Hotter than usual? Yes. This map shows how much land surface temperatures during the week of June 17-24, 2012 have been above or below the average for 2000-2011. Now this map measures something very specific: land surface temperatures (LSTs) aren’t the same as air temperatures: “LSTs indicate how hot the surface of the Earth would feel to the touch. From a satellite vantage point, the ‘surface’ includes a number of materials that capture and retain heat, such as desert sand, the dark roof of a building, or the pavement of a road. As a result, daytime land surface temperatures are usually higher than air temperatures.” Via Bad Astronomy.
I knew that Swedish literary scholar Stefan Ekman has been studying fantasy maps—see, for example, this blog post of his—but I only found out today (thanks to the Locus forthcoming books listings) that he has a book coming out on the subject: Here Be Dragons: Exploring Fantasy Maps and Settings will be published by Wesleyan University Press in January 2013.
The publisher calls it the “first in-depth study of the use of landscape in fantasy literature”; here’s an excerpt from their description:
In Here Be Dragons, Stefan Ekman provides a wide-ranging survey of the ubiquitous fantasy map as the point of departure for an in-depth discussion of what such maps can tell us about what is important in the fictional worlds and the stories that take place there. With particular focus on J. R. R. Tolkien’s The Lord of the Rings, Ekman shows how fantasy settings deserve serious attention from both readers and critics. Includes insightful readings of works by Steven Brust, Garth Nix, Robert Holdstock, Terry Pratchett, Charles de Lint, China Miéville, Patricia McKillip, Tim Powers, Lisa Goldstein, Steven R. Donaldson, Robert Jordan, and Neil Gaiman and Charles Vess.
I’m not sure I can overstate how much I’m looking forward to reading this. Once I do, I’ll tell you all about it.
So last week Google held a press event outlining several upcoming features and innovations in Google Maps, including the ability to use maps offline on Android (i.e., without a network connection), some pretty impressive 3D imagery, and shrinking the Street View camera so that it’ll fit in a backpack. The event was widely seen as a way to grab some of the limelight prior to Apple’s announcement of its own built-in maps for iOS, which came today (more on which in a moment).
When Rachel Hewitt’s Map of a Nation was published in the U.K. in 2010, I despaired of ever being able to lay hands on a copy easily. A book documenting the first century or so of the history of the Ordnance Survey, Britain’s national map-making body, is not likely to have much commercial potential outside Britain:
no surprise that a U.S. edition has not come out. [Update: A paperback edition became available in the U.S. in 2013, after this review was posted.] But I recently discovered that, like at least one other book otherwise unavailable on this continent, it is available to North Americans as an ebook (and has been for a year: see how observant I am). So spent the $10, downloaded it to my Kindle, and settled in to read a book I’d heard about for years but didn’t imagine I’d be able to lay hands on without some effort.
Inasmuch as a history of field surveying and copper-plate engraving can be made anything other than dull, Hewitt has managed to produce a narrative that fairly crackles with interest. She starts at the bloody Battle of Culloden, not only as a way of setting the stage for the Military Survey of Scotland, a predecessor to the OS, but also as a rationale for mapping the whole of Britain’s territory in the first place. From there we’re led through the Scottish Highlands, joint French-British observations to measure the distance between their observatories, the triangulation of Britain and the survey of Ireland. The narrative closes with the publication of the last maps of the First Series and the expansion of the OS’s works into city maps. Along the way we get glimpses into the equipment used in the survey, such as the theodolite, and the mapmaking process; there’s a lovely section on how the OS dealt with Irish placenames, and digressions into art and poetry.
It does read a bit traditionally, in the sense that it is an institutional history seen through the lens of those in charge. It’s a history of those making the maps; the impact of those maps is less thoroughly covered. And if you ask me, it ends too soon — just as the OS is getting started. A lot more could still be written, I think.
There are rumours that for iOS 6, the next version of the operating system for the iPhone, iPad and iPod touch, Apple will replace Google Maps with an in-house mapping application with an impressive 3D mode; the app will apparently “blow your head off,” to quote John Paczkowski’s source. Much is being made of the 3D mapping possibilities, thanks to Apple’s acquisition of C3 Technologies. My interest, and my concern, is with the base mapping data. If this is going to be a flagship product, and signs point to that being the case, Apple can’t use OpenStreetMap (as it does with the iOS iPhoto app), at least not exclusively: it’s still not ready. It would be better, but not cheaper, if Apple used Navteq or Tele Atlas map data directly; when Google abandoned them for their own map data, Google Maps’ quality did not universally improve.

