Britain had the Ordnance Survey, France the Cassini family. Japan had Inō Tadataka (伊能 忠敬, 1745-1818), who over a series of expeditions in the early 19th century conducted a systematic survey of Japan using modern techniques. Writing for Nippon.com, Inō’s biographer, Hoshino Yoshihisa, writes a long introduction to Inō’s life and work that is well worth the read. [Tony Campbell]

A nice, accessible (if overboosterish) history and overview of Google Earth—which despite its deprecation on the desktop is still a thing—from Sarvish Mathi at OneZero. [GIS Lounge] Related: this Google blog post on their imagery, how they get it and how it’s processed.
Simon Weckert created a virtual traffic jam in Berlin by pulling 99 used smartphones in a wagon: a large number of phones moving slowly looks like a traffic jam to Google Maps. “Through this activity, it is possible to turn a green street red which has an impact in the physical world by navigating cars on another route to avoid being stuck in traffic.”
Google’s statement to 9to5Google suggests that they’re taking Simon’s hack in stride: “Traffic data in Google Maps is refreshed continuously thanks to information from a variety of sources, including aggregated anonymized data from people who have location services turned on and contributions from the Google Maps community. We’ve launched the ability to distinguish between cars and motorcycles in several countries including India, Indonesia and Egypt, though we haven’t quite cracked traveling by wagon. We appreciate seeing creative uses of Google Maps like this as it helps us make maps work better over time.”
So people fed up with traffic being rerouted onto their residential streets could, conceivably, hack that traffic elsewhere—but not for much longer.
A new unified geologic map of the Moon, based on digital renovations that updated 1970s-era geologic maps to match more recent topographic and image data gathered by lunar orbiters, was released by the USGS last month. The map is “a seamless, globally consistent, 1:5,000,000-scale geologic map”; the paper version (25 MB JPEG) provides azimuthal projections beyond the 55th parallels and an equirectangular projection between the 57th parallels.

Last year Apple rolled out its new map data in stages, with new coverage being added on a state-by-state or region-by-region basis. Yesterday Apple announced that its new map data now covers the entire United States (except, Justin O’Beirne points out, the territories). This is slightly later than the end-of-2019 target they’d been aiming for. Europe is scheduled to start receiving the new map data this year.
Matthew Panzarino, who broke the news in 2018 that Apple was building its own map data, said in a tweet that “Maps is probably the biggest software turnaround in Apple’s modern era—an interesting case study for a company that rarely needs turnaround efforts.”
George Louis Le Rouge, Plan de l’Armée de Cornwallis attaquée et faitte Prisoniere dans York Town, le 19 8bre, par l’Armée Combinée Francaise et Americaine, 1781. Map, 34.9 x 43.5 cm. Royal Collection Trust.
More than 2,000 military maps and related items collected by George III have been posted online by the Royal Collection Trust to commemorate the 200th anniversary of his death. As the Guardian reports, the collection “features material from the 16th to 18th centuries, from highly finished presentation maps of sieges, battles and marcheso rough sketches drawn in the field, depictions of uniforms and fortification plans, providing a vivid contemporary account of important theatres of war in Britain, Europe and America.”
George III was apparently an avid map collector. At his death his collection numbered some 55,000 maps: the maritime and topographic maps were given to the British Library; the military maps were kept by George IV for his own use. “Not all of them were collected by George III in the first instance: like most collectors, he not only purchased individual items but also acquired the collections of others.” [Tony Campbell]
Inspired by its appearance in a recent science fiction novel,1Matthew Edney explores the history of the odd word “cartograph”—a back formation of “cartography” whose existence suggests circumstances in which “map” is somehow insufficient. Edney traces three kinds of uses of the term: one referring to an early 20th-century instrument; one as a synonym for pictorial maps in the mid-20th century; and one, post-1980, that refers to map products that don’t, for some reason, adhere to Western cartographic ideals. (This piece expands on Edney’s book-length critique of the normative ideal of cartography, Cartography: The Ideal and Its History, which I reviewed here last October.)
On the left, Deutsche Bahn’s official network map of all Intercity and Intercity Express routes in Germany (PDF). On the right, a much more ambitious map of said network by Reddit user theflyingindonesian. Cameron Booth much prefers the unofficial map: while the official map is “incredibly average” (a putdown I will have to make a point of remembering), the unofficial map is “a major upgrade” that is “infinitely superior” to the official map. “I particularly like the dead straight trajectory of the lines from Hamburg down to Fulda, and the clear treatment of the potentially difficult and convoluted Rhine-Ruhr area. I also like the way that the routes for trains that pass through major stations get a ghosted-back line to link the routes across the (sometimes very large) station rectangles.” I know which one I’d rather spend a long time staring at.
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.
Sleeper trains are making something of a comeback, with services being restored and expanded after years of cutbacks, at least in Europe. In what may not be a coincidence, Jug Cerović has created Night Trains, a collection of maps of overnight train services around the world, done in his usual, standardized schematic transit network design language. Prints are available.
Columbus Globes, the century-old German globe manufacturer, lost its warehouse to a fire Thursday night. The 2,500-m2 building in Krauchenwies, Baden-Württemberg was completely destroyed, causing at least €1.5 million in damage. Police suspect arson: there have been a number of deliberately set fires in the Krauchenwies region in recent weeks—two at the Columbus site. News coverage (German only): DPA (Badische Zeitung, RTL, Süddeutsche Zeitung), SWR.
I haven’t been keeping up on what mapping and geospatial podcasts are out there. (My last post on the subject was nearly a decade ago.) Fortunately, GIS Lounge has a roundup of geospatial podcasts, most of which I was not aware of (see above); interesting to see that Very Spatial is still an ongoing concern.
This timelapse video showing 10 years of weather radar over the course of two hours is built from NEXRAD mosaic data at the Iowa Environmental Mesonet site. To be honest they could have gone even further back: the archived data for the U.S. goes back as far as 1995. But then you’d have a five-hour video, and who’d watch that? [Kottke]
