The previously-unknown globe, which is about the size of a grapefruit, was made from the lower halves of two ostrich eggs, and dates from the very early 1500s. Until now, it was thought that the oldest globe to show the New World was the “Lenox Globe” at the New York Public Library, but the author presents evidence that this Renaissance ostrich egg globe was actually used to cast the copper Lenox globe, putting its date c. 1504. The globe reflects the knowledge gleaned by Christopher Columbus and other very early European explorers including Amerigo Vespucci after whom America was named.
The Lenox Globe—also known as the Hunt-Lenox Globe—was cast in 1510; interestingly, prior to this announcement, it was the only map or globe to contain the phrase hic sunt dracones—here be dragons. This globe has the phrase as well. In the Washington Post coverage, two map experts—John Hessler and Chet Van Duzer—are quoted expressing a certain amount of skepticism (especially about the purported da Vinci connection). I also suspect caution is warranted here: the history of antique maps contains several examples of groundshaking discoveries that turn out to be dubious at best.
Andy Drizen’s Tube Map Live (iTunes), a free iOS app (native iPhone and iPad versions) that shows the real-time positions of London Underground trains on the iconic Tube map, using official data. Hypnotic visualization, but the app essentially promotes Drizen’s £1.99/$2.99 Tube Tracker: tapping on trains or stations calls up an advertising popup. Via TUAW.
We’re still two years from the New Horizons flyby of Pluto, but the cartography of the solar system’s most famous dwarf planet—based on Hubble imagery—is already several kinds of problematic, as Emily Lakdawalla explains in a post that also explains how the cartography of other worlds is done. (Key challenges include defining the north and south pole—which one is which?—as well as a prime meridian.)
Another data point for our consideration of what people think a fantasy map looks like, from the author of the Maptitude tumblelog: a fantasy map of Ireland, replete with, as you would expect, forests and hills. It departs from the fantasy map paradigm by using colour: red for political boundaries, blue for water. It also uses a vaguely uncial script: something we’ve seen in the movie versions of The Lord of the Rings, but less often in fantasy book maps. Not inappropriate for Ireland, though.
Two years ago, after I brought The Map Room to a close, despondent readers asked me where they could go for their map fix, now that I was denying it to them. At the time I couldn’t point to a map blog that covered maps in general, rather than a specific niche (e.g., online maps but not antique maps). Last month, though, saw the launch of Wired Map Lab, a member of the evil empire of Wired‘s science blogs. Looks like it’s off to an ambitious start.
Briefly noted: Laura Kurgan’s Close Up at a Distance: Mapping, Technology, and Politics (Zone Books, March 2013), a different look at maps built with satellite imagery, GIS and GPS data. “Poised at the intersection of art, architecture, activism, and geography, her analysis uncovers the implicit biases of the new views, the means of recording information they present, and the new spaces they have opened up. Her presentation of these maps reclaims, repurposes, and discovers new and even inadvertent uses for them, including documentary, memorial, preservation, interpretation, political, or simply aesthetic.” Via Human Scale Cities.
Map designer Max Roberts has designed subway maps for London and New York that are based on a series of concentric circles. Strictly for fun (and shock and horror), he says, but there’s an undeniable clarity to them. Via Kottke.
The European Space Agency has released a map showing the northern hemisphere’s biomass — specifically, its growing stock volume (GSV), which is the amount of wood per hectare in cubic metres. The map is based on radar images taken by the now-defunct Envisat satellite between October 2009 and February 2011.
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.
This is a list of maps related to the flooding in southern Alberta (Calgary, Canmore, Bragg Creek, High River, Okotoks, etc.). This list will be added to as needed. Feel free to contribute additional links in the comments.
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.
