Nature: “Glaciologists will soon have a treasure trove of data for exploring how Antarctica’s underbelly has changed over nearly half a century. An international team of researchers has scanned and digitized 2 million records from pioneering aeroplane radar expeditions that criss-crossed the frozen continent in the 1960s and 1970s. […] The digitized data extend the record of changes at the bottom of the ice sheet, such as the formation of channels as Antarctica’s ice flows, by more than two decades.” (Modern radar mapping of Antarctica apparently only began in the 1990s.)

The highest and lowest ranked causes are highlighted when the chart loads. These represent the cumulative ranking across all years. Lightning, a natural cause, often floats to the top, but that’s only because on the human side, the vote is split between more than twenty options. Lightning doesn’t predominate in all states, though. In Alabama, the number one cause is pyromania. In Indiana, it’s brakeshoes. In Minnesota, it’s field burning. There are a couple of overall trends, too. Smoking is going down as a cause, and powerlines are going up.
Canadian Geographic looks at the best maps it published in 2017. It did the same in 2016 and in 2015. The funny thing about the maps in these year’s-best posts is that they’re all by CG’s in-house cartographer, Chris Brackley, who the RCGS is clearly glad to have on board—and based on what I can see of his work, they should be.
Cat Rambo livetweeted some of the good bits from the online class on creating fantasy maps she taught with Alex Acks and Paul Weimer earlier this month (see previous entry), using the #mappingfantasy hashtag. Most of those good bits were common sense worldbuilding advice; by and large the intended audience is authors creating their fantasy worlds. They’re the ones who benefit most from basic geological or geographical advice, such as:
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.
NASA’s Goddard Space Flight Center produced this visualization, based on computer modelling and data from Earth observing satellites, tracking how hurricanes transport sea salt, dust, and smoke across the globe.
During the 2017 hurricane season, the storms are visible because of the sea salt that is captured by the storms. Strong winds at the surface lift the sea salt into the atmosphere and the particles are incorporated into the storm. Hurricane Irma is the first big storm that spawns off the coast of Africa. As the storm spins up, the Saharan dust is absorbed in cloud droplets and washed out of the storm as rain. This process happens with most of the storms, except for Hurricane Ophelia. Forming more northward than most storms, Ophelia traveled to the east picking up dust from the Sahara and smoke from large fires in Portugal. Retaining its tropical storm state farther northward than any system in the Atlantic, Ophelia carried the smoke and dust into Ireland and the UK.
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.”
Justin O’Beirne’s lengthy analyses of Google Maps and Apple Maps are always worth reading,1 and his latest is no exception. Looking at the rapid proliferation of buildings, areas of interest and other examples of Google’s Ground Truthing program, Justin discovers that Google’s buildings data are a product of its satellite imagery, its places of interest are a product of its Street View data, and its areas of interest (the orange-shaded areas that indicate business districts) are the result of combining those stores of data.
…so this makes AOIs a byproduct of byproducts[.]
This is bonkers, isn’t it?
Google is creating data out of data.
This is slightly more than Google’s competitors are able to match. As always, Justin’s analysis is worth reading in full, and comes complete with before/after animations that make his point visually clear.
Lakeside, released in May 2013, is a font inspired by topographical maps. The brainchild of Siyu Cao, Lakeside “is a typeface inspired by natural forms and topography. Letter forms are defined by positive and negative space, which could be compared to mountains (positive) and lakes (negative) in nature. The design is based on the language of cartography and the 3D visualization of the typeface follows the contours of each letter. The typeface could be further integrated with architecture, creating green public space that can be read from high above.” It’s not available for download—was this a proof of concept?—and it’s rather hard to see how it could be used in the real world.

But the font you use on your map should almost certainly not be so obviously mappy. There’s at least one font designed for maps. Back in 2005 I told you about Cisalpin, a humanist lineal font designed by Felix Arnold for use in cartography. It’s available for licensing on Linotype.
The year 2017 is almost at an end, but two more map books, published last month, have just come to my attention (via, as usual, the WMS’s indefatigable Bert Johnson). These, then, are very late additions to the Map Books of 2017 page:
New Lines: Critical GIS and the Trouble of the Map by Matthew W. Wilson (University of Minnesota Press). “Seeking to bridge a foundational divide within the discipline of geography—between cultural and human geographers and practitioners of Geographic Information Systems (GIS)—Wilson suggests that GIS practitioners may operate within a critical vacuum and may not fully contend with their placement within broader networks, the politics of mapping, the rise of the digital humanities, the activist possibilities of appropriating GIS technologies, and more.”
