The scene is visually exciting and appears to be another special effect dreamt up by the wizards of Hollywood.
Or is it?
Not So Far-Fetched
At Pennsylvania State University, researchers are working on something similar, combining GIS, natural language technology, cognitive engineering and the relatively new field of gestural science to create their version of the computer used by Cruise in Minority Report.
The difference is the technology will help governments better manage crises such as hurricanes, terrorist attacks, disease outbreaks and forest fires.
The high-tech wizardry behind the project is fascinating, but its purpose is basic: to help people work together better while making decisions as a crisis unfolds. Michael McNeese, one of the project investigators and a professor at Penn State's School of Information Sciences and Technology, defines a crisis as a series of ill-defined situations with information flowing in from many different sources.
"The problem in crisis management right now is information overload. It creates cognitive problems for the person trying to interpret the data and make decisions," he said.
The other problem facing crisis teams is their lack of skills in manipulating and analyzing spatial data using a geographic information system.
"Specialists in other domains can't access GIS when they need it the most," said Penn State geography professor Alan MacEachren, director of Penn State's GeoVISTA Center. "They have to rely on GIS experts, which isn't very efficient."
GIS is a critical element to managing data during a crisis, yet few local and state governments have the funds to cross-train crisis team leaders in intricate geospatial mapping techniques, according to MacEachren.
A significant problem is that current GIS technologies aren't designed for the end-user or for use in team efforts, such as crisis management, MacEachren said.
"There's been no study in a systematic way to predict what works and what doesn't in these situations," he added.
The center's mission is to coordinate integrated GIS research with emphasis on geovisualization.
MacEachren and McNeese are part of the GeoCollaborative Crisis Management (GCCM) project, a Penn State University research initiative that the National Science Foundation funded with $400,000 as part of its Digital Government Research Program.
MacEachren said researchers are currently using ArcIMS from ESRI.
"However, our interfaces approach and software is not dependant on a particular GIS," he added. "We are currently in the process of implementing a version using open source GIS software, relying on Geoserver + GeoTools."
McNeese, who spent 23 years in the Air Force designing command and control centers, is an expert in the arcane field of cognitive engineering. MacEachren is a professor of geography at Penn State and an expert in geographic visualization and cartography.
Rounding out the interdisciplinary GCCM team are professors Guoray Cai, an expert in human-geographic collaboration, and Rajeev Sharma, a specialist in the science of gestures for human-computer interaction. Researcher Sven Fuhrmann, who works in the field of geovisualization and cognitive science, is also a member.
Together, the team is spending three years studying how teams of government workers respond to crises collaboratively, and developing technology that will enable them to
