The Ordnance Survey’s GeoDataViz team looks back at their favourite maps and data visualizations from 2021. A very wide-ranging collection, some of which are downright quirky.

Fraser Taylor Appointed to the Order of Canada
Among the 135 appointees to the Order of Canada last month was Carleton University professor Fraser Taylor, the director of Carleton’s Geomatics and Cartographic Research Centre, and coiner of the concept of “cybercartography.” See the Carleton press release.
Map Projection Explorer
Stefan Reifenberg’s Map Projection Explorer is another interactive tool that morphs a world map into the projection of your choice. The availability of data from the d3.js library seems to be enabling a lot of them. [r/Maps]

The Spilhaus Projection for Designers
The Spilhaus projection has been available to ArcGIS Pro users for nearly two years. Now, to expand the Spilhaus’s availability beyond ArcGIS users, John Nelson provides vector assets suitable for designers working in, say, Illustrator.

Natural Resources Canada Releases Updated World Map
Canada’s federal Department of Natural Resources has released a new wall map of the world, its first since 2005, under an open government licence.
The World is a general reference political map focused on the names and international boundaries of sovereign and non-sovereign countries. The information is portrayed using the Winkel II projection at a scale of 1:29 000 000. The dataset includes international boundaries, populated places, and labelled major hydrographic and physical features.
Because it’s produced by a federal department, the map and the download page are at pains to emphasize that the boundaries, labels and other information is not necessarily representative of the Government of Canada’s position (viz., Persian Gulf and Sea of Japan; disputed boundaries are included, frozen conflicts not so much).
CaGIS Map Design Competition
Submissions to the Cartography and Geographic Information Society (CaGIS)’s annual map competition, which consists of both student and professional categories, are due by 31 January 2022. (Here’s a list of last year’s winners and honourable mentions, and a gallery of some of their work. Previous years are also available.) [CCA]
Thirty Day Map Challenge
The Thirty Day Map Challenge is taking place right now on Twitter: see the #30DayMapChallenge hashtag. For the second year in a row, mapmakers are challenged to make a map based on the day’s theme. (Today’s, for example, was to map with a new tool.) It’s open to everyone; for more information and resources see the challenge’s GitHub page. Here’s the page for the 2020 challenge, which saw 7,000 maps from 1,000 contributors.
Atlas of the Invisible
Atlas of the Invisible, James Cheshire and Oliver Uberti’s collection of new maps and visualizations based on “enormous” datasets, is out today in the United States from W. W. Norton. (The British edition, published by Particular Books, came out in September.)
The Royal Geographic Society reprints a map from the book showing the flow of ice on the Greenland ice cap and interviews James about how they used the data. James has also published some education resources related to the book on his website. And of course there’s more at the book’s website.
See John Grimwade’s post about the book, in which he asks the authors about their ideas and process. Also see reviews from Fast Company and the Guardian.

Map Projection Playground
A lot of fun can be had at Florian Ledermann’s Map Projection Playground, which loads up nearly a hundred map projections for you to manipulate: controls enable you to change the centre meridian and several other parameters. You can even overlay a simplified Tissot’s indicatrix! [Maps Mania]
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.
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 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.
Esri’s New Giant Globe
“When you are a global Geographic Information Technology company with a globe in your logo, you don’t shy away from the opportunity to have a great big glorious 8.5-foot diameter illuminated rotating globe in your new office building. But what sort of globe cartography do you design? How should this gigantic model of our lovely home planet appear?” John Nelson and Sean Breyer explain the design and construction process behind Esri’s new globe—a custom Earthball manufactured by Orbis World Globes.
The Unicorn of Map Projections
It’s a shame that Sarah Battersby’s essay in The International Journal of Cartography, “The Unicorn of Map Projections,” is behind a paywall: it looks at the recent rash of map projections that purport to solve “all our mapping problems.” There have been more than a few that have claimed the title of “most accurate map”; Battersby refers to these projections as a class as unicorns. The most recent example of this I dismissed as the cartographic equivalent of a spherical cow; five years ago there was also Narukawa’s AuthaGraph map; and of course there was the Peters map.
The Spherical Cow Projection
Today is The Map Room’s 18th anniversary. When I started this blog back in March 2003, it was as an exercise in self-education: I liked maps a lot, but knew very little about them, and thought that the blogging process would enable me to learn things and share what I learned with my readers. The idea that I’m some kind of map expert is just silly: I have no professional credentials whatsoever, not in cartography, not in geospatial, not even in illustration. (I haven’t even taken geography since high school.)
But that’s not to say that I haven’t picked up some knowledge: I’ve turned my longstanding interest in fantasy maps into a few published articles (with more still in the works or in press), so I will concede the point on that front. But in general what I do have is exposure. Over the past 18 years I have seen just about everything to do with maps, and so I know a little bit about just about everything. Not enough to be employed at any map-related job, but 18 years of paying attention, of synthesizing everything I’ve seen and read, has afforded me some perspective.
Enough to call out obvious horseshit when I see it.
