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.

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 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]
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.

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]
It turns out that I wasn’t finished talking about the maps drawn by Christopher Tolkien. My latest piece for Tor.com, “Celebrating Christopher Tolkien’s Cartographic Legacy,” went live at Tor.com this morning. It looks at the collaborative process between J. R. R. Tolkien and his son Christopher as father and son tried to make the narrative agree with the map, and vice versa; takes a deep dive into Christopher’s mapmaking technique; and tries to assess the impact of his maps on fantasy mapmaking.
