Jay Foreman’s look at the history of London’s Tube map is presented as part of his Unfinished London series, rather than as an episode of Map Men, of which he is half, so it’s in a slightly different mode. Slightly. It’s also just the first part.

India Pushing Phone Makers to Adopt NavIC
Reuters reports that the Indian government is pushing mobile phone makers to include support for NavIC, the Indian-government owned satellite navigation system. (At the moment NavIC provides regional coverage from a seven-satellite constellation, but the plan is for 24-satellite global coverage.) Phone makers are resisting the request, citing the additional chips and cost required to support the system. And there’s the matter of redundancy: the current iPhone, for example, already supports BeiDou, Galileo, GLONASS and QZSS in addition to GPS. [9to5Mac]
The Mediterranean’s Summer Heat Wave
Europe’s summer heat wave wasn’t just felt on land; the Mediterranean Sea saw surface temperatures as much as 5°C above the average. The ESA’s animated map, above, shows the difference between sea surface temperatures from March to August 2022 and the 1985-2005 average for those months. The redder, the hotter than average. [ESA]
From Analemma to Zodiac: Bellerby’s Glossary of Globe Terminology
Globemaker Bellerby & Co. has posted a glossary of globe terminology that covers more general geographical terms and concepts (equator, hemisphere) as well as things that are mainly found on globes, covering the various mount types, to common features like time dials and analemmas, to calottes (which are the little circles that cover the poles, where the gore points meet; oddly enough “gore” doesn’t get its own listing).
Audubon’s Bird Migration Explorer
Audubon’s Bird Migration Explorer is the mother of all bird migration maps, with information on the seasonal ranges and migration routes of some 458 bird species in North America.

Wildfire Aware
Wildfire Aware is an interactive map of wildfires in the United States that lists fires by the number of personnel fighting them. Selecting a fire brings up a lot more information, drawn on 22 layers from Esri’s ArcGIS Living Atlas of the World. [ArcGIS Blog]
A New Map for The Wheel of Time
While researching his forthcoming book, Origins of the Wheel of Time (Tor, Nov 2022), Michael Livingston discovered that a map published in a 1997 guide to the Wheel of Time universe—which unlike the maps in the Robert Jordan novels showed the entire world—was, in the opinion of Jordan himself, wrong: according to notes Livingston discovered in the author’s archives, one continent was misnamed and another was too small (see above left). With the permission of the estate, Livingston worked with map artist Ellisa Mitchell—who drew the original map for The Eye of the World—to create a new map of the Wheel of Time world that reflected the author’s intent (see above right). Details, and closeup looks at the maps, at Livingston’s Tor.com article.
Climate Change Could Affect Maritime Boundaries
Sea level rise and coral reef destruction could have an impact on international boundaries, according to a study by University of Sydney researchers published in Environmental Research Letters. Coral reefs form the basis for a number of claims on maritime zones, which could suddenly be in doubt if reef destruction or changes to a reef’s low-water line erase that basis. Press release.
Southeast Asia Historical Maps
The Digital Historical Maps of Singapore and Southeast Asia project, hosted by (the soon-to-be-defunct) Yale-NUS College in Singapore, curates a collection of pre-1900 maps of southeast Asia. The maps are drawn from the Bodleian, Beinecke and Leiden libraries, as well as Singapore’s National Library Board. [Maps Mania]
The Idea of North
Thony Christie explores the question of why north is at the top of modern maps by looking in detail at medieval and early modern maps, which had no consensus. “I think that the re-emergence of the Ptolemaic world map at the beginning of the fifteenth century and the development of modern cartography that it triggered which eventually led to the dominance of north orientation in mapmaking, perhaps combined with the increased use of the magnetic compass.”
Ships Are Increasingly Spoofing Their Location
Ships spoofing their location is an increasing problem, Anatoly Kurmanaev reports for the New York Times. All large ships are required to carry an AIS transponder that transmits the ship’s ID and position, but some ships are starting to find a way around that.
[O]ver the past year, Windward, a large maritime data company that provides research to the United Nations, has uncovered more than 500 cases of ships manipulating their satellite navigation systems to hide their locations. The vessels carry out the deception by adopting a technology that until recently was confined to the world’s most advanced navies. The technology, in essence, replicates the effect of a VPN cellphone app, making a ship appear to be in one place, while physically being elsewhere.
Its use has included Chinese fishing fleets hiding operations in protected waters off South America, tankers concealing stops in Iranian oil ports, and container ships obfuscating journeys in the Middle East. A U.S. intelligence official, who discussed confidential government assessments on the condition of anonymity, said the deception tactic had already been used for weapons and drug smuggling.
We’ve seen examples of this before, but this is starting to look like an endemic problem.
The Gough Map and the Lost Islands of Cardigan Bay
A paper in Atlantic Geoscience is basically arguing that the Gough Map offers evidence that the Welsh legend of the sunken kingdom of Cantre’r Gwaelod —a sort of Welsh Atlantis—is real. Actually, no. Not quite. That’s clickbait—and the headline for the BBC News story about the study.
In their paper, the complete text of which is available online, physical geographer Simon Haslett and professor of Celtic David Willis are trying to reconstruct the post-glacial evolution of Wales’s Cardigan Bay using historical and folklore sources as well as bathymetric data and geological evidence. (It’s pretty obvious which author contributed what.) The Gough Map shows two islands that don’t correlate to any real island in Cardigan Bay; the study suggests that the islands may have in fact existed and have since been lost to flooding, erosion and other post-glacial changes to the shorelines. There are several submarine highs in the bay that may match up with the lost islands. The paper hypothesizes that the Cantre’r Gwaelod legend is a folk memory from when the coast was much different: that there were islands in Cardigan Bay, that they disappeared during the human era, and this legend is one of their traces.
In other words, a bit different from taking an old map at entirely too much face value (which, to be sure, has been enough of a thing that it was first to mind when I saw the story). They’re using the map and the legend to try and figure out the shoreline’s history—not using the map to prove the legend.
McPhee’s Maps of Alberta and Saskatchewan
Alex McPhee’s ridiculously detailed map of Alberta, which included things like the area burned in the 2016 Fort McMurray fire and the province’s Hutterite colonies, came out in print form—specifically, in the form of a 42″×68″ wall map—last year. Now he’s done it again: a similarly detailed 36″×66″ wall map of his home province of Saskatchewan, which he’s just sent to the printer. Each map starts at $60.
