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]
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.
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:
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.”
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.
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.”
