China’s Beidou satellite navigation system—a competitor to GPS like Russia’s GLONASS and Europe’s Galileo—will be complete by June 2020, when the constellation’s final two satellites are launched, the Associated Press reports. Twenty-four satellites have already been orbited. Whereas the first two iterations of Beidou offered regional coverage, this third iteration will cover the globe when complete. [Engadget, TechCrunch]
Someone is spoofing GPS signals in Shanghai, and we’re not entirely sure why they’re doing it, or how. One ostensibly bizarre theory: sand thieves trying to obfuscate illegal dredging by zonking out the GPS received by other ships’ AIS transponders. But how they’re redesignating ship (and bicycle) GPS locations into riverside circles, rather than, say, shifting everyone’s position a few kilometres away, has not yet been figured out. [MetaFilter]
Meanwhile, Typhoon Mangkhut has hit the Philippines and is moving toward China. The New York Times has a map tracking the storm’s path; NASA has posted a number of visible-light and infrared images of the storm as well.
Self-driving cars require insanely detailed maps in order to function. But, as The Drive’s Stephen Edelstein writes, “The Chinese government is blocking foreign companies from mapping its roads in great detail, according to a Financial Times report. The restrictions, which reportedly do not apply to Chinese firms, are being instituted in the name of national security. China is concerned about spying.” Mapping, geotagging, geographic surveys—all of these have been subject to Chinese government restrictions for many years (recall the trouble Google Maps has had operating in China), so this is more of an additional data point than an actual surprise.

“A huge colored map of the Silk Road from a royal court of the mid-Ming Dynasty was officially welcomed home at the Forbidden City in Beijing on Thursday,” China Daily reports. “The 30-meter-long by 59-centimeter-wide scroll, named the Landscape Map of the Silk Road, is painted on silk. It depicts trade routes starting at Jiayuguan—at the western end of the Great Wall during the Ming Dynasty (1368-1644)—through Central and West Asia to the Middle East.” The map had been purchased by a Japanese collector in the 1930s; it passed through several Chinese collectors’ hands in the 2000s until Hong Kong real estate magnate Hui Wing Mau paid $20 million for it earlier this year before donating it to the Palace Museum.

Using old maps as “proof” of one side’s claim over disputed territory, or a disputed place name, is something we’ve seen many times before. It’s happening with the Paracel Islands as well. They’re claimed (and occupied) by China as part of their claim on the South China Sea (the Nine-Dash Line); Vietnam considers the islands as part of Đà Nẵng province. While the central Vietnamese government has been somewhat careful regarding its boundary dispute with China, the same cannot be said for Đà Nẵng’s government, which has asked a local historian, Tran Duc Anh Son, to collect old maps and documents supporting Vietnam’s claims to the islands (which it calls the Hoàng Sa Archipelago). The New York Times has the story. [WMS]

Two related map exhibitions are taking place right now in the Netherlands. Mapping Japan runs until 26 November at the Japan Museum SieboldHuis in Leiden. Its focus is on 18th- and 19th-century Japanese maps from the Leiden University Libraries’ collections. “The impressive scroll painting of the Japanese coast and the personal maps belonging to Philipp Franz van Siebold (on display for the first time) are unquestionably the highlights of this exhibition.” (Possessing those maps got Siebold in considerable trouble in Japan.) Also in Leiden, Mapping Asia runs until 14 January 2018 at the Museum Volkenkunde. Its focus is on the objectivity (or lack thereof) in cartography, and features maps of both European and Asian origin. One highlight is a digitally reconstructed map of the Chinese Empire. [WMS/WMS]
The Selden Map is a map of Chinese origin bequeathed by John Selden to the Bodleian Library in 1659. The precise origins of the map have hitherto been unknown, but scientists at Nottingham Trent University are trying to do something about that. Using a series of non-invasive techniques to examine the map’s material composition, they conclude that the map was created in stages, and probably comes from Aceh, Sumatra. Their findings were published last year in Heritage Science. [Caitlin Dempsey/WMS]

Two dark, torn illustrations found in the garage of a Palm Springs home and listed for sale as “two 19th century hand colored prints of the world” turned out to be something quite possibly a bit more significant. First identified as two panels (of six) from a 1708 Korean map, Kim Jin-yeo’s Gonyeomangukjeondo (곤여만국전도), which is a derivative of Matteo Ricci’s famous Kunyu Wanguo Quantu (aka the “Impossible Black Tulip”), the panels ended up selling earlier this month for $24,000; the buyer, map dealer Barry Ruderman, is restoring the map for sale and suspects that it may in fact be a 17th-century Chinese copy rather than a Korean map.

This Taipei Times article suggests that some copies of the Ricci map—Matteo Ricci’s 1602 map of the world produced for the Chinese emperor—have been altered, possibly to support (or at least not contradict) the present-day Chinese territorial claim to the Spratly Islands (and the nine-dash line). In particular, the article claims, the James Ford Bell Trust’s copy of the map has been altered:
Part of the legend reading “between the 15th and 42nd parallels” had been erased, with ocean patterns painted over the erasure. […] Whether this is a recent defacement done to obliterate evidence that China’s historical primacy in the South China Sea is a modern fiction, or an ancient one done to eliminate an error, is a subject for further research. […] Nonetheless, several other 16th century copies of the Ricci-Li map exist in Europe, South Korea and Japan, and all display the legend intact.
To be honest, the article isn’t so much making a case as it is casting some aspersions. It has an agenda: to shoot down the argument that China’s claims to the Spratly Islands are supported by the historical record. The Ricci map—like so many other maps caught up in territorial disputes and conspiracy theories—is simply a means to an end. [WMS/Leventhal Map Center]
The show includes portraits of both as well as a half-dozen books to evoke the libraries each brought and the impact they had. Most helpful, however, are two large touchscreens, one for each map, that allow us to access translations and summaries of many of the texts. This quickly becomes addictive, because the journey is full of surprises. Here, we read about scientific theories or descriptions based on travelers’ accounts. There, we learn how best to capture a unicorn.
Two important seventeenth-century world maps are the focus of a new exhibition opening this Friday at the Asian Art Museum in San Francisco. China at the Center: Rare Ricci and Verbiest World Maps, which runs from 4 March to 8 May 2016, features Matteo Ricci’s 1602 map and Ferdinand Verbiest’s 1674 map.
Ricci (1552–1610) and Verbiest (1623–1688) were both Jesuit priests, in China to spread Christianity; their maps, produced in collaboration with Chinese calligraphers, artists and printers, produced a fundamental rethinking of China’s place in the world. Not that China wasn’t at the centre of these maps, as the essays in the accompanying catalogue point out, but these maps filled out the rest of the world, which was previously a marginal afterthought in Chinese cartography.
The Nation has a long article by Paula Findlen on the Selden Map, a Chinese watercolour map acquired by the 17th-century jurist and scholar John Selden and bequeathed to the Bodleian Library in 1659. Findlen recounts the origins of the map and its rediscovery in the Bodleian’s vaults in 2008, and describes it in intricate detail. [via]
The map’s rediscovery has set off a flurry of interest and publications (see book list below). Findlen also looks at the scholarly debates about the map.Brook and Batchelor have both written books about the Selden map, and each scholar takes a somewhat different approach to framing the story and to interpreting a reconstruction of the document’s origins. Yet they concur that this is a Chinese maritime map and a product of late-Ming ambitions, enterprise, and mobility,” she writes.
