“Google wants to know where you go so badly that it records your movements even when you explicitly tell it not to,” the Associated Press reports. Their exclusive investigation discovered that “many Google services on Android devices and iPhones store your location data even if you’ve used a privacy setting that says it will prevent Google from doing so.” Basically, turning the “Location History” feature off doesn’t stop Google apps from recording your location at various junctures: your location data may still be found in places like “My Activity” or “Web and App Activity,” for example. Google insists its descriptions are clear; critics are calling Google’s hairsplitting disingenuous, disturbing and wrong.
British Columbia isn’t having a very good year either, forest fire wise. For maps of the wildfires burning in the province, see the B.C. Wildfire Service’s interactive map, which shows active wildfires, fire perimeters, and evacuation areas. Evacuation maps are frequently tweeted by Emergency Info BC. Data journalist Tara Carman has posted maps of wildfires and evacuation zones, but they haven’t been updated in a couple of weeks and are now out of date, I fear.

Entrepreneur magazine profiles Peter Bellerby, the founder of globemaking company Bellerby and Company. We’ve seen a lot of Bellerby profiles over the past few years, but this one goes into more depth than most. The story of the company’s founding (Peter wanted to make a globe for his father’s 80th birthday, et cetera) is retold, but we get some more detail about the size and volume of its business today: “This year, the company should turn around about 750 globes, compared to 500 last year—and the current wait list stands between six months and two years depending on globe size. Revenue-wise, the company will likely net about 3 million pounds (close to $4 million) in 2018.” That’s … that’s something. [WMS]
A new edition of Star Trek: Stellar Cartography is coming out in October, TrekCore reports. Like The Lands of Ice and Fire, it’s a collection of folded maps—10 of them, 12″×36″ in size—rather than a bound atlas. The new edition, authored by Larry Nemecek, corrects errors and typos and adds material from the various series, including season one of Discovery. (The first edition came out in 2013.)

In 2014 cartographer Tom Patterson and his colleagues, Bojan Šavrič and Bernhard Jenny, introduced the eponymous Patterson projection, a cylindrical projection that reduced polar exaggeration while maintaining the familiar shape of continents.1 Patterson, who recently retired from the U.S. National Park Service, has teamed up with Šavrič and Jenny to produce a new projection: the Equal Earth projection.
This projection can be seen as the cartographer’s response to the Peters map: in fact, the team created it in reaction to the furor over the Gall-Peters projection being adopted by Boston public schools. “Our message—that Gall-Peters is not the only equal-area projection—was not getting through,” the authors wrote in the International Journal of Geographical Information Science (mirrored here). “We searched for alternative equal-area map projections for world maps, but could not find any that met all our aesthetic criteria.” Citing their own research into map readers’ projection preferences, they decided against projections like the Eckert IV, Mollweide and sinusoidal and opted to make their own: “a new projection that would have more ‘eye appeal’ compared to existing equal-area projections and to give it the catchy name Equal Earth.”
The end result is a Robinson-like pseudocylindrical projection that nevertheless preserves area—and, like the Robinson, is nicer to look at than a cylindrical equal-area projection like the Gall-Peters. It’s actually kind of impressive that they were able to square that particular circle. The article details their decision-making process and the math behind the projection and is worth a read. It’ll be interesting to see whether this map gains any traction. I wish it well.

Bloomberg explores land use in the United States with a series of low-resolution maps that become more and more like infographics in the shape of the lower 48 states. It’s a revealing look at the big picture, with some surprises: 41 percent of U.S. land is used to feed livestock.
Here’s a short video from the British Museum about a 13th-century celestial globe; it goes into the history of the globe, who made it, and how the stars appear on it (i.e. if the sky is represented as a globe, we’re on the inside: how do the stars appear on that globe?).
Earlier this year Google Maps changed the terms of its API and in the process jacked up its prices, leaving web developers to consider other alternatives. These include (among others) OpenStreetMap, which posted a switching guide in June; Apple, which announced its API for websites that same month; and Here Maps, which (a) is still around1 and (b) has announced a freemium plan with reasonably generous transaction limits. As Engadget points out, Google’s trying to profit off its market dominance; its competitors, seeing an opening, are making their move. [Engadget]
Google is assigning names to neighbourhoods that, the New York Times reports, have little basis in reality—but once on Google Maps, those names swiftly come into a popular usage they never had before. The East Cut, in San Francisco, was the product of a branding agency; Fiskhorn, in Detroit, is actually a misspelling of Fishkorn, taken from a typo in the source map. (Searching for “Fishkorn” works just as well, though.) How such names end up on Google Maps, and therefore get a certain canonicity, is what’s interesting: it seems to be the result of a tech giant processing diverse data with remote fact checkers and not much in the way of local knowledge.

Hey look, GIS people: Randall Munroe made an xkcd comic just for you.
In the wake of reports that fitness apps’ user data was exposed and could be used to identify military and intelligence personnel in sensitive areas like bases and deployment zones, U.S. military and defense employees can no longer use geolocation features in devices and apps in operational areas. The new policy was announced last Friday. Also see coverage at Stars and Stripes. [Gizmodo]

The Washington Post maps the largest of the wildfires burning in northern California: the Carr Fire threatening the city of Redding and surrounding communities. The Redding Record Searchlight has drone footage of the destruction wreaked by the Carr Fire in Shasta County. NASA has natural and false-colour imagery (Earth Observatory, Visible Earth) of the Carr Fire, as well as the Ranch and River Fires to the south, the so-called Mendocino Complex. See the Mercury News’s fire map of the Mendocino Complex, whose two fires’ combined acreage is now larger than the Carr Fire. Meanwhile, German astronaut Alexander Gerst observed the California wildfires from the International Space Station. [San Francisco Chronicle]
Web mapping uses Web Mercator. As Kenneth Field points out, this is fine at large scales, but at small scales you end up replicating the problem of using the Mercator projection on a wall map of the world.1 Zoom out in Apple Maps: using the map layer you get a Mercator; using imagery you get a virtual globe (basically, an orthographic projection you can spin). Ditto in Google Earth. But Google Maps, after some tests and starts, now does this in its map layer—and not just in Chrome, either. This means, among other things, that Antarctica is usably visible, as are the Arctic regions—and, of course, Greenland is its proper size at small scales.
At the Edinburgh Fringe Festival? You may want to check out The OS Map Fan Club, an hour-long solo performance about Ordnance Survey maps that sounds relevant to our interests. Written and performed by Helen Wood, The OS Map Fan Club has been making the fringe and festival circuit this year and has been getting good reviews (see here, here and here). At the Edinburgh Fringe until 18 August; details and tickets here. [Map of the Week]
