Alum Robert Allison creates maps to track missing airliners

Even if you don’t find math the most engaging topic, it’s hard not to appreciate how NC State alumnus Robert Allison uses math to make interactive maps.

allisonWith the recent mystery of the missing Malaysia Airlines flight, many people have taken an interest in airplane disappearances. Allison has been interested in airplanes since he was a child because his father was a pilot in the Navy.

Allison, who earned his undergraduate (1987), masters (1990) and doctoral (1996) degrees at NC State, has worked with visual analytics at SAS for over 20 years. He recently developed an interactive map that shows the major unexplained airplane disappearances since 1948.

“NC State is where I learned how to do the graphics and use the SAS software and mapping techniques,” says Allison, who lives in Cary, N.C.

The interactive map he made was based off of one he found while researching the missing airplane on Bloomberg’s website. By downloading a spreadsheet of data from the Aviation Safety Network and using the SAS programming language, he created a new map that contained much more information than the original.

“My goal was just to find a map that I like and make a better version of it,” Allison says. “It’s easy to understand and easy to use.”

Allison focuses on making simple graphics that maximize efficiency. With the map he has created of missing airplanes, researchers could see if there are any trends of which airports these airplanes took off from or make more detailed data sets related to pilot experience or other factors that could have led to these lost airplanes.

Making maps is not new for Allison, but he still enjoys making them for their interactivity and potential for data analysis. Allison has created hundreds of maps and graphics, including maps that track the flu epidemic in California, show the debris from a space shuttle explosion and track iPhone versus Android phone usage by state.

“I’m currently working on a map to try to show all the known information about the missing Flight 370 on one single map,” Allison says.

These maps have the potential to help solve the mystery behind missing airplanes. Allison hopes that future efforts will be made with SAS technology to further this research and find out why some of these disappearances happen.
