Late last year I received, as a review copy, the sixth volume of the Atlas of Design. Things being what they are around here, there has been somewhat of a gap between receiving it, reading it, and saying something about it. But it’s worth saying something about that volume now, and the Atlas of Design in general, for at least one small reason I’ll get to in a moment.
I’ve mentioned the Atlas of Design series before, but it’s worth introducing it properly. Published every two years since 2012 by the North American Cartographic Information Society, the Atlas of Design is powered by volunteer editors and contributor submissions. Nobody’s getting paid for working on or appearing in these volumes—though it must be said that many of these maps are commercial ventures (posters available for sale at the mapper’s website) or works for hire (National Geographic and the Washington Post are represented in volume six), so the mapmakers aren’t doing this just for the exposure.
The Wall Street Journal is reporting that New York’s Metropolitan Transit Authority is experimenting with new network maps that adopt a diagrammatic design that harkens back to Massimo Vignelli’s 1972 design, or (frankly) to designs used by most other transit systems. The new maps appear in nine subway stations side-by-side with geographically accurate maps of the MTA system, and embed QR codes so riders can submit feedback. If the maps are positively received, they could replace the MTA’s current network map—but New York being New York, and New York’s map wars being what they’ve been for the past fifty years or so, it’s anyone’s guess how this will shake out.

Back in 1978, Massimo Vignelli and John Tauranac debated the future of New York’s subway map. That debate—which in many ways never quite ended—is now the subject of a book coming out later this month. Edited by Gary Hustwit, The New York Subway Map Debate includes a full transcript of the debate and subsequent discussion (thanks to the discovery of a lost audio recording), plus contemporary photos and new interviews. Paperback available for $40 via the link.
It looks like every map style is doomed to be replicated in ArcGIS Pro. See, for example, Warren Davidson’s Vintage Road Atlas: which renders Toronto and its surrounding area in the style of a 1950s tourist map. It’s double-sided and is designed to be folded (which is to say that there are some upside-down bits). The ArcGIS Pro style—which is called Are We There Yet? and can be downloaded here—even simulates the creases and weathering of an old folded map, though it does so a little too regularly if you look closely. (Also there are some inconsistencies in road lines and highway markers: the map is prisoner of its data.)
Last week OC Transpo, the City of Ottawa’s transit service, unveiled a new network map (PDF) that shows the transit routes that will be in effect after the new LRT opens, which is (at the moment) scheduled to take place in November. From a cartographic perspective, what’s interesting is that OC Transpo’s new map adopts a diagrammatic, non-geographical design after years of their maps simply overlaying transit lines over a city map (see, for example, the latest, pre-LRT transit map, PDF). The approach allows the map to enlarge the more densely served core and inner suburbs and shrink the larger, but less service-dense outer suburbs—which is exactly what diagrammatic transit maps of sprawling cities are good for.
Daniel Huffman had the opportunity to redesign an airline’s route map for their in-flight magazine. He came up with the above design, which in the end the client decided against, but he talks about how he came up with it in this blog post. He calls it a cartogram, because he’s expanding or shrinking the continents to account for where the routes are clustered (which I guess kind of counts); and he’s adopted what he calls a “root-and-branch” style to avoid the cluttering and overlapping of multiple lines. It’s a fascinating read, particularly if you like learning about the mapmaking process.
Transit map designer Jug Cerović has reposted a look at the state of the art of European bus network maps. “I have studied more than 250 European cities and their bus maps, and have also designed a few. Here are some observations about the state of the practice.” He groups bus maps into three categories, based on how they use colour: maps that use colour to show the technology used (bus, metro, subway); maps that use colour to indicate individual lines; and maps that use colour and width to show bus frequency. Now Jug shows examples of each, and goes through the pros and cons, but he does have some skin in this game: he’s a fan of frequency maps, which he suggests solves the problems of the other two kinds, and in fact has produced frequency maps for Luxembourg (above) and Utrecht. Definitely worth a read if you’re interested in transit map design.
Scientific American reprints a 2016 article from The Mathematical Intelligencer on an obscure, but important, corner of transit map design: how to choose a colour for a metro line. The discussion is rather math heavy (and therefore above my pay grade), but the gist is that for ease of use lines’ colours should look as different from one another as possible, and it gets more complicated as you add more lines. “Not only must the new colors be unlike the old ones, but also they must differ from each other as much as possible.” The article discusses the math involved in choosing new colours.

Most of these more common map types focus on a particular variable that is displayed. But what if you have multiple variables that you would like to present on a map at the same time?
Here is my attempt to collect examples of multivariate maps I’ve found and organize them into a loose categorization. Follow along, or dive into the references, to spur on your own investigations and inspirations!
Jim’s examples of maps that display more than one variable include 3D maps, multicolour choropleth maps, multiple small maps, and embedded charts and symbols. Useful and enlightening.
The Art of Cartographics (Goodman) is available now in the U.K. but won’t come out in North America until March 2018. The publisher describes it as “a stunning collection of maps designed in a unique way. […] This carefully curated book selects the most creative and interesting map design projects from around the world, and offers inspiration for designers and map-lovers alike. Covering themes including power, gentrification, literature, animals, plants and food, and showcasing handrawn, painted, digital, 3D sculpted and folded maps, Cartographics offers a slice of social history that is as beautiful as it is fascinating.” Buy at Amazon U.K. | Pre-order at Amazon
Also out next week: the National Geographic Atlas of Beer (National Geographic). I have no information about the quantity or quality of the maps therein, but according to the publisher the book does have some: “The most visually stunning and comprehensive beer atlas available, this richly illustrated book includes more beers and more countries than any other book of its kind. Including beer recommendations from Garrett Oliver, the famed brewmaster of Brooklyn Brewery, and written by ‘beer geographers’ Nancy Hoalst-Pullen and Mark Patterson, this indispensable guide features more than 100 illuminating maps and over 200 beautiful color photos.” Buy at Amazon
