The London Medieval Murder Map

A project of Cambridge’s Violence Research Centre, the London Medieval Murder Map is an interactive map that plots 142 murders from the first half of the 14th century onto one of two maps of London: a 1572 map from Braun and Hogenberg’s Civitates Orbis Terrarum or a map of London circa 1270 published by the Historic Towns Trust in 1989. The interactive map is powered by Google Maps, but the Braun and Hogenberg is not georectified, so the pushpins shift as you toggle between the base maps. [Ars Technica]

Giant 1940 Model of San Francisco Digitally Assembled

WPA model of San Francisco (David Rumsey Map Collection)

A massive wooden model of the city of San Francisco that has not been on display, at least in one piece, since 1942 has been re-assembled as a virtual model by the David Rumsey Map Collection. Built by the WPA, the model was assembled from 158 individual pieces to form a massive, 42×38-foot (12.8×11.6m) model at a scale of 1:1,200, and represented a snapshot of the city as it was in 1940. It’s available as a single composite image, as well as images of individual pieces; a Google Earth layer enables the model to be viewed at an oblique angle and superimposed on modern satellite imagery. Sections of the model itself will be on display at various branches of the San Francisco Public Library as part of Bik Van der Pol’s Take Part project; the exhibits will take place between 25 January and 25 March 2019.

A Tube Map of Earthsea

A Tube Map of Earthsea (Camestros Felapton)

Everything under the sun can be expressed as a Tube map. Including, as blogger Camestros Felapton demonstrates above, Ursula K. Le Guin’s Earthsea books. A glance at the original and official maps of Earthsea reveals that world as an intricate, almost overwhelming archipelago: Camestros’s map, like all good transit diagrams, expresses the books as journeys between points.

World Magnetic Model Being Updated a Year Early

The World Magnetic Model—the standard model of the Earth’s magnetic field and a crucial part of modern navigation systems—was last updated in 2015. That update was supposed to last until 2020, but problems with the model started within a year of the last update. As Nature reports, a geomagnetic pulse under South America in 2016 made the magnetic field “lurch”:

By early 2018, the World Magnetic Model was in trouble. Researchers from NOAA and the British Geological Survey in Edinburgh had been doing their annual check of how well the model was capturing all the variations in Earth’s magnetic field. They realized that it was so inaccurate that it was about to exceed the acceptable limit for navigational errors.

As a result, the WMM is being updated a year early—this month, in fact, though the U.S. government shutdown is pushing back the release of the updated model.

Stanfords Cartographer: ‘Paper Is Going to Make a Comeback’

You know who isn’t worried about the future of paper maps and whether people still know how to use them? The people who actually sell them. The Guardian’s Kevin Rushby talks to Stanfords cartographer Martin Greenaway, ostensibly on the occasion of the venerable map store’s move to new digs in London; Greenaway thinks that paper maps are ripe for a comeback (Stanfords does a lot of print-on-demand maps), and points out a number of other map use cases that a mobile device simply can’t be used for.

Barely Maps: Peter Gorman’s Minimalist Maps

With Barely Maps, Peter Gorman has reduced maps to their most minimalist, and their most cryptic: a grid of abstract shapes that represent the geometries of states, neighbourhoods, subway stops or intersections. Gorman started desigining them a few years ago as a side-gig, he writes. “Then, last year, my print ‘Intersections of Seattle’ went viral, and I decided to make the map-based art prints a full-time thing. Now, as I get close to 100 original maps, my next project is to compile a book of my designs, along with the stories that inspired them.” The maps are available for sale on Etsy; the book, he hopes, will be available by the end of 2019.

Old Phones, Old Maps and Old Tech

CNet’s Kent German asks people to stop tech-shaming over old phones and paper maps, though I’m not exactly sure who exactly does this (it’s not like he provides any examples). Anyway, one example he does use to bolster his argument is the time a paper map saved him from getting lost in France when his rental car’s GPS didn’t have updated maps; the graft to the larger argument in favour of not being so quick to abandon old tech in favour of the latest and greatest does leave some visible seams. (He also drags the post office into the argument. It’s Luddite potpourri.) [MAPS-L]

The argument for paper maps is getting ever more insistent, even shrill, but it seems to me to be mainly coming from the tech side of things. My impression is that the people who rely too much on mobile maps haven’t lost the ability to read maps; they never had it in the first place.

The Map Books of 2019 page lists all the books scheduled to come out this year—at least the ones I’m aware of. If there’s a book coming out in 2019 that should be on this page, let me know.

So far there are not many books listed, but that will change as the year progresses. Also keep in mind that publication dates shift all the time: keeping on top of those changes can be a sisyphean task, but I’ll do my best.
