After Mitsuo Fuchida commanded the air attack on Pearl Harbor, he drew a map to report on the damage his planes inflicted on the U.S. ships. That map, held by the Library of Congress, is the subject of an interactive story map from the Library: “This is the story of how Fuchida made the map, the history surrounding it, and an opportunity for the reader to interactively explore the map’s contents.” [Maps Mania]
Last week Google announced “over 100 AI-powered improvements to Google Maps” would be coming this year; these include bringing Live View indoors, a new air quality map layer, eco-friendly routing, and support for curbside pickup in business listings.
A new online exhibition at Stanford Libraries’ Rumsey Map Center: Mapping the Islamic World: The Ottoman, Safavid and Mughal Empires. Curated by guest curator Alexandria Brown-Hejazi, the exhibition, which opened last week, “explores maps of the Islamic World, focusing on the ‘Gunpowder Empires’ of Ottoman Turkey, Safavid Persia, and Mughal India. […] A rich cartographic exchange took place between these three empires and European powers, as maps were used to chart their expansive territories, military campaigns, and trade routes.”
Two workshops/courses coming in June:
Australian author and illustrator Kathleen Jennings will teach a workshop on fantasy mapmaking in June: the focus of Map Making and World Building is “on story and art,” the mapmaking illustrative rather than cartographical, and in general it seems to be about the relationship between map and story. The workshop will take place on 19 June both in-person (at the Queensland Writers Centre in Brisbane) and via livestream; tickets range from A$35 to A$100, depending.
A History of Maps and Mapping, a short introductory online course taught by Katherine Parker as part of the London Rare Books School’s program of summer courses, “will challenge students to destabilize and broaden the traditional definition of ‘map’, and to recognize maps as socially constructed objects that are indicative of the values and biases of their makers and the cultures that created them. Students will learn how to analyse and catalogue maps for a variety of research purposes, and to discuss changes in map technology and style without recourse to a progressive narrative of scientific improvement.” Matthew Edney will supply a guest lecture. The course runs from 29 June to 2 July and costs £100 (student) or £175.
The New York Times maps partisan sorting in America—the tendency for voters to self-select into areas where people think and vote the same way they do—down to the neighbourhood level.
The maps above—and throughout this article—show their estimates of partisanship down to the individual voter, colored by the researchers’ best guess based on public data like demographic information, voter registration and whether voters participated in party primaries.
We can’t know how any individual actually voted. But these maps show how Democrats and Republicans can live in very different places, even within the same city, in ways that go beyond the urban-suburban-rural patterns visible in aggregated election results.
It goes beyond racial, urban vs. suburban vs. rural and house vs. apartment splits, to the point where researchers are wondering whether Americans are “paying attention to the politics of their neighbors” when they decide where to live. This has implications not only in terms of electoral targeting (e.g. gerrymandering, voter suppression), but in terms of basic social cohesion.
The maps are based on research by Jacob R. Brown and Ryan D. Enos published earlier this month in Nature Human Behavior.

Matthew Edney reviews Rasmus Grønfeldt Winther’s When Maps Become the World (University of Chicago Press, 2020), a philosophy of science book that engages with maps and representation—with what Winther calls “map thinking.” Edney isn’t convinced by Winther’s approach: “Winther remains committed to outmoded and deeply flawed concepts of the nature of ‘the map’ that, to be honest, call into question the entire project.”
RMTransit, a transit enthusiast YouTube channel, looks at some of the shortcomings of transit maps: how maps tend to fail at things like mode (tram vs. subway) or frequency. Very much from a rider perspective rather than from the perspective of map design.
Writing at The Conversation, geographers Derek Alderman and Joshua Inwood explore African American examples of “counter-mapping,” from maps made by the Black Panthers proposing new police districts to modern interactive maps of lynchings and police violence. “Black Americans were among the earliest purveyors of counter-mapping, deploying this alternative cartography to serve a variety of needs a century ago.” [Osher]

The 100 millionth edit to OpenStreetMap was uploaded today, the OpenStreetMap Blog reports. “This milestone represents the collective contribution of nearly 1 billion features globally in the past 16+ years, by a diverse community of over 1.5 million mappers.”
National Geographic looks at the rivalry between two early cartographers of Mars who based their maps on observations made during Mars’s “Great Opposition” in 1877: Nathaniel Green, whose Mars “was a delicately shaded world with landforms that gradually rose from vast plains and features that blended into one another” (pictured here) and Giovanni Schiaparelli, whose Mars had more detail—including those famous canals—but was less accurate.
Kenneth Field has released a dasymetric dot density map of the 2020 U.S. presidential election results. One dot equals one vote. “Data at a county level has been reapportioned to urban areas. Dots are positioned randomly.” It’s in the same vein as his 2016 map, which went all kinds of viral when he posted it in early 2018. A high-resolution downloadable poster is here; an interactive version is here.
Penn State University Libraries’ collection of Pennsylvania Sanborn fire insurance maps dates to 1925, which means that as of this year they’re in the public domain—and freely available to use. Meanwhile, Maps Mania has a roundup of other fire insurance maps resources. The Library of Congress has a collection of 50,000 Sanborn atlases, 35,000 of which are available online (collections, navigator). In the United Kingdom, fire insurance maps were produced by Charles E. Goad Ltd.; Goad maps are available via the British Library and the National Library of Scotland.
Fire insurance maps are an invaluable resource for historical researchers: they’re extremely detailed snapshots of the built environment of virtually every city and town, and there are usually several such snapshots (I’ve seen at least three for my little village, for example), so you can chart a town’s growth over time at a level of detail an OS, quad or topo map can’t match.
Google explains how they identify and take action against fraudulent content—fake reviews, fake listings, content vandalism—on Google Maps.
Crowdsourced incident reporting—a feature already available in Google Maps and Waze—is coming to Apple Maps: the beta release of iOS 14.5 enables users to report accidents, road hazards and speed checks, with Siri and CarPlay integration. More at CNet’s Roadshow and MacRumors, among others; the final, public release of iOS 14.5 should come out some time in the spring, I think.
