Century-Old Maps Reveal Long-Term Abundance of Kelp Beds

Published on by Jonathan Crowe

Comparing century-old maps of kelp beds in the Pacific Northwest to modern aerial surveys, a University of Chicago professor was able to track the long-term abundance and health of the beds, which in most cases remained remarkably constant: Journal of Ecology article. The kelp bed maps, made from surveys in 1911 and 1912, were the result of U.S. concern about the nation’s potash supply, which in the runup to World War I was largely imported from Germany. The kelp beds were, for some reason, seen as an alternative fertilizer source. That plan never came to fruition, but the maps remained, to be put to use for an entirely different purpose more than a century after they were made. [WMS]

The Texas Restorers Who Examined the Fake Globe Gores

Still more coverage of the cancelled auction of the Waldseemüller globe gores that were later identified as fakes, this time from the Houston Chronicle, which pursues the local-interest angle by talking to Michal and and Lindsay Peichl, restorers from Clear Lake, Texas (their firm is Paper Restoration Studio) who were brought in to examine the gores along with other experts. Michal says it didn’t take him long to figure it out:

“My first reaction when I saw the picture was, ‘Oh my God, this is a fake,'” said Michal. “You could tell this was a sheet of paper pulled from a book binding board.

“It was printed on a piece of paper that used to be glued on the back of book and that was a red flag to me because as a forger, if you want to make a fake, that’s where you would go to get a clean sheet of paper.”

Morphology

Published on by Jonathan Crowe

Yesterday I told you about Mapzen’s announcement that it would be closing down at the end of the month. So it’s bittersweet that I find, in my to-do list of links to post here, a Mapzen project. Morphology is a tool that abstracts the map into an unlabelled set of lines, patterns and forms. The default view combines several different features, but you can isolate single features: airports, roads, parks, bodies of water, and more. The work of Mapzen cartographer Geraldine Sarmiento, it was first presented as a NACIS talk last October. [Atlas Obscura]

Mapzen Is Shutting Down

Published on by Jonathan Crowe

Mapzen announced today that they were shutting down at the end of January 2018.

Our hosted APIs and all related support and services will turn off on February 1, 2018. You will not be charged for API usage in December/January. We know this is an inconvenience and have provided a migration guide to similar services for our developer community. Our goal is to help as much as possible to ensure continuity in the services that you have built with us.

Fortunately, the core products of Mapzen are built entirely on open software and data. As a result, there are options to run Mapzen services yourself or to switch to other service providers.

No reason was given for the move.

The Great Map of Movieland

Published on by Jonathan Crowe

The Great Map of Movieland is a whimsical map that plots 1,800 movie titles on an imaginary terrain. Film genres appear as regions (Adventure Plains, Coming of Age Peninsula) and the films themselves appear as towns, with town size correlating to a film’s importance. (It’s a bit odd to see Star Wars and Star Trek in the Adventure Plains rather than the Sci-Fi Mountains, and I’m not sure what the significance of the highways are, nor why Casablanca and The Return of the King are right next to one another.) The brainchild of 31-year-old French designer David Honnorat, the map was a subject of a successful Kickstarter campaign last fall and is now available, via David’s store, as a 26×36″ print; the price is €40. [Boing Boing]

New Jersey Borough to Close Streets to Congestion-Rerouted Traffic

Published on by Jonathan Crowe

When your navigation app (e.g. Waze) suggests an alternate route to avoid congestion, that has knock-on effects on the communities you’re routed through, particularly when a lot of traffic gets pushed onto quiet residential streets.  That’s the situation in Leonia, New Jersey, the New York Times reports, where later this month the police will be closing some 60 streets to non-local traffic in hopes of routing all that Wazer traffic somewhere else. Some of the somewhere elses aren’t happy with this move, naturally. [Engadget]

A Digital Cartographer Tries Drawing by Hand

Published on by Jonathan Crowe
John M. Nelson

Fresh from trying to replicate hand-drawn effects (or even papercut effects) digitally, John M. Nelson has crossed over and begun attempting actual hand-drawn maps. Here he documents how he created a hand-drawn map as a Christmas present; here he gives hillshading by hand a try.

Early Radar Maps of Antarctica Digitized

Published on by Jonathan Crowe

Nature: “Glaciologists will soon have a treasure trove of data for exploring how Antarctica’s underbelly has changed over nearly half a century. An international team of researchers has scanned and digitized 2 million records from pioneering aeroplane radar expeditions that criss-crossed the frozen continent in the 1960s and 1970s. […] The digitized data extend the record of changes at the bottom of the ice sheet, such as the formation of channels as Antarctica’s ice flows, by more than two decades.” (Modern radar mapping of Antarctica apparently only began in the 1990s.)

U.S. Wildfire Causes, 1980-2016

Published on by Jonathan Crowe

Jill Hubley has mapped the causes of wildfires in the United States from 1980 to 2016, based on Federal Wildland Fire Occurrence Data. The map toggles between main causes (human and natural) and specific cause; there’s also a chart ranking the causes.

The highest and lowest ranked causes are highlighted when the chart loads. These represent the cumulative ranking across all years. Lightning, a natural cause, often floats to the top, but that’s only because on the human side, the vote is split between more than twenty options. Lightning doesn’t predominate in all states, though. In Alabama, the number one cause is pyromania. In Indiana, it’s brakeshoes. In Minnesota, it’s field burning. There are a couple of overall trends, too. Smoking is going down as a cause, and powerlines are going up.

Canadian Geographic’s (and Chris Brackley’s) Best Maps

Published on by Jonathan Crowe
Canadian Geographic

Canadian Geographic looks at the best maps it published in 2017. It did the same in 2016 and in 2015. The funny thing about the maps in these year’s-best posts is that they’re all by CG’s in-house cartographer, Chris Brackley, who the RCGS is clearly glad to have on board—and based on what I can see of his work, they should be.
