Smoke and Smog

Sediment, Smoke, and Stained Ice in Quebec

Forest fires near Eastmain, Quebec had a dramatic impact on air quality around here last week; I woke up hacking and wondering why. (Air filters to maximum!) The above photo, taken by the MODIS sensor aboard NASA’s Aqua satellite on June 28, gives some idea of the situation on the eastern shores of James Bay. (The photo also shows a brown-stained James Bay, the result of tannin-stained water from bogs spilling into the bay in spring.) Image credit: NASA Earth Observatory.

Error Reporting in Apple Maps

A major feature of Apple’s forthcoming Maps application for OS X 10.9 Mavericks is enhanced error reporting. AppleInsider has the details. This was inevitable, not just because of the uneven quality of Apple’s maps and the reputational firebombing they’ve gotten since their launch last year, but because all online maps suck and need error reporting. Of course, reports are one thing; how quickly and effectively they’re acted on—that’s what’s important.

Today NASA released a set of vegetation maps based on data from the Suomi NPP satellite. Flickr photoset, YouTube video. The maps depict a year’s worth of changes in vegetation. “High values of Normalized Difference Vegetation Index, or NDVI, represent dense green functioning vegetation and low NDVI values represent sparse green vegetation or vegetation under stress from limiting conditions, such as drought.” Image credit: NASA/NOAA.

Review: Sea Monsters on Medieval and Renaissance Maps

Chet Van Duzer’s Sea Monsters on Medieval and Renaissance Maps does what it says on the tin: you really will find out more than you ever wanted to about the sea monsters that appeared on medieval and renaissance maps. (Van Duzer defines them as anything that a contemporary reader would consider exotic, whether it was real or imaginary, so walruses appear along with krakens.) It’s a dizzying catalogue of them, all kinds of them, from medieval mappaemundi (actually, there’s a Roman map in there too) all the way to Ortelius and the late sixteenth century. By the seventeenth century sea monsters were giving way to sailing vessels, and to a loss of ornamentation and illustration in general.

But: sea monsters. What was up with them? For the most part this book gets lost in the weeds, focusing in detail on monster after monster, but Van Duzer does sketch out an argument in the introduction:

First, they may serve as graphic records of literature about sea monsters, indications of possible dangers to sailors — and datapoints in the geography of the marvellous. Second, they may function as decorative elements which enliven the image of the world, suggesting in a general way that the sea can be dangerous, but more emphatically indicating and drawing attention to the vitality of the oceans and the variety of creatures in the world, and to the cartographer’s artistic talents. Of course these two roles are compatible, and sea monsters can play both at the same time. (p. 11)

Van Duzer goes beyond the map in his discussion of sea monsters. For one thing, he points out the non-cartographic sources of sea monsters, such as works of natural history, and compares them to the monsters on the map. He also looks at the economics of sea monsters, which were embellishments that cost extra and may have required a specialist artist: “if the client commissioning the chart did not pay for sea monsters, he or she did not receive them” (p. 10).

For my part, it seems to me that sea monsters in renaissance maps are also holdovers of medieval iconography, sort of a cartographic appendix. Being a big-picture sort, I glazed over a bit at all the detail, but this sort of detail is exactly the sort of thing that illuminates the subject. Between this book and The Art of the Map (reviewed here), I’ve learned quite a bit about the margins and empty spaces of old maps lately.

Apple Maps on the Mac

A Mac version of Apple’s maps was among the new features announced for Mac OS X 10.9 Mavericks at Apple’s Worldwide Developers Conference (WWDC) on Monday. Coverage: 9to5Mac, The Verge. I’m surprised to see that they’re doing it as a standalone application rather than on the Web, which is what I’d expected. One trick of the app is that you can send turn-by-turn directions to your iOS device. There’s an API, so developers will also be able to integrate the maps into their own apps. If they want. Cue old and tired jokes about Apple maps’ quality in three, two …

Review: Here Be Dragons

Stefan Ekman’s Here Be Dragons (Wesleyan University Press, February 2013) is a book-length examination of the use of maps and settings in fantasy literature. Maps and settings. Which is to say that maps are not the sole focus of this work: mark that. There are four main chapters, only one of which deals with maps; the remaining three deal with the issue of borders and territories, the relationship between nature and culture in fantasy cities, and the relationship between ruler and realm. Taken as a whole, this book discusses the role of place in fantasy.

But I won’t be discussing that whole here: I am no literary scholar, and can’t say much of value about the chapters that do not discuss maps—nothing that would rise above the level of a last-minute undergraduate paper, anyway. But maps are something I can say something about, especially fantasy maps, since I myself have been paying attention to them over the past decade, first during my time blogging at The Map Room (see the [old] Imaginary Places category) and since then more sporadically, but with more focus, for my fantasy maps project.

