Google Maps updates this week: wildfires are getting their own dedicated layer in Google Maps; their tree canopy coverage tool is being expanded to 100 cities; and a new Address Maker app will make it possible to bulk-add Plus Codes to locations without addresses.

The Washington Post Examines Proposed Congressional District Maps
Redistricting—and gerrymandering—is one of the blacker cartographic arts. With the release of data from the 2020 U.S. Census, and the changes in state congressional delegations—some states gain a seat or two, some states lose a seat, others are unchanged—new congressional maps are being drawn up for the 2022 elections. The Washington Post takes a look at proposed congressional district maps in Colorado, Indiana and Oregon, and what their impact may be.
The Vinland Map and Modern Mythmaking
Read David M. Perry and Matthew Gabriele’s long Smithsonian article on the conclusion that the Vinland Map is a modern forgery. Among other things, it places the map in the context of mythmaking around Viking history and an anti-Catholic, pro-northern-European narrative of American discovery that aimed to displace the Columbus story.

Union Accuses Mapbox of Retaliation
I don’t think the Mapbox unionization story is over. Last week the Mapbox Workers Union accused Mapbox of retaliating against union organizers, several of whom, they say, have been abruptly fired. Retaliation is against U.S. labour law, and they’re filing unfair labour practice charges in that vein.

‘The Vinland Map Is a Fake’
The general consensus has been for some time that the Vinland Map is a modern forgery. A battery of non-destructive tests by Yale University, which holds the map in its Beinecke Rare Book and Manuscript Library, have been performed on the map, and the results of those tests have been announced: the map is a fake.
“The Vinland Map is a fake,” said Raymond Clemens, curator of early books and manuscripts at Yale’s Beinecke Rare Book & Manuscript Library, which houses the map. “There is no reasonable doubt here. This new analysis should put the matter to rest.”
Basically, the map’s inks contain titanium compounds first used in the 1920s, and an inscription on the parchment was altered to make it seem like the map belonged in a 15th-century bound volume.

Hachure Maps in QGIS
I’m always fascinated to see old mapping techniques replicated in modern mapping software. For an example, see Robin Hawkes’s tutorial on creating hachure maps in QGIS. Which Patrick McGranahan followed to create this map of San Marino.
FCC Releases 4G/LTE Availability Map
Last month the U.S. Federal Communications Commission released an interactive map showing 4G/LTE cellular voice and data coverage in the United States from the four major providers. This is the first FCC map released under the 2020 Broadband DATA Act, which mandated better maps than the FCC has been producing in the past (previously). [The Verge]
Latitude, Longitude and Decimal Points
Vladimir Agafonkin’s post, which demonstrates just what latitude and longitude to x decimal places looks like, is a visual complement to xkcd’s comic about coordinate precision: both tell you that when it comes to latitude and longitude, more than a few decimal points is pointless. “As you’ve probably guessed, 6 digits should be enough for most digital cartography needs (spanning around 10 centimeters). Maybe 7 for LiDAR, but that’s it.”
A Project to Restore a 19th-Century Treatise on Hand-drawn Mapping
“I have a new mapping project on Kickstarter,” writes our friend Alejandro Polanco. “This time it is about recovering some exciting hand-drawn maps by a forgotten craftsman from the 19th century.” This is Alejandro’s second project to digitally recover a 19th-century illustrated book; this time his target is an 1890 edition of a treatise on topographical drawing by Juan Papell y Llenas. The book is full of detailed examples of mapping techniques done only with ink on paper. Alejandro’s restored edition, The Art of Hand-drawn Maps 1890, will be released this fall in digital (€18 pledge) and paper (€32) editions.
Alejandro’s previous crowdfunding projects include Pandemic Atlas, The Minimal Geography Atlas, Minimal Geography and Maptorian.
Mapping ICU Capacity During the Delta Wave
Thanks to a combination of low vaccination rates and the COVID-19 Delta variant, intensive care wards are filling up across the United States. The New York Times maps one of the more disturbing metrics of the pandemic: the percentage of occupied ICU beds by hospital region.
Mapping Racial Population Shifts in the United States
As part of its extensive coverage of the 2020 census, the Washington Post maps the changes in the U.S.’s ethnic/racial makeup, and where it’s been changing.
MapQuest to the Rescue?
Adam Engst of TidBITS had a specific routing problem that only one map app could solve. The answer, as they say, will surprise you: “When faced with needing to visit 43 different addresses, what was the most efficient route? It’s easy enough to enter an address into Apple’s Maps or Google Maps, and even add an extra stop or two. But 43 stops in an optimal route? […] A little research revealed that MapQuest—remember MapQuest from the days when we all printed directions?—offers precisely what I needed.”
A Flurry of New Book Announcements
News about upcoming map books has been thin on the ground of late, which is hardly surprising given the havoc the pandemic has wreaked on the publishing industry as a whole. But in just the past two days we’ve seen three significant new book announcements.
Kenneth Field’s long-awaited Thematic Mapping: 101 Ways to Visualise Empirical Data, which takes as its starting point a map of a single event—the 2016 U.S. presidential election—will be out from Esri Press as an ebook on the 31st of August, Ken announced yesterday. Pre-order: Amazon (Canada, UK).
You might remember James Cheshire and Oliver Uberti’s amazing 2016 book Where the Animals Go. Their next book of data visualizations, Atlas of the Invisible, will be out in September from Particular Books in the U.K. and in November from W. W. Norton in North America. Pre-order: Amazon (Canada, UK), Bookshop.
The Quarantine Atlas: Mapping Life under COVID-19 is the byproduct of CityLab’s 2020 project soliciting hand-drawn maps of life under quarantine (previously here and here). In the book version, Laura Bliss matches 65 of those submissions with original essays. Due out in April 2022 from Black Dog & Leventhal. Pre-order: Amazon (Canada).
I’ve updated the Map Books of 2021 page with these books; that page still looks awfully sparse compared with previous years. If there’s a map-related book coming out this year that I haven’t listed, please let me know.
Mapbox Union Drive Fails
The results of the Mapbox unionization vote were announced today: Mapbox employees have voted 123 to 81 against forming a union. More at Protocol and Reuters.

Vaccination Rates in Montreal

Interactive maps produced by Radio-Canada from Montreal Public Health data show where vaccination rates on the Island of Montreal are lagging. The Quebec government’s target is to have at least 75 percent of the population vaccinated. Of the 3,000 sectors on the map, 70 percent have reached that goal for the first dose and 3 percent for the second.
These data are useful in terms of where to target mobile clinics and other vaccination outreach programs. I’d love to see this for other cities in Quebec, especially the one nearest to me: Gatineau’s current rate is relatively low (66.4 percent first dose, 51.2 second dose as of this week) and it’d be revealing to see where the uptake is stronger or weaker.
