Carbon monoxide released into the atmosphere by the California wildfires is drifting across North America in concentrations sufficient to turn up on the Atmospheric Infrared Sounder (AIRS) on NASA’s Aqua satellite. A series of maps showing CO concentrations in the United States between 30 July and 7 August, using AIRS data, have been combined into the animation above.
Landsat observations have charted the erosion of the banks of the ever-changing Padma River, a major distributary of the Ganges in Bangladesh. This is vividly shown in this animation produced by NASA Earth Observatory, which “shows 14 false-color images of the Padma river between 1988 and 2018 taken by the Landsat 5 and 8 satellites. All of the images include a combination of shortwave infrared, near infrared, and visible light to highlight differences between land and water.” More on the erosion of the Padma River here.
“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has posted maps of wildfires and evacuation zones, but they haven’t been updated in a couple of weeks and are now out of date, I fear.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.)
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?).
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.
