Geographer Christopher Winters maps car ownership—or rather the lack thereof—in The Geography of Carfree Households in the United States. In only a few census tract do more than 75 percent of the population go without owning a car. Not surprisingly, most of them are in New York, plus other densely populated cities: “New York has many more such households than any other urban area. It’s the one large place in the United States where only a minority of households have a vehicle available.”
A Redistricting Roundup
Gerrymandering in Texas
The New York Times and Texas Monthly look at the bizarre shapes in the new congressional electoral map of Texas, which gains two new representatives. Texas Monthly’s Dan Solomon: “Across the state, there will be one more majority-Anglo district than under the prior map, and one fewer majority-Hispanic one. The two new seats Texas was awarded for its booming population will be placed in Austin and Houston—and even though non-Anglo newcomers made up 95 percent of the state’s population growth the last decade, both districts will be Anglo-majority.” Kenneth Field has some thoughts.

Making Redistricting More Fair
A Surge of Citizen Activism Amps Up the Fight Against Gerrymandering (Bloomberg): “From North Carolina to Michigan to California, voting rights groups, good government advocates, data crunchers and concerned voices are finding new ways into the fight for fair representation, via informational meetings, mapping contests, testimony workshops and new technologies.”
Can Math Make Redistricting More Fair? (CU Boulder Today): “Clelland doesn’t advocate for any political party or for any particular redistricting proposal. Instead, she and her colleagues use mathematical models to build a series of redistricting statistics. These numbers give redistricting officials a baseline that they can compare their own maps to, potentially identifying cases of gerrymandering before they’re inked into law.”

A Map of Every Chinese City
Inspired, he says, by Itchy Feet’s maps of Every European City and Every American City, Alfred Twu has come up with a Map of Every Chinese City. (Chinese version here.) Twu is no stranger to these parts: he worked on rail maps for California and the Northeast Corridor some years back.

Niehues Moves On from Ski Resort Maps
Legendary ski resort map artist James Niehues has announced on his blog and on Twitter that he will be “stepping away from creating ski resort trail maps” after more than three decades. He plans to work on other projects, including the American Landscape Project, and will, for the first time, be selling original paintings and sketches of his ski resort trail maps later this month.

Google Maps Announcements
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.
