Dee Longenbaugh, former proprietor of Observatory Books in Juneau, Alaska, died Friday at the age of 84. Observatory Books, which specialized in rare books and maps, especially pertaining to Alaska, closed in late 2016 owing to Longenbaugh’s illness; the store’s stock was later inventoried. [WMS]
Coming Soon: Kenneth Field’s Open Online Course on Cartography
Esri will be hosting a free, six-week massive open online course (MOOC) on cartography later this year. Called Cartography., it’s taught by Kenneth Field and coincides with the release of Field’s textbook of the same name.
Each weekly lesson in the Cartography. MOOC focuses on the creation of one exemplary map that draws together key cartographic ideas. Lessons consist of about two hours of content, including video discussions, guided and self-guided exercises using ArcGIS Pro and ArcGIS Online, quizzes, interactions between students and instructors, and supplemental resources. Participants who engage with all the course content will receive a certificate of completion and a discount code to purchase Cartography., the book, should they wish to continue their learning.
Registration opens on 18 April and continues until 2 May. It is, as I mentioned, free; Esri expects more than 10,000 people to sign up.
Cartography., the book, is currently scheduled to come out in June.
Strava, Responding to Security Concerns, Disables Features
Strava has reportedly disabled certain features in the wake of the privacy and security issues raised last month, with users reporting that they can no longer create workout segments. In a statement given to The Verge, Strava said: “We are reviewing features that were originally designed for athlete motivation and inspiration to ensure they cannot be compromised by people with bad intent.” [Canadian Cycling Magazine]

Freedom in the World, Mapped

The 2018 edition of Freedom House’s annual report on political rights and civil liberties, Freedom in the World, is out, and it’s illustrated by maps that categorize countries into “free,” “partly free” or “not free” and assign them a score out of 100. (I can’t say 1 to 100, because Syria is -1. According to them, it’s been a bad year for global freedom.) The main map, above, shows the three categorizations. It’s a bit reductionist: “partly free” includes Morocco (score: 39) and Bolivia (score: 67), which obscures the fact that Morocco’s score is closer to nearby Algeria’s (35, “not free”) and Bolivia’s is closer to Peru’s (73, “free”) than they are to each other. But scores and categories don’t always map cleanly to one another. A second choropleth map of the scores themselves is more granular, and more revealing:
I like maps, because they lie.
Because they give no access to the vicious truth.
Because great-heartedly, good-naturedly
they spread before me a world
not of this world.

Daily Overview
Daily Overview is a website that curates spectacular aerial and satellite imagery. Founded by Benjamin Grant, and inspired by the Overview Effect—”the sensation astronauts have when given the opportunity to look down and view the Earth as a whole,” it’s available in virtually every social media format out there; a book, Overview, came out in October 2016.

Planetary Maps for Children
Planetary Maps for Children is a collection of pictorial maps of several moons and planets of the Solar System (so far: Venus, Mars, the Moon, Io, Europa, Titan, and Pluto and Charon), aimed at younger map readers. The maps are vibrant and colourful, full of sight gags and “fabulous make-believe creatures” and other sight gags. They’re available in digital, poster and virtual globe formats and available in several languages; the whole thing is a project of the ICA’s Commission on Planetary Cartography. [via]
LIDAR Mapping Reveals a Far Greater Mayan Civilization
A 2016 aerial survey of ten sites in Guatemala’s Maya Biosphere Reserve used LIDAR to digitally remove the tree canopy from the landscape, revealing, National Geographic reports, “the ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed”—and one that likely supported a much higher population than previously thought. The survey and its findings are the subject of a documentary special premiering tomorrow on the National Geographic channel. More coverage: CBC News, The New York Times, The Verge, The Washington Post.
Are Africa and South America That Hard to Tell Apart?

