The country-level data is collected from WHO, while the data of each province in China is collected from multiple sources such as China’s NHC, Mapmiao and Baidu. Notably, we also refer to CDC to verify the virus spreading status in the U.S. To make a timely data and map updates, we collect the data every 4 hours, and verify the data quality per day. In addition, we plan to provide finer-scale data from China (the county level), U.S. (the state level) and Canada (the province level) in the next version.
The case data visualized is collected from various sources, including WHO, U.S. CDC, ECDC, China CDC (CCDC), NHC and DXY. DXY is a Chinese website that aggregates NHC and local CCDC situation reports in near real-time, providing more current regional case estimates than the national level reporting organizations are capable of, and is thus used for all the mainland China cases reported in our dashboard (confirmed, suspected, recovered, deaths). U.S. cases (confirmed, suspected, recovered, deaths) are taken from the U.S. CDC, and all other country (suspected and confirmed) case data is taken from the corresponding regional health departments. The dashboard is intended to provide the public with an understanding of the outbreak situation as it unfolds, with transparent data sources.
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]
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]
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.

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.
