The Need for Openness in Data Journalism
Apr 10th, 2014 by Tom Johnson

An excellent, thoughtful essay by Brian Keegan on the need for openness — and better application of [social] scientific methods — by journalists.

The Need for Openness in Data Journalism

Do films that pass the Bechdel Test make more money for their producers? I’ve replicated Walt Hickey’s recent article in FiveThirtyEight to find out. My results confirm his own in part, but also find notable differences that point the need for clarification at a minimum. While I am far from the first to make this argument, this case is illustrative of a larger need for journalism and other data-driven enterprises to borrow from hard-won scientific practices of sharing data and code as well as supporting the review and revision of findings. This admittedly lengthy post is a critique of not only this particular case but also an attempt to work through what open data journalism could look like.  [Read more]

MOOC from Penn State: Maps and the Geospatical Revolution
Apr 7th, 2014 by Tom Johnson

A free MOOC on GIS and spacial analysis will be offered by Pennsylvania State University starting 30 April 2014. 

The course link and description:

Maps and the Geospatial Revolution
Learn how advances in geospatial technology and analytical methods have changed how we do everything, and discover how to make maps and analyze geographic patterns using the latest tools.


About the Course

The past decade has seen an explosion of new mechanisms for understanding and using location information in widely-accessible technologies. This Geospatial Revolution has resulted in the development of consumer GPS tools, interactive web maps, and location-aware mobile devices. These radical advances are making it possible for people from all walks of life to use, collect, and understand spatial information like never before.

This course brings together core concepts in cartography, geographic information systems, and spatial thinking with real-world examples to provide the fundamentals necessary to engage with Geography beyond the surface-level. We will explore what makes spatial information special, how spatial data is created, how spatial analysis is conducted, and how to design maps so that they’re effective at telling the stories we wish to share. To gain experience using this knowledge, we will work with the latest mapping and analysis software to explore geographic problems.

NPR: “So You Think You’re Smarter Than A CIA Agent “
Apr 2nd, 2014 by Tom Johnson

Good NPR piece on the wisdom of crowd-based analysis at the Good Judgment Project

“The morning I met Elaine Rich, she was sitting at the table of her small town home in suburban Maryland trying to estimate refugee flows in Syria.

It wasn’t the only question she was considering; there were others:

Korea launch a new multistage missile before May 10, 2014?

Will Russian armed forces enter Kharkiv, Ukraine, by May 10? Rich’s answers to these questions would eventually be evaluated by the intelligence community, but she didn’t feel much pressure because this wasn’t her full-time gig.

“I’m just a pharmacist,” she said. “Nobody cares about me, nobody knows my name, I don’t have a professional reputation at stake. And it’s this anonymity which actually gives me freedom to make true forecasts.”

Rich does make true forecasts; she is curiously good at predicting future world events.”[more]

Esri Lauches ArcGIS Open Data Site

“Esri has launched ArcGIS Open Data, a website with the tag line “Explore open data from all over the world.” Those who visit are invited to: Collaborate, Discover New Data and Visualize and Analyze. Sunday afternoon (March 9, 2014) the website had 81,301 datasets.

“I did a search on EPA since I know the EPA was a participant in the first discussions of ArcGIS Online Open Data Program (Directions Magazine coverage). What I found were many EPA datasets (286) with creation dates in the past few years. There was no informatoin about when the dataset was added to this portal. Alongside a paragraph of description I found these data associated with ctdphonline: EPA Faciliites:”
