The map is bad, is my point, and obviously bad, and I sincerely wish that we didn’t have to talk about it. But we do. Because maps like this one aren’t merely birdbrained schlock: They are a social media plague, a scourge that can reduce just about any social network to gibbering in-fights in the space of a few virally shared minutes. We’re all susceptible; we’re all defenseless. A dumb internet map with incendiary falsehoods is coming for all of us, and there is just about nothing we can do to stop it.
The formula goes something like this: Map plus declaration of definitive statewide preference equals profit. Profit here means eyeballs or clicks or reshares or, most likely, some combination of all three, especially the last one, because it turns out that there are few sentiments more appealing than Oy, check out the terrible things the cretins in [Bad State] get up to.
The truth is we’re all very boring, and our preferences aren’t all that different.

The problem is that even though their methodologies are shoddy and their conclusions are dubious, clickbaity maps like these are popular. The competition for attention is fierce, and maps are a quick and dirty way of generating traffic. My traffic skyrockets whenever I post a link to something even remotely like these maps (xkcd is usually a safe bet), and if I resorted to posting maps like these all the time, I’d be making muchmore money at this. But I wouldn’t be able to look myself in the mirror.
An artifact recovered in 2014 from the wreck of one of Vasco da Gama’s exploring ships, the Esmerelda, which sank in the Indian Ocean 1503, was believed to be an astrolabe, a navigation tool used to measure the inclination of celestial objects, but the 17.5-cm bronze disc appeared to lack any navigational markings. Scanning and 3D imaging the object at the University of Warwick revealed etches separated by five degrees along the edge, confirming that it was, in fact, an astrolabe. It’s dated to between 1495 and 1500, roughly, which makes it the oldest known astrolabe still in existence. BBC News. [Tony Campbell]
It’s in French, and the accompanying text is weighted toward Quebec examples, but Le Devoir’s interactive map showing neighbourhood-by-neighbourhood median income levels, based on recent census data, and how they relate to the national average is worth looking at even so. [Nathaniel Kelso]
There are many circumstances where the amount of data vastly exceeds the ability to process and analyze it—and computers can only do so much. Enter crowdsourcing. Steve Coast points to Digital Globe’s Tomnod project, which basically crowdsources satellite image analysis. In the case of the current project to map the presence of Weddell seals on the Antarctic Peninsula and the ice floes of the Weddell Sea, users are given an image tile and asked to indicate whether there are seals in the image. It’s harder than it looks, but it’s the kind of routine task that most people can do—many hands, light work and all that—and it helps researchers focus their attention where it needs focusing. (A similar campaign for the Ross Sea took place in 2016.)
Another ongoing campaign asks users to identify flooded and damaged infrastructure and trash heaps in post-Hurricane Maria Puerto Rico.
Using elevation data from stereo satellite observations, David Shean is mapping the retreat of some 1,200 mountain glaciers in the continental United States. “Until recently, glaciers in the United States have been measured in two ways: placing stakes in the snow, as federal scientists have done each year since 1957 at South Cascade Glacier in Washington state; or tracking glacier area using photographs from airplanes and satellites.” Shean’s method, which measures each glacier twice a year and uses automated software to track changes, seems to cover a lot more territory.

Excellent Twitter thread from Jeannette Ng talking about old maps in the context of fantasy map design. It’s a subject near and dear to my heart: fantasy maps are essentially modern maps whose design language post-dates 16th- or 17th-century mapmakers like Olaus Magnus and Joan Blaeu; Ng talks about what are essentially the non-geographic purposes of old maps, and as I understand things she is entirely correct.

Atlas of Nebraska by J. Clark Archer et al. (Bison Books). “Far more than simply the geography of Nebraska, this atlas explores a myriad of subjects from Native Americans to settlement patterns, agricultural ventures to employment, and voting records to crime rates.” [Amazon]
Update (30 Oct.): Jonathan Land Evans writes with information on overseas orders for his book, Bermuda Maps: “The most direct way by which people overseas may order copies is by e-mailing firstname.lastname@example.org, as the museum now uses The Bookmart bookstore in Bermuda for all order-fulfillment involving shipping to addresses outside Bermuda. The hardback book is a large one, handsomely illustrated in colour, and costs $65 plus postage.”
Beginning particularly in the eighteenth century, philosophers began to debate what role each of our senses has in this experience. For eighteenth-century philosophers, the crucial distinction was between sight and touch. Would we, they asked, be able to experience depth and understand size without our sense of touch? George Berkeley and Etienne Bonnot, Abbé de Condillac, among others, hypothesized that touch, in fact, was primarily responsible for our experience and understanding of space. All visual knowledge about depth and size, they suggested, derived from tactile experiences. In other words, we needed touch to teach us to see. But what happens to the map if we take seriously this challenge to a visual understanding of space?
All maps in this exhibition toy with the relationship between touch and sight. For some, their interest in touch and sight is ornamental. Either by delighting in the visual illusion of tactility or by referring to a visual cliché, these maps enliven their design—and attract buyers—by appealing to our hands. For others, their interest in touch and sight is about knowledge itself. Either by depicting cartographers’ tools and materials or by tempting us to touch what is not there, these maps play with our sense of what a map is and where it comes from. Paradoxically, they teach us visually about particular places while also questioning the basis for their own visual instruction.
This NOAA article looks at three kinds of imagery provided by the GOES-16 geostationary weather satellite: GeoColor, the Geostationary Lightning Mapper (!), and full disk infrared imagery from the Advanced Baseline Imager. GOES-16 launched last November and is currently in the checkout phase before it replaces GOES-13 at 75° west latitude.
On 1 September Michelin announced that it had acquired the assets previously held by Streetwise Maps, in an all-cash deal. Streetwise announced that it was closing last year. Michelin will continue to publish maps under the Streetwise name; their publishing wing already produces a ton of travel guides, restaurant guides and maps (my Michelin map of Paris was essential during my trip there).