The Sixteenth-Century Origins of Fantasy Maps

One of the things I’m interested in for my fantasy maps project is the origin of fantasy map design: where does that tell-tale fantasy map look come from?

Look at enough fantasy maps, and it’s hard not to notice certain commonalities in design. As Stefan Ekman demonstrates in Here Be Dragons (yes, I have a review coming—soon!), the maps that accompany fantasy novels tend to be characterized by a number of typical features. “Like much high fantasy,” he writes, “the secondary-world maps follow a pseudomedieval aesthetic according to which dashes of pre-Enlightenment mapping conventions are rather routinely added to a mostly modern creation.”1 Fantasy maps look nothing like medieval maps, and can in many ways be seen as the hybrid descendent of 19th-century amateur mapmaking and early-20th-century children’s book illustrations.

A Renaissance Globemaker’s Toolbox

Book cover: A Renaissance Globemaker's Toolbox Briefly noted: A Renaissance
Globemaker’s Toolbox: Johannes Schöner and the Revolution of Modern Science
, John Hessler’s biography of German priest, astronomer and mathematician Johannes Schöner (1477-1547), an early globemaker who, among other things, created the first printed celestial globe gores as well as globe gores for Martin Waldseemüller’s world maps.

The survival of Schöner’s notes and annotations is unique in the history of cartography; not only do they show his thinking about theoretical and practical geography, but they also reveal the art of mapmaking during his lifetime. John Hessler discusses Schöner’s opinions on the canonical geography of Ptolemy, his reaction to the new discoveries of Columbus and Vespucci, and his involvement in the new astronomy of Copernicus. Schöner’s surviving notebooks, manuscripts, and associations with other scientists of the period offer unprecedented insight into the history of these materials, and into the geographical and astronomical concerns that fuelled the birth of modern science development during this critical period in its development.

Review: The Art of the Map

In The Art of the Map: An Illustrated History of Map Elements and Embellishments, retired history professor Dennis Reinhartz explores the design elements at the margins of western maps from the sixteenth to the nineteenth centuries. It is both a lavishly illustrated book and a close interrogation of the design elements used by western cartographers during the period in question.

From compass roses to cartouches, to sea monsters in the oceans and people and animals in the margins, these elements were used to fill up the otherwise empty corners of a map (of which there were many in this period), set the tone for the map, or otherwise provide information. Most of these elements are gone today (most: National Geographic still makes use of insets and commentaries). Even most fantasy maps, which ape in many ways the maps of this period, may have little more than a cartouche and a compass rose, and are spare in comparison to their historical kin.

Reinhartz organizes his book by elements: ships, sea monsters, plants, animals and people all get their own chapter. With what seems to be a rather small sample of maps, he often returns to the same, familiar maps to discuss a different element. But because The Art of the Map spans more than 300 years, we are not looking at a specific style or usage: the differences between a 16th-century portolan chart and a 19th-century bird’s-eye map of a city are quite substantial.

This book does not make a specific, scholarly argument about these map elements; it’s an appreciation of them, illuminating their essential character by repetitive example. But its intense examination of antique maps’ marginal elements may well open your eyes to, and appreciate, parts of the map that, as present-day readers with present-day map-reading habits, you may well have glossed over.

New Google Maps: First Impressions

To be honest, my first impression of the new Google Maps design was how sluggish it seemed. My iMac has a quad-core Ivy Bridge Core i5, a dedicated graphics chipset and a 20-Mbps Internet connection, so I found that a bit disappointing. I didn’t think “resource intensive” would have implications for my current setup. It seemed a little better, though not perfect, using Chrome instead of Safari; Chrome also supports integrated 3D Google Earth mode (Safari is relegated to Lite mode). Performance is going to be something to keep an eye on; I hope they can optimize it.

Eliminating whitespace gives you a nice gigantic map, which is hard to consider bad in any way, but it does feel a bit overwhelming, like there’s too much map to process. Google keeps most of the map, except for major highways, dim for the most part, highlighting relevant content for specific uses—i.e., click on a location and nearest intersecting main streets highlight, ask for directions and exit numbers appear even at high zooms. It’s very, very subtle, something you might not notice. Much of the interface is moved from the sidebar to the map: Street View is accessed by clicking the road, for example—Pegman is nowhere to be seen.

Kenneth Field has some thoughts on the new maps, particularly in terms of whether Google has succeeded in creating personalized cartography. AppleInsider’s glee at discovering the same sort of image distortions that were called out in Apple’s maps last fall is plain for anyone to see.

Have you had a chance to play with it yet?
