Europe is in the middle of a severe heat wave. The European Space Agency has released a map of land temperatures in Europe as of 26 June, produced from the Copernicus Sentinel-3 satellite’s temperature radiometer, “which measures energy radiating from Earth’s surface in nine spectral bands—the map therefore represents temperature of the land surface, not air temperature which is normally used in forecasts. The white areas in the image are where cloud obscured readings of land temperature and the light blue patches are either low temperatures at the top of cloud or snow-covered areas.”
With the 50th anniversary of Apollo 11 almost upon us, there’s been an uptick in moon-related content, which includes moon-related map content. For example:
New Exhibition. Opening today at The Map House in London, The Mapping of the Moon: 1669-1969, an exhibition of three centuries of lunar cartography. “The exhibition includes rare early 17th and 18th Century observations of the moon from astronomers such as Athanasius Kircher and Jean-Dominique Cassini, important maps produced by NASA for lunar exploration, globes and signed material by astronauts Neil Armstrong, Buzz Aldrin, Alan Bean and Jim Lovell.” Runs until 21 July.

New Map. The July 2019 issue of National Geographic has a new map of the Moon that updates the 1969 painted version (see above) with a mosaic based on Lunar Reconnaissance Orbiter imagery. I don’t know whether that means a physical version of the map will be included with the issue as an insert, but I hope it does.
New Way to Navigate. NASA has a post on using GPS on the Moon. Now, I’d thought that using GPS on another world would require the deployment of a GPS satellite constellation around said world. No, this is about using Earth-orbiting GPS signals for lunar navigation, which simulations suggest is possible. The mind boggles.
The Wall Street Journal goes in-depth on a problem Google Maps has had for years: fake and deceptive business listings posted by scam artists that crowd out legitimate local businesses—as many as 11 million such listings at any given moment, according to experts.
Online advertising specialists identified by Google as deft fraud fighters estimated that Google Maps carries roughly 11 million falsely listed businesses on any given day, according to a Journal survey of these experts.
They say a majority of the listings for contractors, electricians, towing and car repair services, movers and lawyers, among other business categories, aren’t located at their pushpins on Google Maps. Shams among these service categories, called “duress verticals” inside Google, can snag people at their most vulnerable.
Those experts and Google disagree as to the extent of the problem. (Which is exacerbated by how easy it is to set up a business listing.) And the scam artists aren’t simply displacing local businesses: they’re resorting to outright extortion: pay up, or we’ll swamp you with bogus listings. [Engadget, The Verge]
A new study quantifies the economic benefits of GPS: in the U.S. alone, it estimates around $1.4 trillion in economic activity resulting from private-sector GPS use, about half of that coming from improvements in the telecommunications sector. (Roughly a quarter came from the telematics sector, and 15 percent from location-based services.) About 90 percent of those benefits have been generated in the last decade. The study also quantified the impact of a GPS outage: about a billion dollars a day, more if it occurred during planting season (agriculture has become reliant on GPS). [Ars Technica]
And speaking of GPS outages, earlier this month hundreds of flights were grounded over what appeared at first to be a GPS signal problem, but turned out to be a technical issue with GPS receivers made by Collins Aerospace. About 400 flights were cancelled on Sunday, 9 June, mostly involving Bombardier regional jets, but also other airliners and private aircraft. The FAA instructed pilots of affected aircraft to use other navigation methods; Collins says it has identified the issue and is working with the airlines.

The British Antarctic Survey—which despite its name focuses its attention on both polar regions—has released a new one-sheet map of Greenland and the European Arctic. The 1:4,000,000-scale map covers a region from Baffin Island to Novaya Zemlya to Scotland: a region that’s usually on the edges of maps of the Arctic and Europe rather than getting its own map. More importantly, it’s a very recent snapshot of a rapidly changing region: the retreating ice sheet in Greenland is revealing new landscapes. The map costs £12 and is available either folded or rolled from Stanfords and the Scott Polar Research Institute. [BBC]
Last week Eleanor Lutz, who gave us an old-style map of Mars in 2016 and a Goddesses of Venus map in 2017, announced her latest project: “Over the past year and a half I’ve been working on a collection of ten maps on planets, moons, and outer space. To name a few, I’ve made an animated map of the seasons on Earth, a map of Mars geology, and a map of everything in the solar system bigger than 10km.” In the coming weeks she’ll be going through each of those maps and explaining the design and source data for each. First up this week: her map of the solar system showing the orbits of every object larger than 10 km in diameter, from Mercury to the Kuiper Belt, and thousands of asteroids in between.