A patch on a 16th-century map may suggest what happened to the lost colony of Roanoke. The map in question is the 1585 Virginea Pars map by John White. Based on the patch, which hides a symbol indicating a fort, researchers argue that the settlers may have moved westward and inland. AP coverage: ArtDaily, CBC, Washington Post. Via io9.
County-by-county life expectancy estimates released last month by the Institute for Health Metrics and Evaluation reveal a startling gap between the longest-lived and shortest-lived areas of the country: the difference can be as much as 15 years.
The range of life expectancies is so broad that in some counties, such as Stearns, Minnesota, lifespans rival some of the places where people live the longest—Japan, Hong Kong, and France—while in other counties, life expectancies are lower than places that spend far less on health care—Egypt, Indonesia, and Colombia. Even within states, there are large disparities. Women in Fairfax, Virginia, have among the best life expectancies in the world at 84.1 years, while in Sussex, Virginia, they have among the worst at 75.9 years.
And the situation isn’t improving either: “In 661 counties, life expectancy stopped dead or went backwards for women since 1999. By comparison, life expectancy for men stopped or reversed in 166 counties.” When people refer to the U.S. as a Third World country, this sort of thing—the disparity, the decline—is usually one of the reasons why.

Calling it “the first entirely new globe of the lunar surface in more than 40 years,” Sky and Telescope has announced a new Moon globe based on Lunar Reconnaissance Orbiter imagery. Replogle’s Moon globe has been the standard for decades, but it’s based on 1960s-era charts and, as I said in my review three years ago, doesn’t have a lot of contrast and doesn’t look much like the Moon. Mind you, the new globe costs almost twice as much.
Alejandro Polanco Masa, whose map blog La Cartoteca is one of the finest on the subject in any language, has announced the availability of his speculative fiction novel El Viaje de Argos, in which maps play a prominent role. Here’s the description in Spanish:
Desde antiguo un enigmático astro llamado Argos siembra la atmósfera con una substancia muy especial. Sólo un pequeño grupo de sabios sabe cómo recolectar y emplear esa esencia de los cielos que permite la vida eterna. Pero en pleno auge de la Roma imperial, un desastre sacude a la hermandad de sabios. Desperdigados por el mundo y sin los conocimientos necesarios para mantener la inmortalidad, vagarán sin rumbo, condenados al olvido. Hasta que en el siglo XXI, una inquieta historiadora, Irene Abad, descubre un antiguo mapa que, sin saberlo, conduce hasta el peligroso secreto que los Hijos de Argos han perseguido durante dos milenios.
I wish I could say more about this, but I never studied Spanish and can barely navigate Spanish-language websites, much less read novels. El Viaje de Argos is available in ebook form via Amazon and iBooks.
More information today on a book I’d heard was coming: The Lands of Ice and Fire, a definitive atlas of George R. R. Martin‘s fantasy world from A Song of Ice and Fire (A Game of Thrones, et cetera). The publisher: “The centerpiece of this gorgeous collection is guaranteed to be a must-have for any fan: the complete map of the known world, joining the lands of the Seven Kingdoms and the lands across the Narrow Sea for the first time in series history.” Fantasy and roleplaying game cartographer Jon Roberts is working on the project. It won’t be out until October, but you can already pre-order it at Amazon.

The ability to use other map styles with OpenStreetMap data is, I think, underexploited. I’m starting to hate the default Mapnik tiles. Stamen Design has released three different—vividly different—map styles for OpenStreetmap: watercolour tiles (above), high-contrast black-and-white, and shaded terrain. Via Daring Fireball.
You may have seen this already: a beautiful, painting-like visualization of the world’s surface ocean currents between June 2005 and November 2007, which NASA posted last month. The visualization is based on model data from the ECCO2 project. See also this short video on Flickr (Flash required). Image credit: NASA/
“In the 18th and 19th centuries, children were taught geography by making their own maps, usually copies of maps available to them in books and atlases at their schools or homes,” says a David Rumsey Collection post from January 2010 that is for some reason drawing attention right now. “These old maps made by children were hand drawn and colored, one-of-a-kind productions, and it is amazing that any have survived down to our time. That they have is due to luck and the efforts of families to preserve the history of their children.” Anyone interested in hand-drawn maps will like these; for my part I can’t get over the similarity in style between these maps and later fantasy maps.
