Opening today at the Boston Public Library’s Leventhal Map Center, Building Blocks: Boston Stories from Urban Atlases is an exhibition that explores street-level changes to Boston in the period between the Civil War and World War II. Media release.

Building Blocks: Boston Stories from Urban Atlases features rare materials from the BPL’s historic collection of maps and atlases alongside lithographs, photographs, and sketches of familiar local landscapes. Visitors will discover how the atlas collections opens up a world of fascinating stories, with vignettes including the city’s first African Meeting House in the heart of Beacon Hill, landmarks of leisure like the “Derby Racer” and “Giant Safety Thriller” amusement rides in Revere, public health infrastructure on Gallops Island in Boston Harbor, and many more.

The in-person exhibition at the BPL’s Central Library opens today; a digital version will follow online. Runs until 19 August 2023. A curatorial introduction will take place next Wednesday.

Meanwhile, a permanent exhibition, Becoming Boston: Eight Moments in the Geography of a Changing City, also opens today at the Leventhal: “In the eight cases of this exhibition, we follow the changing spatial forms of the place we now call Boston—from before the landscape carried that name all the way through the struggles, clashes, and dreams that continue to reshape the city today.”

New Fantasy Novel: The Map and the Territory

Published on by Jonathan Crowe

Book cover: The Map and the Territory by A. M. Tuomala I’m always interested in fantasy novels in which maps play a role beyond the endpapers—where maps or mapmakers are a key element of the story. So I’m noting for future reference The Map and the Territory by A. M. Tuomala (Candlemark and Gleam, Dec. 2022), which has a wizard and a cartographer as its protagonists. Nerds of a Feather has a review.

The Overture Map Foundation

Published on by Jonathan Crowe

Announced earlier this month, the Overture Map Foundation is an initiative founded by Amazon Web Services (AWS), Meta (i.e. Facebook), Microsoft and TomTom to build an ecosystem of interoperable open map data—an ecosystem, note, that does not at the moment include Apple, Esri or Google, so presumably this is a way for smaller owners of map data (at least for TomTom values of smaller) to form Voltron punch above their weight by making it easier to combine and share resources. From the press release:

Multiple datasets reference the same real-world entities using their own conventions and vocabulary, which can make them difficult to combine. Map data is vulnerable to errors and inconsistencies. Open map data can also lack the structure needed to easily build commercial map products and services on top.

Making it easier to combine data—one of Overture’s aims is to create “a common, structured, and documented data schema”—sounds an awful lot like a way to address James Killick’s complaint about the geospatial industry’s lack of common data standards (previously). It also sounds like TomTom’s map platform, announced last month, is part of something bigger.

Given the talk about open map data, it’s not surprising that the OpenStreetMap team has some thoughts about the announcement, and about how Overture and OSM might work together in the future.

Projection Connections: A Genealogy of Map Projections

Projection Connections: a diagram showing the relationships between various map projections by Daniel Huffman

Fresh off of producing a (now sold-out) line of map projection trading cards, Daniel Huffman has produced a 16×24-inch poster showing the surprisingly close and entangled relationships between the various map projections.

I first learned about a couple of these connections several years ago. I don’t quite remember how or where, but I found out that the Mercator projection was equivalent to a Lambert Conformal Conic with the standard parallels set opposite each other across the Equator. And that if you moved both those parallels up to a pole, you got a Stereographic. My mind was suitably blown, and I saved it as a fun fact to share with people. This year, while working on The Projection Collection, I spent a lot of time on daan Strebe’s site looking up details, and I often saw his notes (usually derived from Snyder/Voxland) about how projections were related to each other. I started to realize there were a lot of these connections out there, and I thought it might be fun to diagram them in some way.

The diagram is digital-only (PDF) and donationware.

Georeferencing Familiar Places

Published on by Jonathan Crowe

On the Leventhal Map Center’s website, Ezra Acevedo describes what it’s like to georeference a century-old atlas of your hometown. “Spending many hours poring over maps of such a well known place was really exciting. My knowledge of the town coupled with its resistance to change meant that the historic maps of Ipswich weren’t all that difficult to line up with the modern map. However, I did learn four important lessons while georeferencing my hometown.”

NYC Tree Map

The impressive and/or insane thing about the New York City Tree Map is that it maps individual trees: now about 860,000 of them, all managed by the city’s parks department on city streets and in parks, down to the species and trunk diameter, which also means you can filter for those parameters, plus get most recent inspection and tree care data on specific trees. You can even favourite individual trees. If trees had social media accounts, they’d be here. [Bloomberg CityLab]

2022 Holiday Gift Guide

Published on by Jonathan Crowe

Once again, I’m a bit late with my annual gift guide. The idea of which is, if you have a map-obsessed person in your life and would like to give them something map-related—or you are a map-obsessed person and would like your broad hints to have something to link to—this guide may give you some ideas.

This list is a long way from comprehensive. Be sure to check out gift guides from previous years: see, for example, the 2021, 2019, 2018 and 2017 gift guides (in 2020 I focused on map stationery). Much of what’s listed may still be available. And even more books are listed on the Map Books of 2022 page.

Please keep in mind that this is not a list of recommendations: what’s here is mainly what I’ve spotted online, and there’s probably a lot more out there. In many cases I haven’t even seen what’s listed here, much less reviewed it: these are simply things that look like they might be fit for gift giving. (Anyone who tries to parlay this into “recommended by The Map Room” is going to get a very sad look from me.)

Finally, this post contains affiliate links; I receive a cut of the purchase price if you make a purchase via these links.

The Bois Forte Native Names Map

Published on by Jonathan Crowe

Bois Forte Native Names Map

The Bois Forte Native Names Map collects more than 100 original Ojibwe names in the traditional territory of the Bois Forte Band of Chippewa, in what is now northeastern Minnesota. The hand-drawn map is the result of a two-year collaboration between the band, Ely Folk School and volunteer artists. A limited first-edition print is available via a school fundraiser; plans are afoot for a mass-produced paper map, as well as an online version. Details here; also see the Star Tribune’s coverage. Thanks to Paul for the link.

Satellite Observations of Ukraine’s Wheat Harvest

Satellite observations have made it possible to evaluate the success of Ukraine’s wheat and barley harvest, even in active war zones or occupied territories. NASA Earth Observatory reports that the harvest was, in the end, larger than expected: “At the outset of Russia’s full-scale invasion in February, some analysts cautioned that 20 to 30 percent of Ukraine’s winter crops might not be harvested at the end of the summer. However, NASA Harvest’s analysis indicates that 94 percent of the winter crop was harvested, including 88 percent of winter crops in areas not controlled by Ukraine.”

The Privacy Implications of a Slight URL Change

Published on by Jonathan Crowe

Garrit Franke thinks a change in Google Maps’s web address—it now redirects from a subdirectory, maps.google.com, to a folder on Google’s root directory, google.com/maps1—means that location permission given to Google Maps (a normal thing to do when using maps) could be applied across all of Google’s services without asking for additional permissions.
