More on Urbano Monte’s 1587 world map, which, you may remember, the Rumsey Collection digitally assembled into a single map from 60 manuscript pages. Now Visionscarto has taken it a step further, with a web tool that reprojects a map into other projections, taking the map’s original polar azimuthal equidistant projection and transmogrifying it into 20 other projections. Yes, sure, the Mercator is one of them, but so are the Goode Homolosine, the Hammer—even the Dymaxion. The tool is available on both the Visioncarto and Rumsey Collection websites. [David Rumsey]
The David Rumsey Map Collection has a number of virtual globes, but its AR Globe app may be the most unusual way to view them. Released last December for the iPhone and iPad, it uses augmented reality to superimpose one of seven celestial or terrestrial globes from the 15th through 19th centuries. The globes can be manipulated—spun, zoomed in and out—or observed from the inside (which is a good thing with celestial globes).
To be honest I’m not sold on using augmented reality to view virtual globes. It’s one thing to use AR to superimpose IKEA furniture in your living room: that makes sense, because it helps you visualize where the furniture would go and what it would look like. But it’s hard to see the utility of plunking a virtual globe in your living room: what’s the point of adding your surroundings as a backdrop? Case in point:
It’s neat but not particularly useful, is what I’m saying.
More on Urbano Monte’s 1587 world map, a copy of which the Rumsey Collection acquired last year (see previous entry). Chet Van Duzer presented his findings on the map and the mapmaker at Stanford last month, LiveScience reports. His conclusion? Monte was “both a mastermind and a copycat”—and not a very good artist, either. But the map is still very interesting. [WMS]
In the real world, Urbano Monte’s 1587 map of the world exists as a series of 60 manuscript sheets designed to be assembled into a large world map—one that would be, at 10 feet square, the largest early world map known to exist.1 As the David Rumsey Map Collection explains, “the whole map was to be stuck on a wooden panel 5 and a half brachia square (about ten feet) so that it could be revolved around a central pivot or pin through the north pole.”
But with only two copies known to exist, that ain’t happening. So what the Rumsey Collection has done, with the copy they recently acquired via Barry Ruderman, is to do it virtually, creating a digital edition of the map as a single image (see above). The digital Monte map was apparently revealed at the Ruderman Conference last October (previously).
The Rumsey Collection’s blog post has lots of images of the individual sheets, and explains how digitizing the map explains Monte’s choice of projection:
Monte wanted to show the entire earth as close as possible to a three-dimensional sphere using a two-dimensional surface. His projection does just that, notwithstanding the distortions around the south pole. Those same distortions exist in the Mercator’s world map, and by their outsized prominence on Monte’s map they gave him a vast area to indulge in all the speculations about Antarctica that proliferated in geographical descriptions in the 16th century. While Mercator’s projection became standard in years to come due to its ability to accurately measure distance and bearing, Monte’s polar projection gave a better view of the relationships of the continents and oceans.
The Mercator version of Monte’s map is here. A Google Earth KMZ file of the map as a digital globe is here. For background on Monte’s map, see the accompanying essay by Katherine Parker, “A Mind at Work” (PDF). For more coverage, see All Over the Map’s blog post.
As I mentioned earlier this month, the David Rumsey Map Center at Stanford University opens today (KQED coverage). To celebrate, there’s a grand opening and open house tonight from 6 to 7 PM at the Center, which is located on the fourth floor of Green Library. Presentations and workshops take place on the 20th and 21st, for which registration is required. That’s followed by a day-long open house on the 22nd.
The Center’s first exhibition, A Universe of Maps: Opening the David Rumsey Map Center, runs from today until 28 August (here’s the online version).

In 2009 it was announced that map collector David Rumsey, whose eponymous website has been a must-visit for any map aficionado, would be donating his collection of 150,000 maps, plus digital copies, to Stanford University. Preparations to receive Rumsey’s collection began last summer. Now the David Rumsey Map Center is set to open—an event that will be marked with a reception on 19 April, the opening of an exhibition called A Universe of Maps: Opening the David Rumsey Map Center, and a series of presentations and workshops over the following two days. Speakers include Anne Knowles, Susan Schulten and Chet Van Duzer, among others, as well as Rumsey himself. [via]