Om Malik’s take on the updates to Apple Maps: “all it does is remind me of Bing—an also-ran that can never catch up to Google.”
The WWDC hoopla around this tells me that Apple thinks of Apple Maps as an application, whereas in reality, maps are all about data—something Google understands better than anyone. Google maps are getting richer with data by the day. The more people use those maps to find locations, the deeper their data set gets. In my last visit to Old Delhi, I was able to find antique stores in back alleys with no difficulty at all. Apple Maps was nowhere close.
Malik suggests that Apple’s concern with their customers’ privacy may be holding back the quality of its maps relative to Google.
Google has faint regard for customer privacy, so they don’t hesitate to suck up all our data in order to build an amazing experience—so much so that many of us are willing to pay the price with regard to our personal information. Apple has a stance on privacy, which is why I am their customer, but at the end of the day, it’s an irrefutable fact that the Internet is a connected experience—and maps are part of that Internet.
Meanwhile, Reüel van der Steege has a side-by-side comparison of Apple’s upcoming Look Around feature with Google Street View.
Made a quick side-by-side comparison video driving the same road in Hawaii with 'Look Around' in Apple Maps on #iOS13 vs Google Street View. It really is "smoothly move down the street"! Impressive 🤩 #WWDC19 #iOS13Beta #AppleMaps #GoogleMaps #Apple #maps pic.twitter.com/nIA3kklhJe

M. R. O’Connor’s book Wayfinding: The Science and Mystery of How Humans Navigate the World came out in April from St. Martin’s Press. Not coincidentally, she’s published a couple of pieces on the subject of that book, both of which focus on humans’ ability to pay attention to their surroundings, and the effect that relying on GPS directions might have on that ability. In a piece for Undark, O’Connor argues that “our unshakeable trust in GPS,” which traces itself back through hundreds of years of believing in the infallibility of maps, gets us lost because we’re relying on the device rather than our senses. Her piece for the Washington Post focuses on the role of the hippocampus in navigation and spatial awareness, and the need to exercise that part of the brain.
An exhibition at BNU Strasbourg, Hors du Monde: La Carte et l’Imaginaire, explores the role of imagined places on maps, from monsters on Renaissance maps to California-as-an-island to fantasy maps. The press dossier (PDF; in French) serves as a fairly detailed guide. Opened 18 May; runs until 20 October 2019. Admission 3€.
Said features include the rebuilt map data previously announced for iOS 12 (previously: Apple Maps Data Being Completely Rebuilt for iOS 12; A Look at the Rebuilt Apple Maps) but, as they announced this week, will be available across the United States by the end of 2019, and in other countries in 2020 (see press release).
Properly new in iOS 13 is Look Around, a feature similar to Street View in that it presents a three-dimensional street-level imagery, but with what appears to be a slightly different user interface (9to5Mac).
Other features announced include favourites, sharing and other items you’d expect from an online map service: Apple is essentially doing its best to catch up and be as feature-complete as the competition. That includes upgrades to MapKit, their developer toolkit (previously).
To commemorate the 75th anniversary of the D-Day landings, the Bodleian Map Room Blog (no relation) has a post showing some of the Bodleian’s map holdings that deal with Operation Overlord. (The Bodleian has posted about D-Day before: see this post from June 2014 marking the 70th anniversary, and this post from September 2015.)
Maps Mania marks the occasion with links to the Library of Congress’s collection of World War II military situation maps and the Perry-Castañeda Library Map Collection’s D-Day map holdings.
Meanwhile, a copy of the Neptune Monograph, a top-secret intelligence report distributed to Allied commanders before the D-Day landings that contains maps of the landing zones, can be yours for a mere $45,000. Alternatively, thanks to a Kickstarter last year, you can get a reproduction for one-tenth of one percent of that price. [Military History Now]
Update: I forgot to mention this Library of Congress blog post about a fascinating model of Utah Beach used during the invasion.
