design via fifty examples around the world. Cameron Booth reviews it on his Transit Maps blog. Way back in 2008, I reviewed the first edition of his Transit Maps of the World. Amazon (Canada, UK) | Bookshop

Book covers for Bonnett’s 40 Maps That Will Change How You See the World, Elledge’s History of the World in 47 Borders, and Ovenden’s Iconic Transit Maps.

Online Exhibition Introduces Cincinnati Library’s Map Holdings

Plan of Cincinnati and Vicinity (1860)
Plan of Cincinnati and Vicinity (S. Augustus Mitchell, 1860). Map, 24×25 cm. CHPL.

How many libraries host map collections that you might be unaware of? The Cincinnati and Hamilton County Public Library’s online exhibition, Landscape and Layers, is an introduction to that library’s map holdings, which per the blog post include 19th- and early 20th-century maps of the city, Sanborn fire insurance maps, and early maps of Ohio.

Jobs Requiring Spatial Memory and Navigation Associated with Low Alzheimer’s Mortality Rates

A population-based study suggesting that people in jobs that require real-time spatial processing—taxi and ambulance drivers—have the lowest rate of Alzheimer’s-related death comes with a bunch of caveats and is reluctant to draw a direct correlation. Per Euronews, people good at spatial processing may be at lower risk regardless of whether they use that skill driving ambulances and taxis. Also:

Independent researchers pointed to a few of those factors, including the fact that the taxi and ambulance drivers in the study died on average around ages 64 to 67, while Alzheimer’s onset is typically after age 65.

Further, few of the drivers were women, who are more likely to develop Alzheimer’s than men, and the analysis didn’t consider genetics or include scans that could show any changes to the brain as a result of their jobs.

So this is a long, long way from being able to say, for example, that driving a taxi prevents Alzheimer’s.

Mapping Every River Reveals a Drop in Water Flow

“Scientists mapped the flow of water through every single river on the planet, every day over the past 35 years, using a combination of satellite data and computer modeling. What they found shocked them,” CNN reports. “Nearly half of the world’s largest downstream rivers—44%—saw a drop in the amount of water flowing through them each year, according to the research published Thursday in the journal Science.” On the other hand, smaller, upstream rivers saw an increase in flow.

The Art and Typography of Sanborn Maps

There are plenty of online resources about Sanborn maps (and other fire insurance maps); Brandon Silverman has built a website focusing on the art and typography found on Sanborn maps’ cover and title pages, with literally thousands of examples.
