Simulations becoming third way to find scientific truth
May 6th, 2014 by Tom Johnson

Simulation modeling has been one of the cornerstones of the IAJ since its founding 20+ years ago.  Nice to see other disciplines catching up.  (That’s a joke, kid.)

Simulations becoming third way to find scientific truth  —

Computer simulation is increasingly being used as a third method to establish scientific truth, alongside theory and experimentation. Astrophysicist Kevin Heng breaks down the pros and cons of computer simulations in a perspective piece in American Scientist. “Simulations as a third way of establishing scientific truth are here to stay. The challenge is for the astrophysical community to wield them as transparent, reproducible tools, thereby placing them on an equally credible footing with theory and experiment,” he writes.

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
Mar 10th, 2014 by Tom Johnson

From Directions Magazine, whose reviewer writes:

Sunday, March 09, 2014
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:”

The 11th Crime Mapping Research Conference
Jun 25th, 2011 by Tom Johnson

The National Inst. of  Justice was one of the early adopters of GIS perspectives and technologies.  For the past decade, it has funded impressive research in the field, the results of which typically can transfer to other disciplines and questions related to space, time and events.  Note, too, that both the pre-workshops and the conference are FREE.

National Institute of Justice Registration is now open for the rescheduled 11th Crime Mapping Research Conference!

The 11th Crime Mapping Research Conference

When: October 19–21, 2011 Pre-conference Workshops: October 17–18

Where: Hilton Miami Downtown Miami, FL


About: The Crime Mapping Research Conference is about understanding crime, criminal justice, and public safety and their effect on, and by, places. At the 11th conference, you can explore: the latest research findings practical applications technology demonstrations policy results

David Rumsey Map Collection adds 1,634 new maps
Mar 19th, 2011 by Tom Johnson

From Rumsey's site:

1,634  new maps and images have been added to the David Rumsey Map Collection, bringing the online collection to over 26,000 maps and images. Included in this addition are five issues of Colton's General Atlas of the World dated from 1865 to 1886. Also two editions of Schonberg's Standard Atlas of the World, 1865 and 1867. Sheets from two national surveys: six composite images of the entire Wheeler Survey of the U.S. West, 1876, and the first 338 sheets of the massive 19th century survey of Germany, Karte des Deutschen Reiches, 1893 (the remaining 336 sheets will follow in the next update). Added are elegant maps from the Atlante Geographico de Agostini, 1952, and a complete set of all the Shell Oil Company Automobile Road maps of North America, 1956.

An AJ Watershed
Feb 25th, 2011 by Tom Johnson

This is a great weekend to be in Raleigh, North Carolina. Forget about the BBQ. Instead, head to the annual NICAR (National Institute for Computer-Assisted Reporting) confab at the Raleigh Marriott City Center. Or if it's too far or too late to go, then go to Twitter and do a search for the hashtag #NICAR11. Many, many attendees are doing a great job of tracking multiple presentations and hands-on workshops and then posting wonderful links to PowerPoint slides, Tipsheets (often being shared via Google Docs) and the debate about which is really the best style BBQ.

The reason we are calling this a “watershed” is that I have attended these for nearly 15+ years, and I've never seen such a wonderful compote of traditional journalists PLUS digital-savvy folks coming in from non-journalism backgrounds. This is the only way journalism — aggressive, watchdog journalism — can be saved.

Thanks to all for your investments in time, money and generous sharing.
