Mapping Tornado Migration

John Nelson’s map of tornado migration in the United States, showing the seasonal variations in tornado occurrence, is a master class in data visualization and design—in deciding on the right way to present geographic information. The map combines three styles—impressionistic choropleth, weighted mean centre movement diagram, and small multiple—to present month-by-month information all at once; in the accompanying text (also here), Nelson discusses some of the alternatives he could have chosen instead. And in a separate post he talks about how he made the map. [Esri]

Coming Soon: Kenneth Field’s Open Online Course on Cartography

Esri will be hosting a free, six-week massive open online course (MOOC) on cartography later this year. Called Cartography., it’s taught by Kenneth Field and coincides with the release of Field’s textbook of the same name.

Each weekly lesson in the Cartography. MOOC focuses on the creation of one exemplary map that draws together key cartographic ideas. Lessons consist of about two hours of content, including video discussions, guided and self-guided exercises using ArcGIS Pro and ArcGIS Online, quizzes, interactions between students and instructors, and supplemental resources. Participants who engage with all the course content will receive a certificate of completion and a discount code to purchase Cartography., the book, should they wish to continue their learning.

Registration opens on 18 April and continues until 2 May. It is, as I mentioned, free; Esri expects more than 10,000 people to sign up.

Cartography., the book, is currently scheduled to come out in June.

Two More Books for 2017

The year 2017 is almost at an end, but two more map books, published last month, have just come to my attention (via, as usual, the WMS’s indefatigable Bert Johnson). These, then, are very late additions to the Map Books of 2017 page:

Sad Topographies by Damien Rudd (Simon & Schuster), who “journeys across continents in search of the world’s most joyless place names and their fascinating etymologies.” This appears to be an outgrowth of the author’s sadtopographies Instagram account.1

New Lines: Critical GIS and the Trouble of the Map by Matthew W. Wilson (University of Minnesota Press). “Seeking to bridge a foundational divide within the discipline of geography—between cultural and human geographers and practitioners of Geographic Information Systems (GIS)—Wilson suggests that GIS practitioners may operate within a critical vacuum and may not fully contend with their placement within broader networks, the politics of mapping, the rise of the digital humanities, the activist possibilities of appropriating GIS technologies, and more.”

How to Build a Fire Map

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.”

ArcticDEM Release Six Adds Eurasia

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]

Tomlinson’s Ph.D. Thesis Now Available

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.

Cartographies of Disease

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).

Maclean’s Profiles Nova Scotia’s COGS

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.

Making Maps, Third Edition

making-maps-3rdOn 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.)