Literary Maps Exhibition at Harvard’s Houghton Library
Landmarks: Maps as Literary Illustration, an exhibition of literary and fantasy maps at Harvard’s Houghton Library, is free to the public and runs through 14 April 2018. “Presented in conjunction with the bicentenary of the Harvard Map Collection, this exhibition brings together over 60 landmark literary maps, from the 200-mile-wide island in Thomas More’s Utopia to the supercontinent called the Stillness in N. K. Jemisin’s The Fifth Season. Visitors will traverse literary geographies from William Faulkner’s Yoknapatawpha County to Nuruddin Farah’s besieged Somalia; or perhaps escape the world’s bothers in Pooh’s Hundred Acre Wood.” Atlas Obscura has more on the exhibition, along with a selection of some of the maps it presents.

The Gerrymanderers
When we talk about gerrymandering, about redrawing the political map to favour one’s own party at the expense of another, we talk a lot about the maps themselves. The mapmakers, not so much. Check out this New York Times article on the political consultants who do the redrawing; it focuses on the electoral map of Maryland, which like several other states’ maps is the focus of a court challenge. The process has become even more refined as more and more data becomes available to feed into the redistricting maw.
The Times article points to a similar, earlier article that appeared in the October 2012 issue of The Atlantic and goes into even more depth: “The League of Dangerous Mapmakers.” [Leventhal]
Transport for London’s Historical Archive of Car Line Diagrams

IanVisits has stumbled across Transport for London’s cache of car line diagrams (CLDs)—the linear maps that appear inside each train car. The TfL page includes CLDs ands CLD stickers for all lines going back to 1996; each line has its own PDF file that contains every iteration of its diagram, one per page. “No one will care about this whatsoever,” says IanVisits. IanVisits is, I suspect, wrong. [WMS]
The Miami Map Fair at 25

Cape Town’s Disappearing Water Reservoirs
Cape Town is running out of drinking water, a crisis dramatically depicted by NASA Earth Observatory maps that show the depletion of the city’s reservoirs. The animated gif above, for example, “shows how dramatically Theewaterskloof [Cape Town’s largest reservoir] has been depleted between January 2014 and January 2018. The extent of the reservoir is shown with blue; non-water areas have been masked with gray in order to make it easier to distinguish how the reservoir has changed. Theewaterskloof was near full capacity in 2014. During the preceding year, the weather station at Cape Town airport tallied 682 millimeters (27 inches) of rain (515 mm is normal), making it one of the wettest years in decades. However, rains faltered in 2015, with just 325 mm falling. The next year, with 221 mm, was even worse. In 2017, the station recorded just 157 mm of rain.”
Non-Anonymized Strava User Data Is Accessible
More on the privacy issues regarding Strava’s global heat map and its customer data. Now Wired UK is reporting that Strava’s data isn’t anonymous. Because you can compare your results with nearby users, all it takes is a local GPS tracklog—which can be created out of whole cloth, as Steve Loughran’s blog post demonstrates—to see detailed information about users. Wired UK:
By uploading an altered GPS file, it’s possible to de-anonymise the company’s data and show exactly who was exercising inside the walls of some of the world’s most top-secret facilities. Once someone makes a data request for a specific geographic location—a nuclear weapons facility, for example—it’s possible to view the names, running speeds, running routes and heart rates of anyone who shared their fitness data within that area.
The leaderboard for an area, the Guardian reports, can be extremely revealing. “The leaderboard for one 600m stretch outside an airbase in Afghanistan, for instance, reveals the full names of more than 50 service members who were stationed there, and the date they ran that stretch. One of the runners set his personal best on 20 January this year, meaning he is almost certainly still stationed there.”
Which makes the security issue regarding military personnel using fitness trackers even worse than simply the anonymous aggregate of the routes they take. Yes, this is very much an unintended and unforseen consequence of relatively innocuous social sharing bumping up against operational and personal security protocols; and it’s as much on military personnel to, you know, not use GPS-enabled devices that upload your location to a third-party server as it is on companies to have clear and effective privacy controls. This is very much the result of a whole lot of people not thinking things through.
