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.
Christopher Saxton, Atlas of the Counties of England and Wales, 1579. British Library.
The Yorkshire Society has erected a plaque in Tingley, Leeds, West Yorkshire, to commemorate the 16th-century cartographer Christopher Saxton, the Yorkshire Evening Post reports. Saxton produced the first county maps of England and Wales; they were collected in his 1579 Atlas of the Counties of England and Wales. A major name in the history of British cartography (see this page about Saxton from the University of Glasgow Library), Saxton was born in West Yorkshire—thus the local interest. [WMS]
Elevation change of Mount Rainier glaciers, 1970-2016. David Shean/University of Washington.
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. Start here and scroll down.

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 bookmart@psl.bm, 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.”
“Bird’s-eye View of the Eastern Railroad Line to the White Mountains and Mt. Desert.” Boston: Rand Avery Supply Co., 1890. Harvard University Library.
Opening today at Harvard University in front of the Map Collection in Pusey Library and running until 28 February, Look but Don’t Touch: Tactile Illusions on Maps looks at the use of simulated textures in maps.
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).

This seems as good an excuse as any to take a closer look at You Are Here: NYC. Past time, actually, since I’ve had a review copy in my hands for a year now.
Geographical magazine reviewsThe Red Atlas, the survey of Soviet-era topo maps of the world by John Davies and Alexander J. Kent out this month from University of Chicago Press. National Geographic’s All Over the Map blog also has a feature on The Red Atlas. I’ve received my own review copy of The Red Atlas and hope to have a review for you … at some point (I’m rather backlogged).
Audubon Alaska, Ecological Atlas of the Bering, Chukchi, and Beaufort Seas.
Audobon Alaska’s Ecological Atlas of the Bering, Chukchi, and Beaufort Seas maps the environment, biota and wildlife in the three seas surrounding the Bering Strait, as well as the human activity that puts them at risk. The cartography is by Daniel Huffman and not by coincidence excellent. It’s available for download as PDF files, either chapter-by-chapter or a whopping 125-megabyte single download; a print copy costs $125 with shipping and handling. [NACIS]
