An incident of map vandalism roiled the Internet last week. Users of several online services, including CitiBike, Foursquare and SnapChat, discovered that New York City had been relabelled “Jewtropolis” on the services’ maps: see coverage at Gizmodo, Mashable and TechCrunch. The problem was quickly traced to Mapbox, which provides maps to these services. Mapbox, understandably upset about the act of vandalism, soon figured out what the hell happened.
The problem was traced to OpenStreetMap, one of Mapbox’s data sources. On August 10 an OSM user renamed a number of New York landmarks, as well as New York itself, after a number of alt-right and neo-Nazi memes. The edits were quickly reverted and the user blocked—on OpenStreetMap. They nevertheless entered the Mapbox review pipeline, where they were, in fact, caught and flagged on the 16th, but a human editor mistakenly okayed the renaming of New York to Jewtropolis. A simple human error, but with a delayed fuse: the edit turned up on Mapbox’s public map two weeks later. When all hell broke loose on the 30th, the map was fixed within a few hours.
Traffic. Traffic congestion is a key feature of mobile mapping, and predicting it involves looking at historical data. CityLab reports on a recent study suggests that time-of-day electricity usage patterns can be used to predict traffic congestion patterns. A household that starts using power earlier in the morning gets up earlier and presumably will go to work earlier.) It’s another variable that can be put to use in traffic modelling.
Prince Edward Island is to maps of Canada what New Zealand is to world maps: it’s left off them an awful lot, and the residents are sore about it. Now, CBC News reports that there’s an exhibition about it: Missing the Island, “[a] light-hearted look at a small selection of maps and graphics that have omitted P.E.I.,” runs until October 7 at the Confederation Centre of the Arts in Charlottetown.

Speaking of lost islands, invented places, myths and mistakes, our friend Alejandro Polanco’s latest project is this poster map of lost worlds—he calls it “the fantasy map I always dreamed of.” See his blog post (in Spanish) or the project’s Kickstarter page:
Over the last twenty years, in my work as a graphic designer and mapmaker, I have enjoyed reading numerous books on lost continents, mythological animals, phantom islands and cartographic errors. However, I have never found all those ingredients gathered in a single fantasy map. That’s why I decided to create “Lost Worlds,” a poster in which I have compiled some of the main details about lost continents, historical errors on famous maps, islands that once were believed to really exist, fantastic animals. . . . The documentation work has been meticulous and, for the final design, I have chosen the cases that I consider to be the most representative. It is, in short, a map to feed our imagination and our dreams.
Like his previous project, Minimal Geography, it’s full of inset maps and descriptive text. The main map locates lost continents, phantom islands and cryptid creatures; the inset maps include examples of old maps that contain the sorts of imaginary and erroneous features Edward Brooke-Hitching covers in The Phantom Atlas.
Alejandro is, as I mentioned, crowdfunding this map on Kickstarter, where it’s already past its (nominal) target. Available as a digital download; prices start at €6 (higher tiers include other products.
On Thursday, the World Health Organization released a map showing parts of the Democratic Republic of the Congo that are currently being affected by Ebola. The map showed four cases in Wangata, one of three “health zones” in the large city of Mbandaka. Wangata, according to the map, lies north of the main city, in a forested area on the other side of a river.
That is not where Wangata is.
“It’s actually here, in the middle of Mbandaka city,” says Cyrus Sinai, indicating a region about 8 miles farther south, on a screen that he shares with me over Skype.
Almost all the maps of the outbreak zone that have thus far been released contain mistakes of this kind. Different health organizations all seem to use their own maps, most of which contain significant discrepancies. Things are roughly in the right place, but their exact positions can be off by miles, as can the boundaries between different regions. […]
To be clear, there’s no evidence that these problems are hampering the response to the current outbreak. It’s not like doctors are showing up in the middle of the forest, wondering why they’re in the wrong place. “Everyone on the ground knows where the health zones start and end,” says Sinai. “I don’t think this will make or break the response. But you surely want the most accurate data.”

Atlas Obscura has the odd and fascinating story of how a Venetian named Nicolò Zeno created an island in the middle of the North Atlantic called Frisland, in an apparent attempt to claim that Venetian explorers had discovered the New World. After it appeared on Zeno’s 1558 map, it persisted on other maps for a century afterward (it was even claimed for England in 1580), and the existence of Frisland itself was not fully debunked for a long time after that. “The answer to Zeno’s enduring success lies not with his works, but with his audience. For centuries, people believed Zeno because they wanted to believe him. That was Zeno’s true stroke of genius. He created a story too tantalizing for people to ignore.”
Last year I told you about The Un-Discovered Islands, a book by Malachy Tallack that told the stories of some two dozen islands that were once thought real but are now no longer on the map. It existed only as a British edition, though a U.S. edition was said to be forthcoming. That U.S. edition is coming next month from Picador, so readers in North America will be able to lay hands on a copy more easily, should they wish. [Amazon]
Specifically, the center had banked on equity from New Market Tax Credits to fund the final construction payment of $1.7 million. Its leaders believed the new building at 505 Lake Street fell in a qualifying U.S. Census tract for the federal program, according to the letter.
An online map based on the building address showed it within the tract, but it turned out that the building is actually just outside it.
