The temperature on a hot summer day in a single city can vary by as much as 11 degrees Celsius depending on where you are—whether you’re near green spaces that cool down the surrounding areas, or pavement and concrete, which absorb heat and radiate it. That’s the heat island effect, and mapping it is the focus of a project led by Portland State University researchers, funded in part by NOAA, and conducted by on-the-ground volunteers who have been taking temperature measurements across a number of U.S. cities. Those measurements have been cross-referenced with other data about the neighbourhoods, which will help cities figure out how to keep their citizens cool during heat waves—which, let’s face it, are going to be a lot more common going forward.

Earlier this year I told you about Barely Maps, the minimalist map project undertaken by Peter Gorman, who in a series of posters reduced maps to their most cryptic and abstract state. He’s been selling prints on Etsy, but now Peter has launched a Kickstarter campaign for the next phase of his project: a book that collects 100 of his minimalist maps, along with the stories behind their creation.
Peter sent me a proof copy of the book. The cover is as minimalist as you might expect from such a project. The maps are familiar if you’ve been following the Barely Maps project: here they take up an entire right-hand page, with a brief description on the facing page.
Peter is using offset printing to produce this book, which requires a 250-copy minimum print run. Supporting the Kickstarter starts at $39, which gets you one copy of the book and free U.S. shipping. Higher tiers add map prints to the cart. As I write this post, the Kickstarter is about 88 percent of the way to its $10,000 goal.
Among other things, Pasha Omelekhin’s redesign of the Berlin S-Bahn map brings the dog back: the Ringbahn’s route is roughly in the shape of a dog’s head, but in most Berlin transit maps since the 1930s it’s been shown as a circle. It also shows rivers and channels, and adds other curves to give Omelekhin’s unofficial map a flowing, organic look. [MetaFilter]
CBC News: “A group of researchers at the University of Ottawa is using Google Street View to spot instances of gentrification in the city’s neighbourhoods. […] The program looks for patterns of improvements on individual properties, such as new fences, landscaping, siding or significant renovations.” Honestly not something for which I expected Street View to have a use.
A project of Cambridge’s Violence Research Centre, the London Medieval Murder Map is an interactive map that plots 142 murders from the first half of the 14th century onto one of two maps of London: a 1572 map from Braun and Hogenberg’s Civitates Orbis Terrarum or a map of London circa 1270 published by the Historic Towns Trust in 1989. The interactive map is powered by Google Maps, but the Braun and Hogenberg is not georectified, so the pushpins shift as you toggle between the base maps. [Ars Technica]
With Barely Maps, Peter Gorman has reduced maps to their most minimalist, and their most cryptic: a grid of abstract shapes that represent the geometries of states, neighbourhoods, subway stops or intersections. Gorman started desigining them a few years ago as a side-gig, he writes. “Then, last year, my print ‘Intersections of Seattle’ went viral, and I decided to make the map-based art prints a full-time thing. Now, as I get close to 100 original maps, my next project is to compile a book of my designs, along with the stories that inspired them.” The maps are available for sale on Etsy; the book, he hopes, will be available by the end of 2019.

Maps of bus, tram and trolley networks are, I think, more likely to use geographical maps of the city’s road network as their base layer than subway and rail maps. That’s not always the case—nor has it always been the case. Take this 1947 map of London’s trolleybus and tram routes, executed by Fred J. H. Elston. Cameron Booth finds that it has “more in common with modern best practices for transit diagrams than with something that’s now 70 years old.” On the other hand, Ollie O’Brien, writing at Mapping London, thinks that this map proves that “the simplicity of the tube map doesn’t translate very well to London’s complex road network. So perhaps this is why the idea almost didn’t survive for above-ground networks, and London’s more modern bus maps (now discontinued) have always used the actual geographical network.” Christopher Wyatt, sharing the map on Twitter, notes a big, Westminster-shaped hole in the trolley network that matches London’s speed limit map: “It does seem as though there is a historical pattern of aversion to transportation equity from Westminster.”
Speaking of Washington, the D.C. Underground Atlas is a project to map all the tunnels under the city: utility, transportation and pedestrian tunnels alike, from metro and water tunnels to the underground corridors connecting congressional buildings. The maps are presented as Esri Story Maps and there’s lots of accompanying text. The project is the brainchild of Elliot Carter, who is profiled by CityLab and the Washington Post: both pieces reveal one challenge in mapping the underground infrastructure of Washington—getting past security concerns.

An exhibition at the New York Transit Museum, Navigating New York, got a writeup in Curbed New York. “The exhibit, which has been in the works for about a year, draws heavily on the NYTM’s extensive collection of objects related to the transit system—subway maps, yes, but also cartographic tools, renderings, and other ephemera. There are also items that might be familiar even to those who aren’t transit wonks, like the New Yorker’s 2001 ‘New Yorkistan’ cover by Rick Meyerowitz and Maira Kalman.” Vignelli’s famous 1972 subway map also makes an appearance. The exhibition runs through 9 September 2019; there’s no dedicated web page for it.
