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.

Dan Bell’s career drawing maps of real-world places in the style of maps of J. R. R. Tolkien’s Middle-earth continues apace; a recent piece, a map of San Francisco, got written up in the San Francisco Chronicle, and his website is full of other recent works.

But computer mapping may be about to overtake hand-drawn illustration. John M. Nelson has created an ArcGIS style that does the very thing Dan Bell does by hand: emulate the maps of Middle-earth executed by Christopher Tolkien and Pauline Baynes. The style is called, naturally, My Precious: John explains it here and here, and demonstrates the style with this map of the Americas.

There are, of course, some flaws in this method: a mechanical representation of a hand-drawn style risks falling into the uncanny valley’s cartographic equivalent, especially when mountain and forest signs are clone-stamped over large areas. And to be honest I’m not a fan of the Aniron font: those letterforms were used in the Lord of the Rings movies, but never the books’ maps, and now they’re found on damn near every Tolkien-style map, and we hates it, precious, we hates it forever. But Nelson is basically emulating modern fantasy map practice: modern fantasy maps are invariably done in Illustrator, labels are computer generated rather than hand-drawn, and hill signs are clone stamped. Applying it to real-world maps, and GIS software, is new, but a difference in degree.

Google is using its Street View cars, now equipped with air-quality sensors, to measure air pollution in California on a block-by-block level.

Earlier this year, we shared the first results of this effort with pollution levels throughout the city of Oakland.

We’re just beginning to understand what’s possible with this hyper-local information and today, we’re starting to share some of our findings for the three California regions we’ve mapped: the San Francisco Bay Area, Los Angeles, and California’s Central Valley (the Street View cars drove 100,000 miles, over the course of 4,000 hours to collect this data!) Scientists and air quality specialists can use this information to assist local organizations, governments, and regulators in identifying opportunities to achieve greater air quality improvements and solutions.

Seeking Civilization: Art and Cartography, an exhibition at Gallery Wendi Norris in San Francisco, “offers a timely re-contextualization of cartographic narrative in contemporary art and dialogue. Including works ranging from deconstructed colonial maps to neon light installations documenting personal journeys in search of love, these artworks direct us towards new reflections on citizenship, power and nationhood.” Featuring art by Michael Arcega, Val Britton, Guillermo Galindo, Taraneh Hemami, Omar Mismar, Miguel Angel Ríos (above) and Adrien Segal, Seeking Civilization opened on 23 March and runs until 6 May.

During the gold rush, San Francisco was literally built on top of abandoned ships, as its waterfront was extended out into the Bay. The above map, part of the SFgenealogy site’s section on buried ships, shows the position of those ships. More at UpOut. [Michael Kodysz]

Axis Maps updated their typographic map of San Francisco last month, with bodies of water, beaches and parks seeing changes. Prints are already sold out are sold out in the UK store but still available in the U.S.; but we can still appreciate the design. [Andy Woodruff]
