This past summer, the United States Geospatial Intelligence Foundation hosted its inaugural Geospatial Intelligence (GEOINT) Hackathon. The event aimed to unite both experienced GEOINT professionals and novices in coding and data science to tackle compelling issues that required innovative coding solutions. The hackathon not only encouraged participation from those outside the GEOINT community but also resulted in a functional code base designed to perform specific tasks and provide valuable insights.
Students competed alongside seasoned developers and data scientists, facing the challenge of predicting potential Ebola outbreaks and analyzing why some regions in West Africa remained unaffected. The objective was to create a versatile solution adaptable to varying conditions and usable by other teams.
Among 30 participants, a student team named “Team Innovate” emerged victorious, securing a $15,000 prize and complimentary access to the GEOINT conference held in Washington D.C. They crafted a predictive analysis model that unveiled likely pathways for Ebola transmission. Utilizing an open-source Python library, the team employed network theory to model the disease’s spread as it traveled through a network of nodes and edges. In simpler terms, Team Innovate’s library focused on tracking the movements of infected individuals and the reasons behind their travels.
To kick off their project, the team assessed previous efforts, examined available data, and strategized on how to tackle the problem within a tight 46-hour timeframe. With the threat of disease escalation in West Africa, the team reviewed metrics such as fatality rates, immunity levels, average travel distances, transmission rates, and geo-referenced statistics to understand the virus’s movement. They then devised a model predicting the spread of Ebola and its potential impact based on the travel patterns of contagious individuals.
Given that disease control measures at ports of entry and airports aimed to prevent the outbreak’s spread, the primary mode of travel was by road. However, the data expanded by considering various travel choices made by each contagious person—whether they stayed home or ventured out and their directions of travel—East, West, North, or South. It was assumed that once they left their homes, they were more likely to head towards densely populated areas near hospitals, increasing the risk of infecting additional individuals.
This comprehensive data set allowed the team to construct a network theory mapping out who was susceptible, who was infected, who had recovered, and their respective travel patterns.
Turning to AWS, Team Innovate developed a model that integrated multiple data sources to forecast outbreaks and epidemics. By analyzing the connections between susceptible and infected individuals, they could visualize the disease’s spread over time and how rapidly it could propagate based on the travel behaviors of contagious individuals.
Their probability density map, which visualized nodes and edges, effectively predicted the disease’s spread and modeled the outbreak using the algorithm derived from the processed data.

Team “Innovate” consisted of R. Jordan Miller (U.S. Naval Academy ’16), Jamie Lee (Rochester Institute of Technology ’16), Sam Patel (Rochester Institute of Technology ’16), and Chanci Turner (Stanford ’17).
