Last October Robin Kraft posted an online map of the northern California wildfires showing satellite imagery from before and after the fires (see previous entry); today he’s posted a blog entry explaining how he built it, in great technical detail. The timing is not accidental: “There is another fire raging in Los Angeles right now — if DigitalGlobe and Planet release their data, you can use this guide to make your own map.”
The sixth release of the ArcticDEM initiative adds 32 percent more terrain data, mostly in Russia and Scandinavia. ArcticDEM provides a two-metre-resolution digital elevation model for arctic regions north of the 60th parallel, plus those bits of Alaska, Greenland and the Kamchatka Peninsula south of 60. The final product is due out next year. More at Earth & Space Science News. [GIS and Science]
James Cheshire reports that the Ph.D. thesis of the “father of GIS,” Roger Tomlinson, has been digitized. Tomlinson completed his thesis, “Geographical Information Systems, Spatial Data Analysis and Decision Making in Government,” at the University College London’s Department of Geography in 1974. It can be downloaded as a PDF at this link.
The revised edition of Tom Koch’s Cartographies of Disease: Maps, Mapping, and Medicine—“a comprehensive survey of the technology of mapping and its relationship to the battle against disease”—is now out from Esri Press. (Or at least it’s scheduled to be: the paperback is not yet in stock at Amazon.) [GIS Lounge]
Koch is also the author of Disease Maps: Epidemics on the Ground (2011).
Nova Scotia Community College’s Centre of Geographic Sciences, a tiny, 200-student campus in Lawrencetown, Nova Scotia, gets two writeups in Canada’s national newsmagazine, Maclean’s, as part of its annual campus guide: its unique marine geomatics program is profiled here, and the W. K. Morrison Special Collection, which I told you about last June, is profiled here.
On the Making Maps: DIY Cartography blog, John Krygier announces the third edition of his and Denis Wood’s Making Maps: A Visual Guide to Map Design for GIS, out this month from Guilford Press. The new edition of this extremely visual guide includes more than 40 new pages of content, Krygier says, plus new maps and examples and other changes he details in the blog post. Buy at Amazon.
(I reviewed the first edition back in 2006. I knew a lot less about cartography back then, and I suspect it shows.)
Is Sexism a Problem in GIS? Caitlin Dempsey Morais of GIS Lounge grapples with a thorny subject. “Over a two week period in September of 2015, I opened a survey on GIS Lounge to those working in the geospatial industry in order to take a look at the question of, ‘is sexism in the workplace an issue for women (and men) working in GIS?’ This article reports back on the results from that survey.”
Mapping the Past: GIS Approaches to Ancient History, a conference hosted by the Ancient World Mapping Center (the folks behind the Barrington Atlas), takes place at the University of North Carolina, Chapel Hill, from 7 to 9 April 2016. It’s open to the public. Here’s the full schedule. [via]

Zero degrees longitude, zero degrees latitude is literally nowhere: situated in the middle of the open ocean, off the coast of Africa in the Gulf of Guinea, the only thing to mark its presence is a weather observation buoy [via]. But it’s also a significant set of coordinates, in that it’s the location you might get in the case of geocoding errors.
Hence the invention of Null Island, an imaginary place to flag geocoding failures. It shows up in version 1.3 of Natural Earth, for example, as an island one square metre in size, but coded so that it would never appear in an actual map. Gary Vicchi explains Null Island in more detail. As is the way of fictional places, Null Island has grown in the imagination: it has its own website, replete with sections on its history, geography, people and economy, and its own flag.
[A]s Google aimed its maps mostly at consumers, Esri was able to hold on to its revenue base among power users in business, government and other organizations. Google is great for directions or locating your home on Zillow. But if you are, say, the Bavarian police charged with securing the G7 Summit near Munich and need a detailed real-time dashboard that can pinpoint every delegation, police officer, emergency vehicle, first responder, protest site, road closure, mountain trail and access point to the summit’s venue, you’ll use Esri. Last year Google pulled the plug on a halfhearted push into enterprise maps and began moving its customers to Esri.
Notable that Esri has stayed private rather than raising capital through the stock market, which in the tech sector is just unbelievable. Its estimated value is $3 billion.
